Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) ^[1] and Rule 19b-4 thereunder,^[2] notice is hereby given that on June 11, 2020, Cboe Exchange, Inc. (the “Exchange” or “Cboe Options”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I, II, and III below, which Items have been prepared by the Exchange. The Commission is publishing this notice to solicit comments on the proposed rule change from interested persons.

I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change

Cboe Exchange, Inc. (the “Exchange” or “Cboe Options”) proposes to amend its automated price improvement auction rules in connection with Agency Order size requirements. The text of the proposed rule change is provided in Exhibit 5.

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 amend Rule 5.37(a)(3) and Rule 5.38(a)(8) to allow the Exchange to determine maximum size requirements for Agency Orders in SPX submitted though the Automated Price Improvement Mechanism (“AIM” or “AIM Auction”) and the Complex Automated Price Improvement Mechanism (“C-AIM” or “C-AIM Auction”).

Currently, Rules 5.37(a)(3) and 5.38(a)(3), which govern the size requirements for AIM and C-AIM Agency and Initiating Orders, provide that there is no minimum size for orders submitted into AIM and C-AIM Auctions, respectively, and that the Initiating Order must be for the same size as the Agency Order. As such, an Agency Order of any size ^[3] may currently be submitted in an AIM or C-AIM Auction.

The Exchange now proposes to amend Rule 5.37(a)(3) to provide that the Exchange may determine a maximum size requirement for Agency Orders in SPX, and by amending Rule 5.38(a)(3) to provide that the Exchange may determine a maximum size requirement for the smallest leg of an Agency Order in SPX.^[4] The Exchange believes that the proposed flexibility to allow the Exchange to determine to limit the size of SPX Agency Orders submitted in an AIM or C-AIM Auction will allow the Exchange to appropriately address the specific trading characteristics, market model, and investor basis of SPX. The Exchange notes that the maximum size requirement for Agency Orders in SPX would apply to all Agency Orders in the entire SPX class (including SPX Weeklys (“SPXW”)).

In particular, SPX has a different and more complicated market model, ( printed page 36919) involves taking on greater risk, has a significantly higher notional value ( e.g., they are ten times the notional size of SPY options), tends to trade in much larger size, and tends to execute increasingly more complex strategies ( e.g., SPX Combo orders) than in other options classes. The Exchange understands these factors may limit retail customer participation in SPX to simpler strategies and smaller-sized orders. These factors also have contributed to the Exchange's historical determination to not activate AIM in SPX when the floor is open so to encourage liquidity on the trading floor to accommodate these large and complex trades. Therefore, the Exchange believes the application of an Agency Order size ceiling may provide more price improvement opportunities in SPX geared towards retail customers. The Exchange believes this may incentivize increased retail customer auction participation in SPX and provide retail customers with execution and price improvement opportunities in SPX while incentivizing continued liquidity on the trading floor for larger and more complex orders.

The Exchange has observed that increased smaller size order flow tends to attract Market-Maker responses, as such orders are generally easier to hedge than larger orders, which may encourage Market-Makers to compete to provide price improvement in an electronic competitive auction process. This, in turn, may contribute to a deeper, more liquid auction process with additional price improvement opportunities for market participants, and particularly retail customers. The Exchange notes, too, that the Exchange's trading floor may be better suited for crosses in SPX with more complex orders, complicated strategies and larger size. Such orders are more generally executed on the trading floor, where Trading Permit Holders (“TPHs”) may negotiate and fine-tune the terms of a trade. In addition to this, the trading crowd in open outcry may provide markets that are more tailored to the complexity and size of orders typically submitted in SPX. Greater execution and price improvement opportunities for SPX orders may result from the markets given by the trading crowd that better define the nuanced complexity and size of such orders than if the same orders were submitted via AIM or C-AIM—which, instead, may provide greater price improvement opportunities for simpler and smaller orders. Permitting the Exchange to determine a maximum size for SPX orders submitted to AIM and C-AIM will enable the Exchange to activate AIM and C-AIM in SPX to provide additional price improvement opportunities for smaller orders and maintain liquidity on the trading floor for larger complex orders, thus creating a liquid hybrid environment for orders in this class.

In a sample of SPX orders submitted into simple AIM during a week of trading in April 2020,^[5] the Exchange observed that orders containing quantities from one to ten contracts submitted through AIM received an average price improvement of approximately $0.34 over their limit prices, orders containing quantities from 11 to 50 contracts received an average price improvement of approximately $0.22, and orders for 51 to 100 contracts received an average price improvement of $0.08; whereas, orders containing quantities of between 100 and 250 contracts received an average of $0.08 and orders containing quantities of between 251 and 500 received an average of $0.15. That is approximately 325% larger average price improvement that orders for one to ten contracts received than orders for 100 to 250 contracts and approximately 127% larger average price improvement than orders for 251 to 500 contracts. The Exchange also observed this trend generally in the sample of SPX orders submitted to C-AIM, as well, where greater price improvement generally occurred for smaller sized orders as compared to larger sized orders. For C-AIM, the Exchange observed that orders for one to ten contracts received an average price improvement of $0.14, for 11 to 50 contracts received an average of $1.69, and for 51 to 100 contracts received an average of $2.36; whereas orders for 100 to 250 contracts received an average price improvement of $1.15 and orders for 251 to 500 contracts received an average of $0.24. As this data demonstrates, price improvement on smaller orders in SPX, a class which generally exhibits more complicated trading characteristics and complex market factors, is generally more beneficial than price improvement on larger orders submitted through AIM and C-AIM.^[6] As a result, if the Exchange is able to implement a maximum size requirement for SPX as proposed, it may determine to activate AIM when the trading floor is open. The Exchange believes this could incentive the submission of smaller size SPX orders to the Exchange. As a result, the Exchange believes the proposed rule change will provide retail customers with additional price improvement opportunities for retail customers overall when the trading floor is open while preserving liquidity available in the market, particularly on the trading floor, for larger and more complicated orders.

Finally, pursuant to current Rule 5.37.02 and Rule 5.38.02, it is deemed conduct inconsistent with just and equitable principles of trade and a violation of Exchange Rule 8.1 to engage in a pattern of conduct where the Initiating Member breaks up an Agency Order into separate orders for the purpose of gaining a higher allocation percentage than the Initiating TPH would have otherwise received in accordance with the allocation procedures contained in the AIM and C-AIM Rules, respectively. In light of the proposed rule change, the Exchange also proposes to amend Rules 5.37.02 and 5.38.02 to make it clear that Initiating TPHs also may not break up an Agency Order into separate orders for the purpose of circumventing a maximum quantity requirement as determined by the Exchange pursuant to subparagraph(s) (a)(3). The Exchange notes that its surveillance program will monitor for such violations in the same manner in which it currently monitors for allocation-related break up violations.

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.^[7] Specifically, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) ^[8] 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. ( printed page 36920) Additionally, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) ^[9] requirement that the rules of an exchange not be designed to permit unfair discrimination between customers, issuers, brokers, or dealers.

In particular, the Exchange believes the proposed rule change to allow the Exchange to determine a maximum size for AIM and C-AIM Agency Orders in SPX will provide the Exchange with the flexibility to activate AIM and C-AIM Auctions for SPX in a manner the Exchange believes will appropriately address the different trading characteristics, market model, investor basis and conditions presented in SPX as compared to different option classes. The Exchange has considered these factors in its determination to not activate AIM and C-AIM in SPX when operating in a normal hybrid trading environment. With the proposed rule change, the Exchange would consider activating AIM and C-AIM in SPX when the trading floor is open to provide additional execution and price improvement opportunities to retail customers. The Exchange believes this may encourage an increase smaller-sized SPX orders and meaningful and competitive responses to the auctions, as applicable, which ultimately benefits investors and retail customers in particular.

The Exchange acknowledges that price improvement auctions have provided the market with benefits, such as providing an efficient manner of access to liquidity for customers. However, the options industry overall has observed that quoted liquidity on the book has decreased, quotes have widened, and options market makers have reduced their participation in the market, which has impacted market quality.^[10] Thus, the Exchange believes that the flexibility to impose a maximum order size for these auctions would permit the Exchange to provide retail customers in SPX with access to these auctions while continuing to create incentives for SPX Market-Makers to continue to provide liquidity in the in the trading crowd for larger and more complex orders. As such, the Exchange believes the proposed rule change may encourage a general increase in retail order flow and execution opportunities in AIM and C-AIM Auctions in SPX, thus enhancing the quality of the auctions, while maintaining market quality and liquidity for larger and more complicated orders, which removes impediments to and perfects the mechanism of a free and open market and a national market system, and benefits the entire market and all investors.

In addition to this, the Exchange does not believe that the proposed rule change would significantly impact TPHs that submit larger and more complicated orders in SPX because the trading floor is generally better suited and more appropriate for such orders, where TPHs tend to execute much larger and more complex orders given the flexibility to negotiate and fine-tune the terms of an order.^[11] As discussed above, the Exchange believes not permitting these larger orders to execute in AIM and C-AIM auctions will create incentives for Market-Makers to continue to provide on the trading floor to execute against those orders. Additionally, given that the Exchange does not generally activate AIM and C-AIM in SPX, the proposed rule change will have no impact on larger orders, which TPHs are unable to submit into AIM and C-AIM Auctions when the trading floor is open. In addition, the Exchange believes that the proposed rule change to amend Rules 5.37.02 and 5.38.02 would protect investors by prohibiting TPHs to break up Agency Orders to circumvent maximum size requirements.

The Exchange does not believe that the purpose of the proposed rule change to accommodate retail customers is new or unique, as the Exchange and other options exchanges currently have rules, such as certain reduced fees and market structure benefits, in place that provide preferential treatment to or are geared toward benefitting retail customers particularly. Moreover, the Exchange believes that the proposed rule change is consistent with longstanding precedent, thus indicating that it is consistent with the Act, to provide reasonable incentives to retail investors that rely on the public markets for their investment needs. Indeed, the Commission has long stressed the need to ensure that the markets are structured in a way that meets the needs of ordinary investors.^[12] The Exchange believes that the proposed rule change would assist the Exchange in achieving the Commission's stated goal of improving the retail investor experience in the public markets while protecting overall market quality.

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

The Exchange 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 the proposed rule change will impose any burden on intramarket competition that is not necessary or appropriate in furtherance of the purposes of the Act, because it will apply to all Agency Orders in SPX where the Exchange imposes a maximum size submitted into the AIM and C-AIM auctions by all market participants. The Exchange believes having the ability to designate a maximum size for SPX orders only is appropriate given the trading characteristics, market model, investor base, and large notional value of SPX options compared to other options. The Exchange believes all market participants in SPX may benefit from any additional liquidity and price improvement in the AIM and C-AIM Auctions that may result from the proposed rule change. Moreover, the Exchange believes that determination of a maximum quantity in SPX would not significantly affect TPHs that submit larger and more complicated orders as open outcry auctions are generally better suited to facilitating liquidity for larger order size and/or more complex order strategies. The Exchange notes it generally does not activate AIM and C-AIM in SPX options, so the proposed rule change would have no impact on larger-sized SPX orders that currently are not permitted to be submitted into AIM and C-AIM auctions when the Exchange is operating in a normal hybrid trading environment. The Exchange believes not permitting larger orders into these auctions will encourage Market-Makers to continue to provide liquidity in the trading crowd while providing retail customers with price improvement opportunities, which may increase competition for these orders. As stated above, the Exchange believes the proposed rule change is consistent with the Commission's goal and industry practice to provide reasonable incentives to retail investors that rely on ( printed page 36921) the public markets for their investment needs. The Exchange also notes the proposed rule change has no impact on the allocation or priority of orders and responses at the conclusion of AIM and C-AIM auctions. Additionally, any Agency Order for less than 50 contracts must continue to have an auction price that improves the then-current NBBO.

The Exchange does not believe the proposed rule change will impose any burden on intermarket competition that is not necessary or appropriate in furtherance of the purposes of the Act, as the proposed rule change relates to an Exchange-specific auction mechanism in a class of options only listed for trading on the Exchange. The Exchange also notes that other options exchanges offer similar price improvement auctions ^[13] that are available to market participants, and other options exchanges may, in their discretion, adopt similar flexibility in connection with their auctions.
