          - [Release No. 34-98450; File No. SR-ISE-2023-08]

## I. Introduction

                    On February 23, 2023, Nasdaq ISE LLC (“ISE” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”), pursuant to section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) [1]                                          and Rule 19b-4 thereunder,[2]                                          a proposed rule change to make permanent the pilot program to permit the listing and trading of options based on                     1/5                     the value of the Nasdaq-100 Index (“Nasdaq-100”) and the Exchange's nonstandard expirations pilot program (collectively, the “Programs”). The proposed rule change was published for comment in the                     **Federal Register**                     on March 2, 2023.[3]                                          On April 7, 2023, pursuant to section 19(b)(2) of the Act,[4]                                          the Commission designated a longer period within which to approve the proposed rule change, disapprove the proposed rule change, or institute proceedings to determine whether to disapprove the proposed rule change.[5]                                          On May 11, 2023, the Exchange filed Amendment No. 1 to the proposed rule change (“Amendment No. 1”).[6]                                          On May 31, 2023, the Commission instituted proceedings to determine whether to approve or disapprove the proposed rule change and published Amendment No. 1 for notice and comment.[7]                                          On August 28, 2023, the Commission designated a longer period for Commission action on proceedings to determine whether to approve or disapprove the proposed rule change, as modified by Amendment No. 1.[8]                                          The Commission did not receive any comment letters and is approving the proposed rule change, as modified by Amendment No. 1.                

## II. Background

                    When cash-settled [9]                                          index options were first introduced in the 1980s, they generally utilized closing-price settlement procedures (                    *i.e.,*                     p.m. settlement).[10]                                          The Commission became concerned with the impact of p.m.-settled, cash-settled index options on the underlying cash equities markets, and in particular, added market volatility and sharp price movements near the close on expiration days.[11]                                          These concerns were heightened during the “triple-witching” hour on the third Friday of March, June, September, and December when index options, index futures, and options on index futures expired concurrently.[12]                                          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.[13] 

                    In light of the concerns with p.m. settlement and to help ameliorate the price effects associated with expirations                           ( print page 66112)                        of p.m.-settled, cash-settled index products, in 1987, the Commodity Futures Trading Commission approved a proposed rule change by the Chicago Mercantile Exchange (“CME”) to provide for a.m. settlement [14]                                          for index futures, including futures on the S&P 500 Index.[15]                                          The Commission subsequently approved a proposed rule change by Cboe Options Exchange (“Cboe Options”) to list and trade a.m.-settled options on the S&P 500 Index.[16]                                          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.[17]                                          However, in 1993, the Commission approved a proposed rule change allowing Cboe Options to list p.m.-settled options on certain broad-based indexes, including the S&P 500, expiring at the end of each calendar quarter (since approved as permanent).[18]                                          Starting in 2006, the Commission approved a number of proposals, on a pilot basis, permitting Cboe Options to introduce other index 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,[19]                                          as well as p.m.-settled S&P 500 Index options and Mini-S&P 500 Index options expiring on the third Friday of the month.[20] 

                    Subsequently, other exchanges, including ISE, sought to permit the listing and trading of p.m.-settled options on certain broad-based indices. In February 2018, the Commission approved ISE's nonstandard expirations pilot program on a pilot basis (“Nonstandard Pilot”).[21]                                          In March 2018, the Commission approved ISE's pilot to permit the listing and trading of options based on the Nasdaq 100 Reduced Value Index (“NQX” or “NQX options”) on a pilot basis (“NQX Pilot”).[22]                                          In the course of approving both Programs, the Commission reiterated its concern about the potential impact on the market at expiration for the underlying component stocks for a p.m.-settled, cash-settled index option.[23]                                          However, the Commission also recognized the potential impact was unclear.[24]                                          The Commission approved the Programs on a pilot basis to allow the Exchange and the Commission to monitor for and assess any potential for adverse market effects.[25]                                          In order to facilitate this assessment, the Exchange committed to provide the Commission with data and analysis for each pilot [26]                                          and to make such data publicly available.[27]                                          In addition to the Exchange's data and analysis, Cornerstone Research also conducted an analysis at the direction of Staff from the Commission's Division of Economic and Risk Analysis. The analysis utilizes the level of expiring p.m.-settled index options open interest and the measures of volatility and price reversals for the corresponding index futures, the underlying cash index, and index component securities in the minutes leading up to and immediately following the market close to study the effects of pilot programs allowing p.m.-settled index options. The Pilot Memo is discussed in more detail below.                

## III. Description of the Proposal, as Modified by Amendment No. 1

                    The Exchange proposes to make permanent the Nonstandard Pilot and the NQX pilot. The Nonstandard Pilot permits the Exchange to open p.m.-settled options on broad-based indexes that expire (1) on the last day of the trading month (“EOM expirations”) and (2) on any Monday, Wednesday, or Friday (other than the third Friday-of-the-month or days that coincide with an EOM expiration) and, with respect to options on the Nasdaq-100 (“NDX” or “NDX options”), any Tuesday or Thursday (other than days that coincide with the third Friday-of-the-month or an EOM expiration). The NQX Pilot permits the listing of NQX options, which are European-style and cash-settled, and have a contract multiplier of 100. The contract specifications for NQX options mirror those of the NDX options contract listed on the Exchange, except that NQX options are based on                     1/5                     of the value of the Nasdaq-100, and are p.m.-settled pursuant to Options 4A, section 12(a)(6) of the ISE Rules.                

                    The Nonstandard Pilot was extended on multiple occasions, including recently, and is set to expire on November 6, 2023.[28]                                          Similarly, the NQX Pilot was extended on multiple occasions and is set to expire on November 6, 2023.[29] 

                    The Exchange states it has provided pilot data to the Commission with respect to the Programs, pursuant to the Nonstandard Approval Order and the NQX Approval order.[30]                                          The Exchange                           ( print page 66113)                        also states it provides ongoing monthly data in addition to the data provided in the Notice.[31]                                          Now, the Exchange proposes to make the Programs permanent.                

## IV. Discussion and Commission Findings

                    After careful review, the Commission finds that the proposed rule change, as modified by Amendment No. 1, is consistent with the Act and the rules and regulations thereunder applicable to a national securities exchange.[32]                                          In particular, the Commission finds that the proposed rule change, as modified by Amendment No. 1, is consistent with section 6(b)(5) of the Act,[33]                                          which requires, among other things, that the Exchange's rules be designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, 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 its proposal to make the Programs permanent, the Exchange addressed market capacity around the market close and provided an empirical assessment of the impact of its p.m.-settled index options on options market quality. Each of these elements is discussed in greater detail below. As stated above, no comments were received on the proposed rule change.                

### Market Impact Considerations

                    The Exchange's analysis presents data that the introduction of p.m.-settlement is correlated with an increase in options trading tied to the Nasdaq-100.[34]                                          The data shows an increase in trading volume and notional open interest for NDX and NQX options during the sample period.[35] 

                    In addition to reviewing the data and analysis provided by the Exchange, the Commission reviewed the analysis in the Pilot Memo, which evaluates whether higher levels of expiring open interest in p.m.-settled index options results in increased volatility and price reversals around the close. The Pilot Memo shows that the market share for p.m.-settled options, in particular options on S&P 500 Index, has grown substantially since 2007.[36]                                          The Pilot Memo examines whether and to what extent expiring open interest in p.m.-settled index options is empirically related with the tendency of the corresponding index futures, the underlying index, or index components to experience increased transitory volatility and price reversals around the time of market close on expiration dates. The Pilot Memo concludes that, although expiring p.m.-settled index option open interest may have a statistically significant relationship with volatility and price reversals of the underlying index, index futures, and index component securities around the market close, the magnitude of the effect is economically very small.[37]                                          For example, the largest settlement event that occurred during the time period studied in the Pilot Memo (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).[38] 

                    In order to analyze the effect of a very large increase in settlement volume for Nasdaq-100 p.m.-settled options contracts, the Exchange uses the estimated regression coefficients in the Pilot Memo to estimate the change in the volatility of index futures prices when settlement volume increased from the 25th percentile to the 75th percentile.[39]                                          For both the S&P 500 Index and the Nasdaq-100, the Exchange estimates the relative impact would be small for both indexes.[40] 

                    The Exchange also provides additional analysis on market capacity around the market close.[41]                                          Specifically, the Exchange presents data that the closing auction volume on the equity market have become much larger than the opening auction, which may indicate that there is sufficient liquidity in closing auctions to absorb liquidity demand associated with p.m.-settlement of NDX and NQX options.[42]                                          In addition, the Exchange states that the liquidity available at or around the close would be able to mitigate any excess volatility created by the options settlement at the market close.[43] 

                    Further, the Exchange represents that it has sufficient systems capacity to handle p.m.-settled options on broad-based indexes with nonstandard expirations dates and has not encountered any issues or adverse market effects as a result of listing them.[44] 

### Market Quality Considerations

                    The Exchange also completed an analysis intended to evaluate whether the Programs impacted the quality of the NDX options market. Specifically, the Exchange presents findings on three market characteristics: trading volume, open interest, and spreads. The Exchange concludes that there is no evidence that NDX and NQX options contracts, which are p.m.-settled, would result in reduced trading activity or degradation in market quality of the a.m.-settled index options.[45]                                          The Exchange notes within its analysis that it seems unlikely that the introduction of NQX option contracts had a significant impact on the market quality of the full-sized NDX option contracts.[46] 

                    Further, the Exchange observed a consistent decrease in relative quoted spread from 2017 to 2022 for NDX options.[47]                                          When the Exchange compared the spread trend of NDX monthly contracts to that of QQQ monthly contracts, the Exchange states that the results suggest that there is gradual decrease in both the NDX monthly contracts spread and the QQQ contracts spread during the sample period.[48]                                          The Exchange uses duration weighted relative quoted spread as a measure of the cost of trading and examines whether the introduction of p.m.-settled index options results in any deterioration of spreads for am-settled NDX options.[49]                                          The Exchange finds a consistent decrease in the relative quoted spread is prevalent from 2017 to 2022 and no obvious change in the trend following the introduction of p.m.-settled index options.[50]                                          The analysis also considered whether the move from a.m. settlement to p.m. settlement for Friday weekly expirations                           ( print page 66114)                        (other than third-Friday-of-the-month) led to changes in spreads for those contracts.[51]                                          The sample timeframe was from July 2017 through August 2018.[52]                                          The relative quoted spread decreased during first part of 2018 and increase in May and June 2018; however, it remained comparable to the 2017 average.[53]                                          Overall, the Exchange observes no evidence of deterioration of spreads associated with the introduction of p.m.-settled NDX options.[54] 

The Commission believes that the evidence contained in the Exchange's filing, the Exchange's pilot data and reports, and the Pilot Memo analysis demonstrate that the Programs have benefitted investors and other market participants by providing more flexible trading and hedging opportunities while also having no disruptive impact on the market. The market for p.m.-settled options has grown in size over the course of the Programs, and analysis of the pilot data did not identify any significant economic impact on the underlying component securities surrounding the close as a result of expiring p.m.-settled options nor did it indicate a deterioration in market quality (as measured by relative quoted spreads) for an existing product when a new p.m.-settled expiration was introduced. Further, significant changes in closing procedures in the decades since index options moved to a.m. settlement may also serve to mitigate the potential impact of p.m.-settled index options on the underlying cash markets.

                    Accordingly, the Commission finds that the proposed rule change, as modified by Amendment No. 1, is consistent with section 6(b)(5) of the Act [55]                                          and the rules and regulations thereunder applicable to a national securities exchange.                

## V. Conclusion

*It is therefore ordered,*                     pursuant to section 19(b)(2) of the Act,[56]                                          that the proposed rule change (SR-ISE-2023-08), as modified by Amendment No. 1, be, and hereby is, approved.                

                        For the Commission, by the Division of Trading and Markets, pursuant to delegated authority.[57]
