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 the Fee Schedule to implement a SPIKES Options Market Maker Incentive Program (the “Incentive Program”) for the period beginning October 1, 2021, and ending December 31, 2021. The Incentive Program is designed to improve liquidity, volume, and quote width spreads in SPIKES options. Technical details regarding the Incentive Program were published in a Regulatory Circular on September 30, 2021. The Exchange originally filed this proposal on September 30, 2021, (SR-MIAX-2021-45). On October 12, 2021, the Exchange withdrew SR-MIAX-2021-45 and refiled this proposal.

Background

On October 12, 2018, the Exchange received approval from the Commission to list and trade options on the SPIKES® Index, which measures expected 30-day volatility of the SPDR® S&P 500 ETF Trust (commonly known and referred to by its ticker symbol, “SPY”). The Exchange adopted its initial SPIKES transaction fees on February 15, 2019. Options on the SPIKES Index began trading on the Exchange on February 19, 2019.

SPIKES Options Market Maker Incentive Program

The Exchange proposes to implement a SPIKES Options Market Maker Incentive Program for SPIKES options to incentivize Market Makers to improve liquidity, available volume, and the quote spread width of SPIKES options. To be eligible to participate in the Incentive Program, a Market Maker must meet certain minimum requirements related to quote spread width in certain in-the-money (ITM) and out-of-the-money (OTM) options as determined by the Exchange and communicated to Members via Regulatory Circular. Market Makers must also satisfy a minimum time in the market in the front 2 expiry months of 70%, and have an average quote size of 25 contracts.

The Exchange proposes to establish two separate incentive compensation pools that will be used to compensate Market Makers that satisfy the criteria pursuant to the proposed Incentive Program.

Incentive 1 Pool

The first pool (Incentive 1) will be a total amount of $40,000 per month, which will be allocated to Market Makers that meet the minimum requirements of the Incentive Program. Market Makers will be required to meet minimum spread width requirements in a select number of ITM and OTM SPIKES option contracts as determined by the Exchange and communicated to Members via Regulatory Circular. A complete description of how the Exchange calculates the minimum spread width requirements in ITM and OTM SPIKES options can be found in the published Regulatory Circular, additionally an example is provided below. Market Makers will also be required to maintain the minimum spread width, described above, for at least 70% of the time in the front two (2) SPIKES options contract expiry months and maintain an average quote size of at least 25 SPIKES options contracts. The amount available to each individual Market Maker will be capped at $10,000 per month for satisfying the minimum requirements of the Incentive Program. In the event that more than four Market Makers meet the requirements of the Incentive Program, each qualifying Market Maker will be entitled to receive a pro-rated share of the $40,000 monthly compensation pool dependent upon the number of qualifying Market Makers in that particular month. For example, if five Market Makers qualify for compensation under Incentive 1 of the Incentive Program, each Market Maker would receive a rebate of $8,000 for that particular month.

Incentive 2 Pool

The second pool (Incentive 2 Pool) will be capped at a total amount of $100,000 per month which will be used during the Incentive Program to further incentivize Market Makers who meet or exceed the requirements of Incentive 1 (“qualifying Market Makers”) to provide tighter quote width spreads. The Exchange will rank each qualifying Market Maker's quote width spread relative to each other qualifying Market Maker's quote width spread. Market Makers with tighter spreads in certain strikes, as determined by the Exchange and communicated to Members via Regulatory Circular, will be eligible to receive a pro-rated share of the compensation pool as calculated by the Exchange and communicated to Members via Regulatory Circular, not to exceed $25,000 per Member per month. Qualifying Market Makers will be ranked relative to each other based on the quality of their spread width ( i.e., tighter spreads are ranked higher than wider spreads) and the Market Maker with the best quality spread width will receive the highest rebate, while other eligible qualifying Market Makers will receive a rebate relative to their quality spread width.

Incentive Pool 2 Example

Each qualifying Market Maker's ITM/OTM market width for eligible Incentive Program options will be calculated, weighted, and ranked. ITM market width will be given a 25% weighting and OTM market width will be given a 75% weighting. Eligible ITM options require a maximum quote width spread of 150 basis points (“bps”) and each eligible OTM option requires a maximum quote width of 100 bps (as calculated below).

The formula employed by the Exchange to calculate the bps for an individual strike is: {(Ask Quote−Bid Quote)/Futures price} * 10,000, where the futures price is in the same expiry being measured. For example, a SPIKE 19 Put expiring on 10/20/2021 has a bid quote of $0.25 and an ask quote of $.45 and the October SPIKE Future is trading at 20.30. Using the aforementioned formula the Exchange can calculate the Member's bps on that strike as: {($0.45−$0.25)/20.30} * 10,000; or ($0.20/20.30) * 10,000; or .009852 * 10,000 = 98.52217 bps. To establish the market quality baseline bps the Exchange combines target bps in ITM and OTM options (150 bps * 25% = 37.5 bps and 100 bps * 75% = 75 bps; 37.5 bps + 75 bps = 112.50 bps).

To determine the pool amount the Exchange will contribute $5,000 for each basis point improvement from the Exchange established baseline of 112.50 bps. The Exchange will calculate a Member's Improvement Value (“MIV”) by subtracting the Member's monthly average bps from the Exchange established baseline of 112.50 bps. If for the month “Market Maker A” has an average score of 109 and “Market Maker B” has an average score of 107 the Exchange will calculate the amount of Incentive Pool 2 based on the average total improvement of the qualifying Market Makers from the baseline and for every bps of improvement the Exchange will contribute $5,000 to Incentive Pool 2. In this example, the average of “Market Maker A” (109) and “Market Maker B” (107) is 108. The Exchange would therefore contribute $22,500 to Incentive Pool 2 (112.5−108 = 4.5 * $5,000).

The Exchange will calculate a pro-rata distribution for each Market Maker based upon their improvement value, which is the number of bps improvement from the Exchange established baseline of 112.5. “Market Maker A” has an MIV of 3.5 (112.5−109) and “Market Maker B” has an MIV of 5.5 bps (112.5 = 107). To determine each Market Makers' pro-rata share of the Incentive 2 Pool the Exchange sums the MIVs of each Market Maker (3.5 + 5.5) = 9 and divides each Market Maker's MIV by that total to establish their weighted percentage: 38.89% and 61.11% for “Market Maker A” and “Market Maker B,” respectively. “Market Maker A” would then be entitled to 38.89% of the $22,500 Incentive 2 Pool or $8,750. Whereas “Market Maker B” would be entitled to 61.11% of the $22,500 Incentive 2 Pool or $13,750.

The total amount in Incentive Pool 2 is capped at $100,000 per month and the total amount allocated to any one Member is capped at $25,000 per month.

The details of the Incentive Program are contained in a Regulatory Circular distributed to all Members.

2. Statutory Basis

The Exchange believes that its proposal to amend its Fee Schedule is consistent with Section 6(b) of the Act in general, and furthers the objectives of Section 6(b)(4) of the Act in particular, in that it is an equitable allocation of reasonable fees and other charges among its members and issuers and other persons using its facilities. The Exchange also believes the proposal furthers the objectives of Section 6(b)(5) of the Act in that it is designed 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 and is not designed to permit unfair discrimination between customers, issuers, brokers and dealers.

The Exchange believes that it is reasonable, equitable, and not unfairly discriminatory to adopt an Incentive Program for Market Makers in SPIKES options. The Incentive Program is reasonably designed because it will incent Market Makers to provide quotes and increased liquidity in select SPIKES options contracts. The proposed Incentive Program is reasonable, equitably allocated and not unfairly discriminatory because all Market Makers in SPIKES options may qualify for Incentive 1 and Incentive 2, dependent upon each Market Maker's quoting in SPIKES options in a particular month. Additionally, if a SPIKES Market Maker does not satisfy the requirements of Incentive Pool 1 or 2, then it simply will not receive the rebate offered by the Incentive Program for that month.

The Exchange believes that it is reasonable, equitable and not unfairly discriminatory to offer this financial incentive to SPIKES Market Makers because it benefits all market participants trading in SPIKES. SPIKES Options is a Proprietary Product on the Exchange and this Incentive Program encourages SPIKES Market Makers to satisfy a heightened quoting standard, average quote size, and time in market. An increase in quoting activity and tighter quotes may yield a corresponding increase in order flow from other market participants, which benefits all investors by deepening the Exchange's liquidity pool, potentially providing greater execution incentives and opportunities, while promoting market transparency and improving investor protection.

The Exchange believes that the Incentive Program is equitable and not unfairly discriminatory because it will promote an increase in SPIKES options liquidity, which may facilitate tighter spreads and an increase in trading opportunities to the benefit of all market participants. The Exchange believes it is reasonable to operate the Incentive Program for a limited period of time to strengthen market quality for all market participants. The resulting increased volume and liquidity will benefit those Members who are eligible to participate in the Incentive Program and will also benefit those Members who are not eligible to participate in the Incentive Program by providing more trading opportunities and tighter spreads.

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 not necessary or appropriate in furtherance of the purposes of the Act.

Intra-Market Competition

The Exchange believes that the proposal to adopt an Incentive Program does not impose any burden on intra-market competition that is not necessary or appropriate in furtherance of the purposes of the Act.

The Exchange believes that the proposal would increase intra-market competition by incentivizing Market Makers to quote SPIKES options, which will enhance the quality of quoting and increase the volume of contracts available to trade in SPIKES options. To the extent that this purpose is achieved, all the Exchange's market participants should benefit from the improved market liquidity for SPIKES options. Enhanced market quality and increased transaction volume in SPIKES options that results from the anticipated increase in Market Maker activity on the Exchange will benefit all market participants and improve competition on the Exchange.

Inter-Market Competition

The Exchange believes the proposed rule change does not impose any burden on inter-market competition that is not necessary or appropriate in furtherance of the purposes of the Act. The proposed changes in connection with the Incentive Program are limited to SPIKES options which are a proprietary product of the Exchange and as such are listed and traded exclusively on the Exchange.

Additionally, as noted above, the Incentive Program is designed to improve volume and liquidity in SPIKES options. Greater volume and liquidity benefits all market participants by providing more trading opportunities, tighter spreads, and added market transparency and price discovery. The Exchange notes that it operates in a highly competitive market in which market participants can readily direct order flow to competing venues if they deem fee levels at a particular venue to be excessive or incentives to be insufficient. More specifically, the Exchange is only one of 16 options venues to which market participants may direct their order flow. Based on publicly available information, no single options exchange has more than 13% of the market share. Thus, in such a low-concentrated and highly competitive market, no single options exchange possess significant pricing power in the execution of option order flow.

Accordingly, the Exchange does not believe its proposal to adopt an Incentive Program imposes any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act.
