II. Self-Regulatory Organization’s Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change In its filing with the Commission, the Exchange included statements concerning the purpose of and basis for the proposed rule change and discussed any comments it received on the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. The Exchange has prepared summaries, set forth in sections A, B, and C below, of the most significant aspects of such statements. A. Self-Regulatory Organization’s Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change 1. Purpose The Exchange proposes to make permanent its Pilot Program that permits the Exchange to list FLEX Options whose exercise settlement value is derived from closing prices on the last trading day prior to expiration that expire on or within two business days of a third Friday-of-the-month expiration day for a non-FLEX Option (other than QIX options) (‘‘FLEX PM Third Friday’’). The Securities and Exchange Commission (the ‘‘Commission’’) approved a Cboe Options rule change that, among other things, established a pilot program regarding permissible exercise settlement values for FLEX Index E:\FR\FM\28APN1.SGM 28APN1 26354 Federal Register / Vol. 88, No. 82 / Friday, April 28, 2023 / Notices ddrumheller on DSK120RN23PROD with NOTICES1 Options on January 28, 2010.3 The Exchange has extended the pilot period numerous times, which is currently set to expire on the earlier of May 8, 2023 or the date on which the pilot program is approved on a permanent basis.4 The Exchange hereby requests that the Commission approve the FLEX PM Third Friday Pilot Program on a permanent basis. By way of background, when cashsettled 5 index options were first introduced in the 1980s, settlement was based on the closing value of the underlying index on the option’s expiration date. The Commission later became concerned about the impact of P.M.-settled, cash-settled index options 3 Securities Exchange Act Release No. 61439 (January 28, 2010), 75 FR 5831 (February 4, 2010) (SR–CBOE–2009–087) (‘‘Approval Order’’). The initial pilot period was set to expire on March 28, 2011, which date was added to the rules in 2010.

At the same time the permissible exercise settlement values pilot was established for FLEX Index Options, the Exchange also established a pilot program eliminating the minimum value size requirements for all FLEX Options. See Approval Order, supra note 3. The pilot program eliminating the minimum value size requirements was extended twice pursuant to the same rule filings that extended the permissible exercise settlement values (for the same extended periods) and was approved on a permanent basis in a separate rule change filing. See id; and Securities Exchange Act Release No. 67624 (August 8, 2012), 77 FR 48580 (August 14, 2012) (SR–CBOE–2012–040) (Order Granting Approval of Proposed Rule Change Related to Permanent Approval of Its Pilot on FLEX Minimum Value Sizes). 5 The seller of a ‘‘cash-settled’’ index option pays out the cash value of the applicable index on expiration or exercise. A ‘‘physically settled’’ option, like equity and ETF options, involves the transfer of the underlying asset rather than cash.

VerDate Sep<11>2014 18:44 Apr 27, 2023 Jkt 259001 on the markets for the underlying stocks at the close on expiration Fridays. Specifically, certain episodes of price reversals around the close on quarterly expiration dates attracted the attention of regulators to the possibility that the simultaneous expiration of index futures, futures options, and options might be inducing abnormal volatility in the index value around the close.6 Academic research at the time provided at least some evidence suggesting that futures and options expirations contributed to excess volatility and reversals around the close on those days.7 In light of the concerns with P.M.-settlement and to help ameliorate the price effects associated with expirations of P.M.-settled, cash-settled index products, in 1987, the Commodity Futures Trading Commission (‘‘CFTC’’) approved a rule change by the Chicago Mercantile Exchange (‘‘CME’’) to provide for A.M. settlement 8 for index futures, including futures on the S&P 500.9 The Commission subsequently approved a rule change by Cboe Options to list and trade A.M.-settled SPX options.10 In 1992, the Commission approved Cboe Options’ proposal to transition all of its European-style cashsettled options on the S&P 500 Index to A.M.-settlement; 11 however, in 1993, the Commission approved a rule allowing Cboe Options to list P.M.settled options on certain broad-based indices, including the S&P 500, expiring at the end of each calendar quarter (‘‘Quarterly Index Expirations’’) (since adopted as permanent).12 Starting in 6 The close of trading on the quarterly expiration Friday (i.e., the third Friday of March, June, September and December), when options, index futures, and options on index futures all expire simultaneously, became known as the ‘‘triple witching hour.’’ 7 See Securities and Exchange Commission, Division of Economic Risk and Analysis, Memorandum, Cornerstone Analysis of PM CashSettled Index Option Pilots (February 2, 2021) (‘‘DERA Staff PM Pilot Memo’’) at 5, available at: https://www.sec.gov/files/Analysis_of_PM_Cash_ Settled_Index_Option_Pilots.pdf. 8 The exercise settlement value for an A.M.settled index option is determined by reference to the reported level of the index as derived from the opening prices of the component securities on the business day before expiration. 9 See Securities Exchange Act Release No. 24367 (April 17, 1987), 52 FR 13890 (April 27, 1987) (SR– CBOE–87–11) (noting that CME moved S&P 500 futures contract’s settlement value to opening prices on the delivery date). 10 See id. 11 See Securities Exchange Act Release No. 30944 (July 21, 1992), 57 FR 33376 (July 28, 1992) (SR– CBOE–92–09). Thereafter, the Commission approved proposals by the options markets to transfer most of their cash-settled index products to A.M. settlement. 12 See Securities Exchange Act Release No. 31800 (February 1, 1993), 58 FR 7274 (February 5, 1993) (SR–CBOE–92–13); and see Rule 4.13(a)(2)(B); see also Securities Exchange Act Release Nos. 54123 PO 00000 Frm 00106 Fmt 4703 Sfmt 4703 2006, the Commission approved numerous rule changes, on a pilot basis, permitting the Cboe Options to introduce other index options, including SPX options, with P.M.settlement. These include P.M.-settled index options expiring weekly (other than the third Friday) and at the end of each month (‘‘EOM’’),13 P.M.-settled options on the S&P 500 Index that expire on the third Friday-of-the-month (‘‘SPXPM’’),14 as well as P.M.-settled Mini-SPX Index (‘‘XSP’’) options and Mini-Russell 2000 Index (‘‘MRUT’’) options expiring on the third Friday.15 As stated above, since its inception in 2010, the Exchange has continuously extended the FLEX PM Third Friday Pilot Program period and, during the course of the FLEX PM Third Friday Pilot Program and in support of the extensions of the FLEX PM Third Friday Pilot Program, the Exchange has submitted reports to the Commission regarding the Pilot Program that detail the Exchange’s experience with the Pilot Program, pursuant to the FLEX PM Third Friday Pilot Program.16 Specifically, the Exchange provided the Commission with annual reports analyzing volume and open interest for each broad-based FLEX Index Options class overlying a third Friday-of-themonth expiration day, p.m.-settled FLEX Index Options series. The annual reports also contained certain pilot period and pre-pilot period analyses of volume and open interest for third Friday-of-the-month expiration days, a.m.-settled FLEX Index series and third Friday-of-the-month expiration day Non-FLEX Index series overlying the (July 11, 2006), 71 FR 40558 (July 17, 2006) (SR– CBOE–2006–65); and 60164 (June 23, 2009), 74 FR 31333 (June 30, 2009) (SR–CBOE–2009–029). 13 See Securities Exchange Act Release Nos. 62911 (September 14, 2010), 75 FR 57539 (September 21, 2010) (SR–CBOE–2009–075); 76529 (November 30, 2015), 80 FR 75695 (December 3, 2015) (SR–CBOE–2015–106); 78132 (June 22, 2016), 81 FR 42018 (June 28, 2016) (SR–CBOE–2016–046); and 78531 (August 10, 2016), 81 FR 54643 (August 16, 2016) (SR–CBOE–2016–046). 14 See Securities Exchange Act Release No. 68888 (February 8, 2013), 78 FR 10668 (February 14, 2013) (SR–CBOE–2012–120) (the ‘‘SPXPM Approval Order’’). Pursuant to Securities Exchange Act Release No. 80060 (February 17, 2017), 82 FR 11673 (February 24, 2017) (SR–CBOE–2016–091), the Exchange moved third-Friday P.M.-settled options into the S&P 500 Index options class, and as a result, the trading symbol for P.M.-settled S&P 500 Index options that have standard third Friday-ofthe-month expirations changed from ‘‘SPXPM’’ to ‘‘SPXW.’’ This change went into effect on May 1, 2017, pursuant to Cboe Options Regulatory Circular RG17–054. 15 See Securities Exchange Act Release Nos. 70087 (July 31, 2013), 78 FR 47809 (August 6, 2013) (SR–CBOE–2013–055); and 91067 (February 5, 2021) 86 FR 9108 (February 11, 2021) (SR–CBOE– 2020–116). 16 See supra note 3.

The annual reports also contained information and analysis of FLEX Index Options trading patterns, and index price volatility and underlying share trading activity for each broad-based index class overlying an Expiration Friday, p.m.-settled FLEX Index Option that exceeds certain minimum open interest parameters. The Exchange also provided the Commission, on a periodic basis, interim reports of volume and open interest. Also, during the course of the FLEX PM Third Friday Pilot Program, the Exchange provided the Commission with any additional data or analyses the Commission requested if it deemed such data or analyses necessary to determine whether the Pilot Program was consistent with the Exchange Act. The Exchange has made public on its website all data and analyses previously submitted to the Commission under the FLEX PM Third Friday,17 and will continue to make public any data and analyses it submits to the Commission while the FLEX PM Third Friday is still in effect. The Exchange has concluded that the FLEX PM Third Friday does not negatively impact market quality or raise any unique or prohibitive regulatory concerns. The Exchange has not identified any evidence from the pilot data indicating that the trading of P.M.-settled FLEX options has any adverse impact on fair and orderly markets on Expiration Fridays for broadbased indexes or the underlying securities comprising those indexes, nor have there been any observations of abnormal market movements attributable to P.M.-settled FLEX options from any market participants that have come to the attention of the Exchange. Based on a study conducted by the Commission’s Division of Economic and Risk Analysis (‘‘DERA’’) staff on the pilot data from 2006 through 2018,18 and the Exchange’s review of the pilot data from 2019 through 2021, the size of 17 Available at https://www.cboe.com/aboutcboe/ legal-regulatory/national-market-system-plans/pmsettlement-spxpm-data. 18 See DERA Staff PM Pilot Memo, at 13 (‘‘Option settlement quantity data for A.M.- and P.M.-settled options were obtained from the Cboe, including the number of contracts that settled in-the-money for each exchange-traded option series on the S&P 500 index . . . on expiration days from January 20, 2006 through December 31, 2018. Daily open interest and volume data for [SPX] option series were also obtained from Cboe, including open interest data from January 3, 2006 through December 31, 2018 and trading volume data from January 3, 2006 through December 31, 2018.’’) VerDate Sep<11>2014 18:44 Apr 27, 2023 Jkt 259001 the market for P.M.-settled SPX options (including quarterly, weekly, EOM and third Friday expirations) since 2007 has grown from a trivial portion of the overall market to a substantial share (from around 0.1% of open interest in 2007 to 30% in 2021).19 Notional value of open interest in P.M.-settled SPX options increased from approximately a median of $1.5 billion in 2007 to $1.9 trillion in 2021, approximately 1260 times its value in 2007. Notional open interest in A.M.-settled SPX options was already hovering around a median of $1.4 trillion in 2007, and it has since increased to approximately $4.4 trillion in 2021. It is also important to note that open interest on expiring P.M.-settled SPX options, as compared to A.M.settled options, is spread out across a greater number of expiration dates, which results in a smaller percentage of open interest expiring on any one date, thus mitigating concerns that SPXPM option expiration may have a disruptive effect on the market.20 Daily trading volume in P.M.-settled SPX options has increased from a median of about 700 contracts in 2007 to nearly 1.9 million contracts in 2021,21 and now exceeds trading volume in A.M.-settled SPX options. Moreover, the DERA staff study of the P.M.-settled SPX options pilot data (2006 through 2018) did not identify any significant economic impact on S&P 500 futures,22 the S&P 500, or the underlying component securities of the S&P 500 surrounding the close. For purposes of the study, volatility was by and large measured by using the standard deviation 23 of one-minute returns of S&P 500 futures values and the index value during regular hours on each day reviewed (excluding the first and last 15 minutes of trading) and then 19 The DERA staff study reviewed and provided statistics for market share, median notional value of open interest and median volume in 2007 and in 2018. The Exchange provides updated statistics for market share, median notional value of open interest and median volume in 2021, replacing the 2018 statistics provided in the Commission staff study. 20 See DERA Staff PM Pilot Memo, at 2. 21 The Exchange notes that the DERA staff study used two-sided volume data for the median volume in 2007 and in 2018; therefore, the Exchange provides two-sided volume data for the median volume in 2021. 22 Futures on the S&P 500 experience high volume and liquidity both before and after the close of the underlying market. Therefore, futures are a useful measure of abnormal volatility surrounding the close and the open. See DERA Staff PM Pilot Memo, at 14. The Exchange agrees with this approach. 23 Standard deviation applied to a rate of return (in this case, one-minute) of an instrument can indicate that instrument’s historical volatility. The greater the standard deviation, the greater the variance between price and the mean, which indicates a larger price range, i.e., higher volatility. PO 00000 Frm 00107 Fmt 4703 Sfmt 4703 26355 compared with the standard deviation of one-minute returns (for S&P 500 futures, the S&P 500, and the underlying component securities of the S&P 500) over the last 15 minutes of a trading day.24 Using this as a general measure,25 the DERA staff study then reviewed whether, and to what extent, the settlement quantity of SPXPM options and the levels of open interest in SPXPM options on expiration days (as compared to non-expiration days) may be associated with general price volatility and price reversals for S&P 500 futures, the S&P 500, and the underlying component securities of the S&P 500 near the close. From its review of the study, the Exchange agrees that, although volatility before the market close is generally higher than during the rest of the trading day, there is no evidence of any significant adverse economic impact to the futures, index, or underlying index component securities markets as a result of the quantity of P.M.-settled SPX options that settle at the close or the amount of expiring open interest in P.M.-settled SPX options. For example, the largest settlement event that occurred during the time period of the study (a settlement of $100.4 billion of notional on December 29, 2017) had an estimated impact on the futures price of only approximately 0.02% (a predicted impact of $0.54 relative to a closing futures price of $2,677). In particular, the DERA staff study found that an additional P.M.-settled SPX options settlement quantity equal to $10 billion in notional value is associated with a marginal impact on futures prices during the last 15 minutes of the trading day of only about $0.06 (where the hypothetical index level is 2,500), additional expiring open interest in P.M.-settled SPX options equal to $10 billion in notional value is associated with a marginal impact on futures prices during the last 15 minutes of the trading day of only about $0.05 (assumed index level is 2,500). Also, an additional 24 For example, if on a particular day the standard deviation of one-minute returns between 3:45 p.m. ET and 4:00 p.m. ET is 0.004 and the standard deviation of returns from 9:45 a.m. ET to 3:45 p.m. ET is 0.002, this metric would take on a value of 2 for that day, indicating that volatility during the last 15 minutes of the trading day was twice as high as it was during the rest of the trading day. See DERA Staff PM Pilot Memo, at 15; see also DERA Staff PM Pilot Memo, at Section V, which discusses in detail the metrics used to measure, for the purposes of the study, the extent to which the market may experience abnormal volatility surrounding SPXPM option settlement. 25 See DERA Staff PM Pilot Memo, at Section V, which discusses in detail the metrics used to measure, for the purposes of the study, the extent to which the market may experience abnormal volatility surrounding SPXPM option settlement.

Likewise, the study identified that an additional total P.M.-settled SPX options settlement quantity equal to $10 billion in notional value corresponds to price movement in the S&P 500 of only about $0.08 (assuming an index level of 2,500) during the last 15 minutes of the trading day, and that additional expiring open interest equal to $10 billion in notional value corresponds to a price movement in the S&P 500 of only about $0.06 (assuming an index level of 2,500) during the last 15 minutes of the trading day. The study also identified that it would take an increase of $34 billion in notional value of total settlement quantity and of expiring open interest for one additional S&P 500 price reversal of greater than two standard deviations to occur in the last 15 minutes before the market close. Also, regarding potential impact to S&P 500 component securities, it would take an increase in total P.M.-settled SPX options settlement quantity equal to $20 billion to effect a price movement of only approximately $0.03 for a $200 stock, an increase in expiring open interest in P.M.-settled SPX options equal to $10 billion to effect a price movement less than half a standard deviation, and an increase in total P.M.settled SPX settlement quantity equal to $7 billion to achieve a price reversal greater two standard deviations. The study employed the same metrics to determine whether there is greater price volatility for S&P 500 futures, the S&P 500, and the component securities of the S&P 500 related to SPXPM option settlements during an environment of high market volatility (i.e., on days in which the VIX Index was in the top 10% of closing index values) and did not identify indicators of any significant economic impact on these markets near the close as a result of the P.M.-settled SPX options settlement.27 In addition to this, the DERA staff study, applying the same metrics and analysis as for P.M.settled SPX options to A.M.-settled SPX options, did not identify any evidence of a statistically significant relationship between settlement quantity or expiring 26 See supra note 22. Exchange also notes that the study did not identify any evidence that less liquid S&P 500 constituent securities experienced any greater impact from the settlement of P.M.-settled SPX options. 27 The VerDate Sep<11>2014 18:44 Apr 27, 2023 Jkt 259001 open interest of A.M.-settled options and volatility near the open. Upon review of the results of the DERA staff study, the Exchange agrees that each of the above-described marginal price movements in S&P 500 futures, the S&P 500, and the S&P 500 component securities affected by increases in P.M.-settled SPX options settlement quantity and expiring open interest appear to be de minimis pricing changes from those that occur over regular trading hours (outside of the last 15 minutes of the trading day). Further, the Exchange has not observed any significant economic impact or other adverse effects on the market from similar reviews of its pilot reports and data submitted after 2018.28 In its review of a sample of the pilot data from 2019 through 2021, the Exchange similarly measured volatility over the final fifteen minutes of each trading day by taking the standard deviation of rolling one-minute returns of the S&P 500 level (excluding the first and last fifteen minutes of trading) and comparing such with the standard deviation of one-minute returns 29 of the S&P 500 level, over the last 15 minutes of a trading day. The Exchange identified an average standard deviation ratio of 1.42 for the S&P 500 on nonexpiration days and an average standard deviation ratio of 1.54 for the S&P 500 on expiration days (a ratio between expiration days and non-expiration days of 1.09). The Exchange also notes that, using the same methodology, it observed that, from 2015 through 2019,30 the average standard deviation ratio for the S&P 500 on non-expiration days was 1.11 and the average standard deviation ratio for the S&P 500 on expiration days was 1.22 (a ratio between expiration days and nonexpiration days of 1.10). While the average standard deviation ratio on both expiration and non-expiration days was higher in 2019 through 2021 due to overall market volatility, the ratios between the standard deviation ratios on expiration days and non-expirations days remained nearly identical between the 2015 through 2019 timeframe and the 2019 through 2021. This shows that, in cases where overall market volatility may increase, the normalized impact on expiration days to non-expiration days generally remains consistent. In addition to this, the Exchange notes that the S&P 500 is rebalanced quarterly. The changes resulting from each 28 Total SPX open interest volumes were examined for expiration dates over a roughly twoyear period between October 2019 and November 2021. 29 Calculated at every tick for the prior minute. 30 November 2015 through November 2021. PO 00000 Frm 00108 Fmt 4703 Sfmt 4703 rebalancing coincide with the thirdFriday of the quarterly rebalancing month (i.e., March, June, September, October and December) 31 and generally drive an increase in trading activity from investors that seek to track the S&P 500. As such, the Exchange measured volatility on quarterly rebalancing dates and found that the average standard deviation ratio was 1.62, which suggests more closing volatility on quarterly rebalance dates compared to nonquarterly expiration dates (for which the average standard deviation ratio was 1.22), thus indicating that the impact rebalancing may have on the S&P 500 is greater than any impact that P.M.-settled SPX options may have on the S&P 500. The Exchange additionally focused its study of the post-2018 sample pilot data on reviewing for potential correlation between excess market volatility and price reversals and the hedging activity of liquidity providers. As explained in the DERA staff study, potential impact of P.M.-settled SPX options on the correlated equity markets is thought to stem from the hedging activity of liquidity providers in such options.32 To determine any such potential correlation, the Exchange studied the expected action of liquidity providers that are the primary source of the hedging on settlement days. These liquidity providers generally deltahedge their S&P 500 index exposure via S&P 500 futures and on settlement day unwind their futures positions that correspond with the delta of their inthe-money (ITM) expiring P.M.-settled SPX options. Assuming such behavior, the Exchange estimated the Market-OnClose (‘‘MOC’’) 33 volume for the shares of the S&P 500 component securities (i.e., ‘‘MOC share volume’’) that could ultimately result from the unwinding of the liquidity providers’ futures positions by equating the notional value of the futures positions that correspond to expiring ITM open interest to the number S&P 500 component security contracts (based on the weight of each S&P 500 component security). That is, the Exchange calculated (an estimate) of the amount of MOC volume in the S&P 500 component markets attributable hedging activity as a result of expiring ITM P.M.-settled SPX options (i.e., ‘‘hedging MOC’’). The Exchange then: 31 See S&P Dow Jones Indices, Equity Indices Policies & Practices, Methodology (August 2021), at 15, available at https://www.spglobal.com/spdji/en/ documents/methodologies/methodology-sp-equityindices-policies-practices.pdf. 32 See DERA Staff PM Pilot Memo, at 10–12. 33 MOC orders allow a market participant to trade at the closing price. Market participants generally utilize MOC orders to ensure they exit positions at the end of the trading day. E:\FR\FM\28APN1.SGM 28APN1 ddrumheller on DSK120RN23PROD with NOTICES1 Federal Register / Vol. 88, No. 82 / Friday, April 28, 2023 / Notices (1) compared the hedging MOC share volume to all MOC share volume on expiration days and non-expiration trading days; and (2) compared the notional value of the hedging futures positions (i.e., that correspond to expiring ITM P.M.-settled SPX options open interest) to the notional value of expiring ITM P.M.-settled SPX options open interest, the notional value of all expiring P.M.-settled SPX options open interest and the notional value of all P.M.-settled SPX options open interest. The Exchange observed that, on average, there were approximately 25% more MOC shares executed on expiration days (332 expiration days) than non-expiration days (209 nonexpiration days). While, at first glance, the volume of MOC shares executed on expiration days seems much greater than the volume executed on nonexpiration days, the Exchange notes that much of this difference is attributable to just eight expiration days—the quarterly index rebalancing dates captured within the scope of the post-2018 sample pilot data. The average MOC share volume on the eight quarterly rebalancing dates was approximately 4.8 times the average MOC share volume on the non-quarterly rebalancing expiration dates; again, indicating that the impact rebalancing may have on the S&P 500 Index is greater than any impact that P.M.-settled SPX options may have on the S&P 500 Index. That is, the Exchange observed that the majority of closing volume on quarterly rebalance dates is driven by rebalancing of shares in in the S&P 500, and not by P.M.-settled SPX options expiration-related hedging activity. Notwithstanding the MOC share volume on quarterly rebalancing dates, the volume of MOC shares executed on expiration days (324 expiration days) was only approximately 13% more than that on non-expiration days, substantially less than the increase in volume over non-expiration days wherein the eight index rebalancing dates are included in expiration day volume. In addition to this, the Exchange observed that the hedging MOC share volume (i.e., the expected MOC share volume resulting from hedging activity in connection with expiring ITM P.M.-settled SPX options) was, on average, less than the MOC share volume on non-expiration days, and was only approximately 20% of the total MOC share volume on expiration days, indicating that other sources of MOC share volume generally exceed the volume resulting from hedging activity of expiring ITM P.M.-settled SPX options and would more likely be a source of any potential market volatility. VerDate Sep<11>2014 18:44 Apr 27, 2023 Jkt 259001 The Exchange also observed that, across all third-Friday expirations, the notional value of the hedging futures positions was approximately 25% of the notional value of expiring ITM P.M.settled SPX options, approximately 3.8% of the notional value of all expiring P.M.-settled SPX options, and approximately only 0.5% of the notional value of all P.M.-settled SPX options. As such, the estimated hedging activity from liquidity providers on expiration days is a fraction of the expiring open interest in P.M.-settled SPX options, which, the Exchange notes, is only 14% of the total open interest in P.M.-settled SPX options; thus, indicating negligible capacity for hedging activity to increase volatility in the underlying markets. While unrelated to the initial concerns of P.M.-settlement as described above, at the request of the Commission, the Exchange recently completed an analysis intended to evaluate whether the introduction of P.M.-settled options impacted the quality of the A.M.-settled option market. Specifically, the Exchange compared values of key market quality indicators (specifically, the bid-ask spread 34 and effective spread 35) in SPXW options both before and after the introduction of Tuesday expirations and Thursday expirations for SPXW options on April 18 and May 11, 2022, respectively.36 Options on the Standard & Poor’s Depositary Receipts S&P 500 ETF (‘‘SPY’’) were used as a control group to account for any market factors that might influence key market quality indicators. The Exchange used data from January 3, 2022 through March 4, 2022 (the two-month period prior to the introduction of SPXW options with Tuesday expirations) and data from May 11, 2022 to July 10, 2022 (the twomonth period following the 34 The Exchange calculated for each of SPXW options (with Monday, Wednesday, and Friday expirations) and SPY Weekly options (with Monday, Wednesday, and Friday expirations) the daily time-weighted bid-ask spread on the Exchange during its regular trading hours session, adjusted for the difference in size between SPXW options and SPY options (SPXW options are approximately ten times the value of SPY options). 35 The Exchange calculated the volume-weighted average daily effective spread for simple trades for each of SPXW options (with Monday, Wednesday, and Friday expirations) and SPY Weekly options (with Monday, Wednesday, and Friday expirations) as twice the amount of the absolute value of the difference between an order execution price and the midpoint of the national best bid and offer at the time of execution, adjusted for the difference in size between SPXW options and SPY options. 36 For purposes of comparison, the Exchange paired SPXW options and SPY options with the same moneyness and same days to expiration. PO 00000 Frm 00109 Fmt 4703 Sfmt 4703 26357 introduction of SPXW options with Thursday expirations).37 Given the time that as passed since the introduction of FLEX P.M.-settled options, the Exchange is unable to analyze whether the introduction of those options significantly impacted the market quality of FLEX P.M.-settled options. Additionally, the Exchange is unable to analyze whether the introduction of the FLEX P.M.-settled options significantly impacted the market quality of A.M.-settled FLEX options, as there is no book for FLEX options, as FLEX options are listed only if and when market participants create them for trading. However, the Exchange believes analyzing whether the introduction of new SPXW P.M.settled expirations (i.e., SPXW options with Tuesday and Thursday expirations) impacted the market quality of then-existing SPXW P.M.settled expirations (i.e., SPXW options with Monday, Wednesday, and Friday expirations) provides a reasonable substitute to evaluate whether the introduction of P.M.-settled index options impacted the market quality of the underlying cash markets when the pilot began. The full analysis is included in Exhibit 3 of this rule filing. As a result of this analysis, the Exchange believes the introduction of SPX options with Tuesday and Thursday options had no significant impact on the market quality of SPXW options with Monday, Wednesday, and Friday expirations. With respect to the majority of series analyzed, the Exchange observed no statistically significant difference in the bid-ask spread or the effective spread of the series in the period prior to introduction of the Tuesday and Thursday expirations and the period following the introduction of the Tuesday and Thursday expirations. While statistically insignificant, the Exchange notes that in many series, particularly as they were closer to expiration, the Exchange observed that the values of these spreads decreased during the period following the introduction of the Tuesday and Thursday expirations.38 To further note, given the significant changes in the closing procedures of the primary markets in recent decades, including considerable advances in trading systems and technology, the Exchange believes that the risks of any potential impact of P.M.-, cash-settled 37 The Exchange observed comparable market volatility levels during the pre-intervention and post-intervention time ranges. 38 In any series in which the Exchange observed an increase in the market quality indicators, the Exchange notes any such increase was also statistically insignificant.

The Exchange proposes to make the FLEX PM Third Friday Program permanent as P.M.-settled index products have become an integral part of the Exchange’s product offerings, providing investors with greater trading opportunities and flexibility. As indicated by the significant growth in the size of the market for P.M.-settled options, such options have been, and continue to be, well-received and widely used by market participants. Therefore, the Exchange wishes to be able to continue to provide investors with the ability to trade FLEX PM options on a permanent basis. The Exchange believes that the permanent continuation of the FLEX PM Third Friday Pilot Program will serve to maintain the status quo by continuing to offer a product to which investors have become accustomed and have incorporated into their business models and day-to-day trading methodologies for nearly ten years. As such, the Exchange also believes that ceasing to offer FLEX PM options may result in significant market disruption and investor confusion. The Exchange has not identified any significant impact on market quality nor any unique or prohibitive regulatory concerns as a result of the FLEX PM Third Friday Pilot Program, and, as such, the Exchange believes that the continuation of the FLEX PM Third Friday Pilot Program as a pilot, including the use of time and resources to compile and analyze quarterly and annual pilot reports and pilot data, is no longer necessary and that making the FLEX PM Third Friday Pilot Program permanent will allow the Exchange to otherwise allocate time and resources to other industry initiatives. 2. Statutory Basis The Exchange believes the proposed rule change is consistent with the Securities Exchange Act of 1934 (the ‘‘Act’’) and the rules and regulations thereunder applicable to the Exchange and, in particular, the requirements of section 6(b) of the Act.39 Specifically, the Exchange believes the proposed rule change is consistent with the section 6(b)(5) 40 requirements that the rules of an exchange be designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to, 39 15 40 15 U.S.C. 78f(b). U.S.C. 78f(b)(5). VerDate Sep<11>2014 18:44 Apr 27, 2023 and facilitating transactions in securities, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general, to protect investors and the public interest. In particular, the Exchange believes that the making the FLEX PM Third Friday Pilot Program permanent will allow the Exchange to be able to continue to offer FLEX PM options on a continuous and permanent basis. These products have been, and continue to be, well-received and widely used by market participants, providing investors with greater trading opportunities and flexibility. The Exchange believes that the permanent continuation of the FLEX PM Third Friday Pilot Program will remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general, protect investors and the public interest by continuing to offer a product to which investors have become accustomed and have incorporated into their business models and day-to-day trading strategies for approximately 13 years. The Exchange believes ceasing to offer the FLEX PM Third Friday Pilot Program may result in significant market disruption and investor confusion, as P.M.-settled index products, particularly SPX options, have become an integral part of the Exchange’s product offerings, providing investors with greater trading opportunities and flexibility. The Exchange further believes that making the FLEX PM Third Friday Pilot Program permanent will remove impediments to and perfect the mechanism of a free and open market and a national market system and protect investors, while maintaining a fair and orderly market, as the Exchange believes that previous concerns (arising in the 1980s) regarding options expirations potentially contributing to excess volatility and reversals around the close have been adequately diminished. As described in detail above, the Exchange has observed no significant adverse market impact or identified any meaningful regulatory concerns during the approximately 13year operation of the FLEX PM Third Friday Program as a pilot nor during the 15 years since P.M.-settled index options (SPX) were reintroduced to the marketplace.41 Notably, the Exchange did not identify any significant economic impact (including on pricing or volatility or in connection with reversals) on related futures, the underlying indexes, or the underlying component securities of the underlying 41 See Jkt 259001 PO 00000 supra notes 18–31. Frm 00110 Fmt 4703 Sfmt 4703 indexes surrounding the close as a result of the quantity of P.M.-settled FLEX options that settle at the close or the amount of expiring open interest in P.M.-settled FLEX options, nor any demonstrated capacity for options hedging activity to impact volatility in the underlying markets. While the DERA staff study and corresponding Exchange study described above specifically evaluated SPX options, P.M.-settled FLEX options overlay broad-based indexes (including the S&P 500), the Exchange believes it is appropriate to extrapolate the data to apply the FLEX PM options. This is particularly true given that the reports submitted by the Exchange during the pilot period have similarly demonstrated no significant economic impact on the respective underlying indexes or other products. The Exchange also believes the introduction of FLEX PM options had no significant impact on the market quality of corresponding A.M.-settled options or other options. The Exchange believes this as a result of its analysis conducted after the introduction of SPXW options with Tuesday and Thursday expirations, which demonstrated no statistically significant impact on the bid-ask or effective spreads of SPXW options with Monday, Wednesday, and Friday expirations after trading in the SPXW options with Tuesday and Thursday expirations began. FLEX options are nearly identical to non-FLEX options and overlay the same indexes. Therefore, the Exchange believes analyzing the impact of new SPXW options on then-existing SPXW options permit the Exchange to extrapolate from this data that it is unlikely the introduction of P.M.-settled FLEX options significantly impacted the market quality of A.M.-settled options when the pilot began. Additionally, the significant changes in the closing procedures of the primary markets in recent decades, including considerable advances in trading systems and technology, has significantly minimized risks of any potential impact of P.M.-, cash-settled FLEX options on the underlying cash markets. As such, the Exchange believes that a permanent FLEX PM Third Friday Pilot Program does not raise any unique or prohibitive regulatory concerns and that such trading has not, and will not, adversely impact fair and orderly markets on Expiration Fridays for the underlying indexes or their component securities. Further, as the Exchange has not identified any significant impact on market quality or any unique or prohibitive regulatory concerns as a result of offering FLEX PM options, the E:\FR\FM\28APN1.SGM 28APN1 Federal Register / Vol. 88, No. 82 / Friday, April 28, 2023 / Notices ddrumheller on DSK120RN23PROD with NOTICES1 Exchange believes that the continuation of the FLEX PM Third Friday Pilot Program as a pilot, including the gathering, submission and review of the pilot reports and data, is no longer necessary and that making the FLEX PM Third Friday Pilot Program permanent will allow the Exchange to otherwise allocate time and resources to other industry initiatives. B. Self-Regulatory Organization’s Statement on Burden on Competition Cboe Options does not believe that the proposed rule change will impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. The Exchange does not believe that making the FLEX PM Third Friday Pilot Program permanent will impose any unnecessary or inappropriate burden on intramarket competition because FLEX PM options will continue to be available to all market participants who wish to participate in the FLEX PM options market. The Exchange believes that the growth that the P.M.-settled options market, including FLEX PM options, has experienced since their reintroduction through pilot programs indicates strong, continued investor interest and demand, warranting a permanent FLEX PM Third Friday Pilot Program. The Exchange believes that, for the period that P.M.settled FLEX options have been in operation as pilot programs, they have provided investors with a desirable product with which to trade and wishes to permanently offer this product to investors. Furthermore, during the pilot period, the Exchange has not observed any significant adverse market effects nor identified any regulatory concerns as a result of the FLEX PM Third Friday Pilot Program, and, as such, the continuation of the FLEX PM Third Friday Pilot Program as a pilot, including the gathering, submission and review of the pilot reports and data, is no longer necessary—a permanent FLEX PM Third Friday Pilot Program will allow the Exchange to otherwise allocate time and resources to other industry initiatives. The Exchange further does not believe that making the FLEX PM Third Friday Pilot Program permanent will impose any burden on intermarket competition that is not necessary or appropriate in furtherance of the purposes of the Act because it applies to a class of options listed only for trading on Cboe Options. The Exchange notes that other exchanges are free to and do offer competing products. To the extent that the permanent offering and continued trading of FLEX PM options may make Cboe Options a more attractive VerDate Sep<11>2014 18:44 Apr 27, 2023 Jkt 259001 marketplace to market participants at other exchanges, such market participants may elect to become Cboe Options market participants. C. Self-Regulatory Organization’s Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others The Exchange neither solicited nor received comments on the proposed rule change. III.

II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the Exchange included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. The Exchange has prepared summaries, set forth in 
sections A, B, and C below, of the most significant aspects of such 
statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange proposes to make permanent its Pilot Program that 
permits the Exchange to list FLEX Options whose exercise settlement 
value is derived from closing prices on the last trading day prior to 
expiration that expire on or within two business days of a third 
Friday-of-the-month expiration day for a non-FLEX Option (other than 
QIX options) (``FLEX PM Third Friday''). The Securities and Exchange 
Commission (the ``Commission'') approved a Cboe Options rule change 
that, among other things, established a pilot program regarding 
permissible exercise settlement values for FLEX Index

period numerous times, which is currently set to expire on the earlier 
of May 8, 2023 or the date on which the pilot program is approved on a 
permanent basis.\4\ The Exchange hereby requests that the Commission 
approve the FLEX PM Third Friday Pilot Program on a permanent basis.

eliminating the minimum value size requirements was extended twice 
pursuant to the same rule filings that extended the permissible 
exercise settlement values (for the same extended periods) and was 
approved on a permanent basis in a separate rule change filing. See 
id; and Securities Exchange Act Release No. 67624 (August 8, 2012),

---------------------------------------------------------------------------

    By way of background, when cash-settled \5\ index options were 
first introduced in the 1980s, settlement was based on the closing 
value of the underlying index on the option's expiration date. The 
Commission later became concerned about the impact of P.M.-settled, 
cash-settled index options on the markets for the underlying stocks at 
the close on expiration Fridays. Specifically, certain episodes of 
price reversals around the close on quarterly expiration dates 
attracted the attention of regulators to the possibility that the 
simultaneous expiration of index futures, futures options, and options 
might be inducing abnormal volatility in the index value around the 
close.\6\ Academic research at the time provided at least some evidence 
suggesting that futures and options expirations contributed to excess 
volatility and reversals around the close on those days.\7\ In light of 
the concerns with P.M.-settlement and to help ameliorate the price 
effects associated with expirations of P.M.-settled, cash-settled index 
products, in 1987, the Commodity Futures Trading Commission (``CFTC'') 
approved a rule change by the Chicago Mercantile Exchange (``CME'') to 
provide for A.M. settlement \8\ for index futures, including futures on 
the S&P 500.\9\ The Commission subsequently approved a rule change by 
Cboe Options to list and trade A.M.-settled SPX options.\10\ In 1992, 
the Commission approved Cboe Options' proposal to transition all of its 
European-style cash-settled options on the S&P 500 Index to A.M.-
settlement; \11\ however, in 1993, the Commission approved a rule 
allowing Cboe Options to list P.M.-settled options on certain broad-
based indices, including the S&P 500, expiring at the end of each 
calendar quarter (``Quarterly Index Expirations'') (since adopted as 
permanent).\12\ Starting in 2006, the Commission approved numerous rule 
changes, on a pilot basis, permitting the Cboe Options to introduce 
other index options, including SPX options, with P.M.-settlement. These 
include P.M.-settled index options expiring weekly (other than the 
third Friday) and at the end of each month (``EOM''),\13\ P.M.-settled 
options on the S&P 500 Index that expire on the third Friday-of-the-
month (``SPXPM''),\14\ as well as P.M.-settled Mini-SPX Index (``XSP'') 
options and Mini-Russell 2000 Index (``MRUT'') options expiring on the 
third Friday.\15\
---------------------------------------------------------------------------

    \5\ The seller of a ``cash-settled'' index option pays out the 
cash value of the applicable index on expiration or exercise. A 
``physically settled'' option, like equity and ETF options, involves 
the transfer of the underlying asset rather than cash. See 
Characteristics and Risks of Standardized Options, available at: 
https://www.theocc.com/Company-Information/Documents-and-Archives/Options-Disclosure-Document.
    \6\ The close of trading on the quarterly expiration Friday 
(i.e., the third Friday of March, June, September and December), 
when options, index futures, and options on index futures all expire 
simultaneously, became known as the ``triple witching hour.''

Risk and Analysis, Memorandum, Cornerstone Analysis of PM Cash-

    \8\ The exercise settlement value for an A.M.-settled index 
option is determined by reference to the reported level of the index 
as derived from the opening prices of the component securities on 
the business day before expiration.

---------------------------------------------------------------------------

    As stated above, since its inception in 2010, the Exchange has 
continuously extended the FLEX PM Third Friday Pilot Program period 
and, during the course of the FLEX PM Third Friday Pilot Program and in 
support of the extensions of the FLEX PM Third Friday Pilot Program, 
the Exchange has submitted reports to the Commission regarding the 
Pilot Program that detail the Exchange's experience with the Pilot 
Program, pursuant to the FLEX PM Third Friday Pilot Program.\16\ 
Specifically, the Exchange provided the Commission with annual reports 
analyzing volume and open interest for each broad-based FLEX Index 
Options class overlying a third Friday-of-the-month expiration day, 
p.m.-settled FLEX Index Options series. The annual reports also 
contained certain pilot period and pre-pilot period analyses of volume 
and open interest for third Friday-of-the-month expiration days, a.m.-
settled FLEX Index series and third Friday-of-the-month expiration day 
Non-FLEX Index series overlying the

[[Page 26355]]

same index as a third Friday-of-the-month expiration day, p.m.-settled 
FLEX Index option. The annual reports also contained information and 
analysis of FLEX Index Options trading patterns, and index price 
volatility and underlying share trading activity for each broad-based 
index class overlying an Expiration Friday, p.m.-settled FLEX Index 
Option that exceeds certain minimum open interest parameters. The 
Exchange also provided the Commission, on a periodic basis, interim 
reports of volume and open interest.
---------------------------------------------------------------------------

    \16\ See supra note 3.
---------------------------------------------------------------------------

    Also, during the course of the FLEX PM Third Friday Pilot Program, 
the Exchange provided the Commission with any additional data or 
analyses the Commission requested if it deemed such data or analyses 
necessary to determine whether the Pilot Program was consistent with 
the Exchange Act. The Exchange has made public on its website all data 
and analyses previously submitted to the Commission under the FLEX PM 
Third Friday,\17\ and will continue to make public any data and 
analyses it submits to the Commission while the FLEX PM Third Friday is 
still in effect.

    \17\ Available at https://www.cboe.com/aboutcboe/legal-regulatory/national-market-system-plans/pm-settlement-spxpm-data.
---------------------------------------------------------------------------

    The Exchange has concluded that the FLEX PM Third Friday does not 
negatively impact market quality or raise any unique or prohibitive 
regulatory concerns. The Exchange has not identified any evidence from 
the pilot data indicating that the trading of P.M.-settled FLEX options 
has any adverse impact on fair and orderly markets on Expiration 
Fridays for broad-based indexes or the underlying securities comprising 
those indexes, nor have there been any observations of abnormal market 
movements attributable to P.M.-settled FLEX options from any market 
participants that have come to the attention of the Exchange.
    Based on a study conducted by the Commission's Division of Economic 
and Risk Analysis (``DERA'') staff on the pilot data from 2006 through 
2018,\18\ and the Exchange's review of the pilot data from 2019 through 
2021, the size of the market for P.M.-settled SPX options (including 
quarterly, weekly, EOM and third Friday expirations) since 2007 has 
grown from a trivial portion of the overall market to a substantial 
share (from around 0.1% of open interest in 2007 to 30% in 2021).\19\ 
Notional value of open interest in P.M.-settled SPX options increased 
from approximately a median of $1.5 billion in 2007 to $1.9 trillion in 
2021, approximately 1260 times its value in 2007. Notional open 
interest in A.M.-settled SPX options was already hovering around a 
median of $1.4 trillion in 2007, and it has since increased to 
approximately $4.4 trillion in 2021. It is also important to note that 
open interest on expiring P.M.-settled SPX options, as compared to 
A.M.-settled options, is spread out across a greater number of 
expiration dates, which results in a smaller percentage of open 
interest expiring on any one date, thus mitigating concerns that SPXPM 
option expiration may have a disruptive effect on the market.\20\ Daily 
trading volume in P.M.-settled SPX options has increased from a median 
of about 700 contracts in 2007 to nearly 1.9 million contracts in 
2021,\21\ and now exceeds trading volume in A.M.-settled SPX options.
---------------------------------------------------------------------------

    \18\ See DERA Staff PM Pilot Memo, at 13 (``Option settlement 
quantity data for A.M.- and P.M.-settled options were obtained from 
the Cboe, including the number of contracts that settled in-the-
money for each exchange-traded option series on the S&P 500 index . 
. . on expiration days from January 20, 2006 through December 31, 
2018. Daily open interest and volume data for [SPX] option series 
were also obtained from Cboe, including open interest data from 
January 3, 2006 through December 31, 2018 and trading volume data 
from January 3, 2006 through December 31, 2018.'')
    \19\ The DERA staff study reviewed and provided statistics for 
market share, median notional value of open interest and median 
volume in 2007 and in 2018. The Exchange provides updated statistics 
for market share, median notional value of open interest and median 
volume in 2021, replacing the 2018 statistics provided in the 
Commission staff study.
    \20\ See DERA Staff PM Pilot Memo, at 2.
    \21\ The Exchange notes that the DERA staff study used two-sided 
volume data for the median volume in 2007 and in 2018; therefore, 
the Exchange provides two-sided volume data for the median volume in 
2021.
---------------------------------------------------------------------------

    Moreover, the DERA staff study of the P.M.-settled SPX options 
pilot data (2006 through 2018) did not identify any significant 
economic impact on S&P 500 futures,\22\ the S&P 500, or the underlying 
component securities of the S&P 500 surrounding the close. For purposes 
of the study, volatility was by and large measured by using the 
standard deviation \23\ of one-minute returns of S&P 500 futures values 
and the index value during regular hours on each day reviewed 
(excluding the first and last 15 minutes of trading) and then compared 
with the standard deviation of one-minute returns (for S&P 500 futures, 
the S&P 500, and the underlying component securities of the S&P 500) 
over the last 15 minutes of a trading day.\24\ Using this as a general 
measure,\25\ the DERA staff study then reviewed whether, and to what 
extent, the settlement quantity of SPXPM options and the levels of open 
interest in SPXPM options on expiration days (as compared to non-
expiration days) may be associated with general price volatility and 
price reversals for S&P 500 futures, the S&P 500, and the underlying 
component securities of the S&P 500 near the close. From its review of 
the study, the Exchange agrees that, although volatility before the 
market close is generally higher than during the rest of the trading 
day, there is no evidence of any significant adverse economic impact to 
the futures, index, or underlying index component securities markets as 
a result of the quantity of P.M.-settled SPX options that settle at the 
close or the amount of expiring open interest in P.M.-settled SPX 
options. For example, the largest settlement event that occurred during 
the time period of the study (a settlement of $100.4 billion of 
notional on December 29, 2017) had an estimated impact on the futures 
price of only approximately 0.02% (a predicted impact of $0.54 relative 
to a closing futures price of $2,677).
---------------------------------------------------------------------------

    \22\ Futures on the S&P 500 experience high volume and liquidity 
both before and after the close of the underlying market. Therefore, 
futures are a useful measure of abnormal volatility surrounding the 
close and the open. See DERA Staff PM Pilot Memo, at 14. The 
Exchange agrees with this approach.
    \23\ Standard deviation applied to a rate of return (in this 
case, one-minute) of an instrument can indicate that instrument's 
historical volatility. The greater the standard deviation, the 
greater the variance between price and the mean, which indicates a 
larger price range, i.e., higher volatility.
    \24\ For example, if on a particular day the standard deviation 
of one-minute returns between 3:45 p.m. ET and 4:00 p.m. ET is 0.004 
and the standard deviation of returns from 9:45 a.m. ET to 3:45 p.m. 
ET is 0.002, this metric would take on a value of 2 for that day, 
indicating that volatility during the last 15 minutes of the trading 
day was twice as high as it was during the rest of the trading day. 
See DERA Staff PM Pilot Memo, at 15; see also DERA Staff PM Pilot 
Memo, at Section V, which discusses in detail the metrics used to 
measure, for the purposes of the study, the extent to which the 
market may experience abnormal volatility surrounding SPXPM option 
settlement.
    \25\ See DERA Staff PM Pilot Memo, at Section V, which discusses 
in detail the metrics used to measure, for the purposes of the 
study, the extent to which the market may experience abnormal 
volatility surrounding SPXPM option settlement.
---------------------------------------------------------------------------

    In particular, the DERA staff study found that an additional P.M.-
settled SPX options settlement quantity equal to $10 billion in 
notional value is associated with a marginal impact on futures prices 
during the last 15 minutes of the trading day of only about $0.06 
(where the hypothetical index level is 2,500), additional expiring open 
interest in P.M.-settled SPX options equal to $10 billion in notional 
value is associated with a marginal impact on futures prices during the 
last 15 minutes of the trading day of only about $0.05 (assumed index 
level is 2,500). Also, an additional

[[Page 26356]]

increase in settlement quantity or in expiring open interest, each 
equal to $20 million in notional value, did not result in any 
meaningful futures price reversals near the close (neither was found to 
cause a price reversal of over one standard deviation \26\).
---------------------------------------------------------------------------

    \26\ See supra note 22.
---------------------------------------------------------------------------

    Likewise, the study identified that an additional total P.M.-
settled SPX options settlement quantity equal to $10 billion in 
notional value corresponds to price movement in the S&P 500 of only 
about $0.08 (assuming an index level of 2,500) during the last 15 
minutes of the trading day, and that additional expiring open interest 
equal to $10 billion in notional value corresponds to a price movement 
in the S&P 500 of only about $0.06 (assuming an index level of 2,500) 
during the last 15 minutes of the trading day. The study also 
identified that it would take an increase of $34 billion in notional 
value of total settlement quantity and of expiring open interest for 
one additional S&P 500 price reversal of greater than two standard 
deviations to occur in the last 15 minutes before the market close. 
Also, regarding potential impact to S&P 500 component securities, it 
would take an increase in total P.M.-settled SPX options settlement 
quantity equal to $20 billion to effect a price movement of only 
approximately $0.03 for a $200 stock, an increase in expiring open 
interest in P.M.-settled SPX options equal to $10 billion to effect a 
price movement less than half a standard deviation, and an increase in 
total P.M.-settled SPX settlement quantity equal to $7 billion to 
achieve a price reversal greater two standard deviations.
    The study employed the same metrics to determine whether there is 
greater price volatility for S&P 500 futures, the S&P 500, and the 
component securities of the S&P 500 related to SPXPM option settlements 
during an environment of high market volatility (i.e., on days in which 
the VIX Index was in the top 10% of closing index values) and did not 
identify indicators of any significant economic impact on these markets 
near the close as a result of the P.M.-settled SPX options 
settlement.\27\ In addition to this, the DERA staff study, applying the 
same metrics and analysis as for P.M.-settled SPX options to A.M.-
settled SPX options, did not identify any evidence of a statistically 
significant relationship between settlement quantity or expiring open 
interest of A.M.-settled options and volatility near the open.
---------------------------------------------------------------------------

    \27\ The Exchange also notes that the study did not identify any 
evidence that less liquid S&P 500 constituent securities experienced 
any greater impact from the settlement of P.M.-settled SPX options.
---------------------------------------------------------------------------

    Upon review of the results of the DERA staff study, the Exchange 
agrees that each of the above-described marginal price movements in S&P 
500 futures, the S&P 500, and the S&P 500 component securities affected 
by increases in P.M.-settled SPX options settlement quantity and 
expiring open interest appear to be de minimis pricing changes from 
those that occur over regular trading hours (outside of the last 15 
minutes of the trading day). Further, the Exchange has not observed any 
significant economic impact or other adverse effects on the market from 
similar reviews of its pilot reports and data submitted after 2018.\28\ 
In its review of a sample of the pilot data from 2019 through 2021, the 
Exchange similarly measured volatility over the final fifteen minutes 
of each trading day by taking the standard deviation of rolling one-
minute returns of the S&P 500 level (excluding the first and last 
fifteen minutes of trading) and comparing such with the standard 
deviation of one-minute returns \29\ of the S&P 500 level, over the 
last 15 minutes of a trading day. The Exchange identified an average 
standard deviation ratio of 1.42 for the S&P 500 on non-expiration days 
and an average standard deviation ratio of 1.54 for the S&P 500 on 
expiration days (a ratio between expiration days and non-expiration 
days of 1.09). The Exchange also notes that, using the same 
methodology, it observed that, from 2015 through 2019,\30\ the average 
standard deviation ratio for the S&P 500 on non-expiration days was 
1.11 and the average standard deviation ratio for the S&P 500 on 
expiration days was 1.22 (a ratio between expiration days and non-
expiration days of 1.10). While the average standard deviation ratio on 
both expiration and non-expiration days was higher in 2019 through 2021 
due to overall market volatility, the ratios between the standard 
deviation ratios on expiration days and non-expirations days remained 
nearly identical between the 2015 through 2019 timeframe and the 2019 
through 2021. This shows that, in cases where overall market volatility 
may increase, the normalized impact on expiration days to non-
expiration days generally remains consistent.
---------------------------------------------------------------------------

    \28\ Total SPX open interest volumes were examined for 
expiration dates over a roughly two-year period between October 2019 
and November 2021.
    \29\ Calculated at every tick for the prior minute.
    \30\ November 2015 through November 2021.
---------------------------------------------------------------------------

    In addition to this, the Exchange notes that the S&P 500 is 
rebalanced quarterly. The changes resulting from each rebalancing 
coincide with the third-Friday of the quarterly rebalancing month 
(i.e., March, June, September, October and December) \31\ and generally 
drive an increase in trading activity from investors that seek to track 
the S&P 500. As such, the Exchange measured volatility on quarterly 
rebalancing dates and found that the average standard deviation ratio 
was 1.62, which suggests more closing volatility on quarterly rebalance 
dates compared to non-quarterly expiration dates (for which the average 
standard deviation ratio was 1.22), thus indicating that the impact 
rebalancing may have on the S&P 500 is greater than any impact that 
P.M.-settled SPX options may have on the S&P 500.

---------------------------------------------------------------------------

    The Exchange additionally focused its study of the post-2018 sample 
pilot data on reviewing for potential correlation between excess market 
volatility and price reversals and the hedging activity of liquidity 
providers. As explained in the DERA staff study, potential impact of 
P.M.-settled SPX options on the correlated equity markets is thought to 
stem from the hedging activity of liquidity providers in such 
options.\32\ To determine any such potential correlation, the Exchange 
studied the expected action of liquidity providers that are the primary 
source of the hedging on settlement days. These liquidity providers 
generally delta-hedge their S&P 500 index exposure via S&P 500 futures 
and on settlement day unwind their futures positions that correspond 
with the delta of their in-the-money (ITM) expiring P.M.-settled SPX 
options. Assuming such behavior, the Exchange estimated the Market-On-
Close (``MOC'') \33\ volume for the shares of the S&P 500 component 
securities (i.e., ``MOC share volume'') that could ultimately result 
from the unwinding of the liquidity providers' futures positions by 
equating the notional value of the futures positions that correspond to 
expiring ITM open interest to the number S&P 500 component security 
contracts (based on the weight of each S&P 500 component security). 
That is, the Exchange calculated (an estimate) of the amount of MOC 
volume in the S&P 500 component markets attributable hedging activity 
as a result of expiring ITM P.M.-settled SPX options (i.e., ``hedging 
MOC''). The Exchange then:

[[Page 26357]]

(1) compared the hedging MOC share volume to all MOC share volume on 
expiration days and non-expiration trading days; and (2) compared the 
notional value of the hedging futures positions (i.e., that correspond 
to expiring ITM P.M.-settled SPX options open interest) to the notional 
value of expiring ITM P.M.-settled SPX options open interest, the 
notional value of all expiring P.M.-settled SPX options open interest 
and the notional value of all P.M.-settled SPX options open interest.
---------------------------------------------------------------------------

    \32\ See DERA Staff PM Pilot Memo, at 10-12.
    \33\ MOC orders allow a market participant to trade at the 
closing price. Market participants generally utilize MOC orders to 
ensure they exit positions at the end of the trading day.
---------------------------------------------------------------------------

    The Exchange observed that, on average, there were approximately 
25% more MOC shares executed on expiration days (332 expiration days) 
than non-expiration days (209 non-expiration days). While, at first 
glance, the volume of MOC shares executed on expiration days seems much 
greater than the volume executed on non-expiration days, the Exchange 
notes that much of this difference is attributable to just eight 
expiration days--the quarterly index rebalancing dates captured within 
the scope of the post-2018 sample pilot data. The average MOC share 
volume on the eight quarterly rebalancing dates was approximately 4.8 
times the average MOC share volume on the non-quarterly rebalancing 
expiration dates; again, indicating that the impact rebalancing may 
have on the S&P 500 Index is greater than any impact that P.M.-settled 
SPX options may have on the S&P 500 Index. That is, the Exchange 
observed that the majority of closing volume on quarterly rebalance 
dates is driven by rebalancing of shares in in the S&P 500, and not by 
P.M.-settled SPX options expiration-related hedging activity. 
Notwithstanding the MOC share volume on quarterly rebalancing dates, 
the volume of MOC shares executed on expiration days (324 expiration 
days) was only approximately 13% more than that on non-expiration days, 
substantially less than the increase in volume over non-expiration days 
wherein the eight index rebalancing dates are included in expiration 
day volume. In addition to this, the Exchange observed that the hedging 
MOC share volume (i.e., the expected MOC share volume resulting from 
hedging activity in connection with expiring ITM P.M.-settled SPX 
options) was, on average, less than the MOC share volume on non-
expiration days, and was only approximately 20% of the total MOC share 
volume on expiration days, indicating that other sources of MOC share 
volume generally exceed the volume resulting from hedging activity of 
expiring ITM P.M.-settled SPX options and would more likely be a source 
of any potential market volatility.
    The Exchange also observed that, across all third-Friday 
expirations, the notional value of the hedging futures positions was 
approximately 25% of the notional value of expiring ITM P.M.-settled 
SPX options, approximately 3.8% of the notional value of all expiring 
P.M.-settled SPX options, and approximately only 0.5% of the notional 
value of all P.M.-settled SPX options. As such, the estimated hedging 
activity from liquidity providers on expiration days is a fraction of 
the expiring open interest in P.M.-settled SPX options, which, the 
Exchange notes, is only 14% of the total open interest in P.M.-settled 
SPX options; thus, indicating negligible capacity for hedging activity 
to increase volatility in the underlying markets.
    While unrelated to the initial concerns of P.M.-settlement as 
described above, at the request of the Commission, the Exchange 
recently completed an analysis intended to evaluate whether the 
introduction of P.M.-settled options impacted the quality of the A.M.-
settled option market. Specifically, the Exchange compared values of 
key market quality indicators (specifically, the bid-ask spread \34\ 
and effective spread \35\) in SPXW options both before and after the 
introduction of Tuesday expirations and Thursday expirations for SPXW 
options on April 18 and May 11, 2022, respectively.\36\ Options on the 
Standard & Poor's Depositary Receipts S&P 500 ETF (``SPY'') were used 
as a control group to account for any market factors that might 
influence key market quality indicators. The Exchange used data from 
January 3, 2022 through March 4, 2022 (the two-month period prior to 
the introduction of SPXW options with Tuesday expirations) and data 
from May 11, 2022 to July 10, 2022 (the two-month period following the 
introduction of SPXW options with Thursday expirations).\37\
---------------------------------------------------------------------------

    \34\ The Exchange calculated for each of SPXW options (with 
Monday, Wednesday, and Friday expirations) and SPY Weekly options 
(with Monday, Wednesday, and Friday expirations) the daily time-
weighted bid-ask spread on the Exchange during its regular trading 
hours session, adjusted for the difference in size between SPXW 
options and SPY options (SPXW options are approximately ten times 
the value of SPY options).
    \35\ The Exchange calculated the volume-weighted average daily 
effective spread for simple trades for each of SPXW options (with 
Monday, Wednesday, and Friday expirations) and SPY Weekly options 
(with Monday, Wednesday, and Friday expirations) as twice the amount 
of the absolute value of the difference between an order execution 
price and the midpoint of the national best bid and offer at the 
time of execution, adjusted for the difference in size between SPXW 
options and SPY options.
    \36\ For purposes of comparison, the Exchange paired SPXW 
options and SPY options with the same moneyness and same days to 
expiration.
    \37\ The Exchange observed comparable market volatility levels 
during the pre-intervention and post-intervention time ranges.
---------------------------------------------------------------------------

    Given the time that as passed since the introduction of FLEX P.M.-
settled options, the Exchange is unable to analyze whether the 
introduction of those options significantly impacted the market quality 
of FLEX P.M.-settled options. Additionally, the Exchange is unable to 
analyze whether the introduction of the FLEX P.M.-settled options 
significantly impacted the market quality of A.M.-settled FLEX options, 
as there is no book for FLEX options, as FLEX options are listed only 
if and when market participants create them for trading. However, the 
Exchange believes analyzing whether the introduction of new SPXW P.M.-
settled expirations (i.e., SPXW options with Tuesday and Thursday 
expirations) impacted the market quality of then-existing SPXW P.M.-
settled expirations (i.e., SPXW options with Monday, Wednesday, and 
Friday expirations) provides a reasonable substitute to evaluate 
whether the introduction of P.M.-settled index options impacted the 
market quality of the underlying cash markets when the pilot began. The 
full analysis is included in Exhibit 3 of this rule filing.
    As a result of this analysis, the Exchange believes the 
introduction of SPX options with Tuesday and Thursday options had no 
significant impact on the market quality of SPXW options with Monday, 
Wednesday, and Friday expirations. With respect to the majority of 
series analyzed, the Exchange observed no statistically significant 
difference in the bid-ask spread or the effective spread of the series 
in the period prior to introduction of the Tuesday and Thursday 
expirations and the period following the introduction of the Tuesday 
and Thursday expirations. While statistically insignificant, the 
Exchange notes that in many series, particularly as they were closer to 
expiration, the Exchange observed that the values of these spreads 
decreased during the period following the introduction of the Tuesday 
and Thursday expirations.\38\
---------------------------------------------------------------------------

    \38\ In any series in which the Exchange observed an increase in 
the market quality indicators, the Exchange notes any such increase 
was also statistically insignificant.
---------------------------------------------------------------------------

    To further note, given the significant changes in the closing 
procedures of the primary markets in recent decades, including 
considerable advances in trading systems and technology, the Exchange 
believes that the risks of any potential impact of P.M.-, cash-settled

[[Page 26358]]

FLEX options on the underlying cash markets are also de minimis.
    The Exchange proposes to make the FLEX PM Third Friday Program 
permanent as P.M.-settled index products have become an integral part 
of the Exchange's product offerings, providing investors with greater 
trading opportunities and flexibility. As indicated by the significant 
growth in the size of the market for P.M.-settled options, such options 
have been, and continue to be, well-received and widely used by market 
participants. Therefore, the Exchange wishes to be able to continue to 
provide investors with the ability to trade FLEX PM options on a 
permanent basis. The Exchange believes that the permanent continuation 
of the FLEX PM Third Friday Pilot Program will serve to maintain the 
status quo by continuing to offer a product to which investors have 
become accustomed and have incorporated into their business models and 
day-to-day trading methodologies for nearly ten years. As such, the 
Exchange also believes that ceasing to offer FLEX PM options may result 
in significant market disruption and investor confusion. The Exchange 
has not identified any significant impact on market quality nor any 
unique or prohibitive regulatory concerns as a result of the FLEX PM 
Third Friday Pilot Program, and, as such, the Exchange believes that 
the continuation of the FLEX PM Third Friday Pilot Program as a pilot, 
including the use of time and resources to compile and analyze 
quarterly and annual pilot reports and pilot data, is no longer 
necessary and that making the FLEX PM Third Friday Pilot Program 
permanent will allow the Exchange to otherwise allocate time and 
resources to other industry initiatives.
2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the Securities Exchange Act of 1934 (the ``Act'') and the rules and 
regulations thereunder applicable to the Exchange and, in particular, 
the requirements of section 6(b) of the Act.\39\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
section 6(b)(5) \40\ requirements that the rules of an exchange be 
designed to prevent fraudulent and manipulative acts and practices, to 
promote just and equitable principles of trade, to foster cooperation 
and coordination with persons engaged in regulating, clearing, 
settling, processing information with respect to, and facilitating 
transactions in securities, to remove impediments to and perfect the 
mechanism of a free and open market and a national market system, and, 
in general, to protect investors and the public interest.
---------------------------------------------------------------------------

    \39\ 15 U.S.C. 78f(b).
    \40\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    In particular, the Exchange believes that the making the FLEX PM 
Third Friday Pilot Program permanent will allow the Exchange to be able 
to continue to offer FLEX PM options on a continuous and permanent 
basis. These products have been, and continue to be, well-received and 
widely used by market participants, providing investors with greater 
trading opportunities and flexibility. The Exchange believes that the 
permanent continuation of the FLEX PM Third Friday Pilot Program will 
remove impediments to and perfect the mechanism of a free and open 
market and a national market system, and, in general, protect investors 
and the public interest by continuing to offer a product to which 
investors have become accustomed and have incorporated into their 
business models and day-to-day trading strategies for approximately 13 
years. The Exchange believes ceasing to offer the FLEX PM Third Friday 
Pilot Program may result in significant market disruption and investor 
confusion, as P.M.-settled index products, particularly SPX options, 
have become an integral part of the Exchange's product offerings, 
providing investors with greater trading opportunities and flexibility.
    The Exchange further believes that making the FLEX PM Third Friday 
Pilot Program permanent will remove impediments to and perfect the 
mechanism of a free and open market and a national market system and 
protect investors, while maintaining a fair and orderly market, as the 
Exchange believes that previous concerns (arising in the 1980s) 
regarding options expirations potentially contributing to excess 
volatility and reversals around the close have been adequately 
diminished. As described in detail above, the Exchange has observed no 
significant adverse market impact or identified any meaningful 
regulatory concerns during the approximately 13-year operation of the 
FLEX PM Third Friday Program as a pilot nor during the 15 years since 
P.M.-settled index options (SPX) were reintroduced to the 
marketplace.\41\ Notably, the Exchange did not identify any significant 
economic impact (including on pricing or volatility or in connection 
with reversals) on related futures, the underlying indexes, or the 
underlying component securities of the underlying indexes surrounding 
the close as a result of the quantity of P.M.-settled FLEX options that 
settle at the close or the amount of expiring open interest in P.M.-
settled FLEX options, nor any demonstrated capacity for options hedging 
activity to impact volatility in the underlying markets. While the DERA 
staff study and corresponding Exchange study described above 
specifically evaluated SPX options, P.M.-settled FLEX options overlay 
broad-based indexes (including the S&P 500), the Exchange believes it 
is appropriate to extrapolate the data to apply the FLEX PM options. 
This is particularly true given that the reports submitted by the 
Exchange during the pilot period have similarly demonstrated no 
significant economic impact on the respective underlying indexes or 
other products.
---------------------------------------------------------------------------

    \41\ See supra notes 18-31.
---------------------------------------------------------------------------

    The Exchange also believes the introduction of FLEX PM options had 
no significant impact on the market quality of corresponding A.M.-
settled options or other options. The Exchange believes this as a 
result of its analysis conducted after the introduction of SPXW options 
with Tuesday and Thursday expirations, which demonstrated no 
statistically significant impact on the bid-ask or effective spreads of 
SPXW options with Monday, Wednesday, and Friday expirations after 
trading in the SPXW options with Tuesday and Thursday expirations 
began. FLEX options are nearly identical to non-FLEX options and 
overlay the same indexes. Therefore, the Exchange believes analyzing 
the impact of new SPXW options on then-existing SPXW options permit the 
Exchange to extrapolate from this data that it is unlikely the 
introduction of P.M.-settled FLEX options significantly impacted the 
market quality of A.M.-settled options when the pilot began.
    Additionally, the significant changes in the closing procedures of 
the primary markets in recent decades, including considerable advances 
in trading systems and technology, has significantly minimized risks of 
any potential impact of P.M.-, cash-settled FLEX options on the 
underlying cash markets. As such, the Exchange believes that a 
permanent FLEX PM Third Friday Pilot Program does not raise any unique 
or prohibitive regulatory concerns and that such trading has not, and 
will not, adversely impact fair and orderly markets on Expiration 
Fridays for the underlying indexes or their component securities. 
Further, as the Exchange has not identified any significant impact on 
market quality or any unique or prohibitive regulatory concerns as a 
result of offering FLEX PM options, the

[[Page 26359]]

Exchange believes that the continuation of the FLEX PM Third Friday 
Pilot Program as a pilot, including the gathering, submission and 
review of the pilot reports and data, is no longer necessary and that 
making the FLEX PM Third Friday Pilot Program permanent will allow the 
Exchange to otherwise allocate time and resources to other industry 
initiatives.

B. Self-Regulatory Organization's Statement on Burden on Competition

    Cboe Options does not believe that the proposed rule change will 
impose any burden on competition that is not necessary or appropriate 
in furtherance of the purposes of the Act. The Exchange does not 
believe that making the FLEX PM Third Friday Pilot Program permanent 
will impose any unnecessary or inappropriate burden on intramarket 
competition because FLEX PM options will continue to be available to 
all market participants who wish to participate in the FLEX PM options 
market. The Exchange believes that the growth that the P.M.-settled 
options market, including FLEX PM options, has experienced since their 
reintroduction through pilot programs indicates strong, continued 
investor interest and demand, warranting a permanent FLEX PM Third 
Friday Pilot Program. The Exchange believes that, for the period that 
P.M.-settled FLEX options have been in operation as pilot programs, 
they have provided investors with a desirable product with which to 
trade and wishes to permanently offer this product to investors. 
Furthermore, during the pilot period, the Exchange has not observed any 
significant adverse market effects nor identified any regulatory 
concerns as a result of the FLEX PM Third Friday Pilot Program, and, as 
such, the continuation of the FLEX PM Third Friday Pilot Program as a 
pilot, including the gathering, submission and review of the pilot 
reports and data, is no longer necessary--a permanent FLEX PM Third 
Friday Pilot Program will allow the Exchange to otherwise allocate time 
and resources to other industry initiatives.
    The Exchange further does not believe that making the FLEX PM Third 
Friday Pilot Program permanent will impose any burden on intermarket 
competition that is not necessary or appropriate in furtherance of the 
purposes of the Act because it applies to a class of options listed 
only for trading on Cboe Options. The Exchange notes that other 
exchanges are free to and do offer competing products. To the extent 
that the permanent offering and continued trading of FLEX PM options 
may make Cboe Options a more attractive marketplace to market 
participants at other exchanges, such market participants may elect to 
become Cboe Options market participants.
