Self-Regulatory Organizations; Investors Exchange LLC; Notice of Filing and Immediate Effectiveness of Proposed Rule Change To Amend IEX Rule 11.280 To Extend the Pilot Period for the Market-Wide Circuit Breaker to the Close of Business on October 18, 2021

Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”) and Rule 19b-4 thereunder, notice is hereby given that, on October 5, 2020, the Investors Exchange LLC (“IEX” or the “Exchange”) filed with the Securities and Exchange Commission (the “Commission”) the proposed rule change as described in Items I and II below, which Items have been prepared by the self-regulatory organization. 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

Pursuant to the provisions of Section 19(b)(1) under the Act, and Rule 19b-4 thereunder, IEX is filing with the Commission a proposed rule change to amend IEX Rule 11.280 to extend the pilot period for the market-wide circuit breaker to the close of business on October 18, 2021. IEX has designated this rule change as “non-controversial” under Section 19(b)(3)(A) of the Act and provided the Commission with the notice required by Rule 19b-4(f)(6) thereunder.

The text of the proposed rule change is available at the Exchange's website at www.iextrading.com,, at the principal office of the Exchange, and at the Commission's Public Reference Room.

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

In its filing with the Commission, the self-regulatory organization 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 statement may be examined at the places specified in Item IV below. The self-regulatory organization 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 the Statutory Basis for, the Proposed Rule Change

1. Purpose

Paragraphs (a) through (d) and (f) of Rule 11.280 describe the methodology for determining when to halt trading in all stocks due to extraordinary market volatility (i.e., market-wide circuit breakers). The market-wide circuit breaker (“MWCB”) mechanism under Rule 11.280 was approved by the Commission to operate on a pilot basis, the term of which was to coincide with the pilot period for the Plan to Address Extraordinary Market Volatility Pursuant to Rule 608 of Regulation NMS (the “LULD Plan”), including any extensions to the pilot period for the LULD Plan. In April 2019, the Commission approved an amendment to the LULD Plan for it to operate on a permanent, rather than pilot, basis. In light of the proposal to make the LULD Plan permanent, the Exchange amended Rule 11.280 to untie the pilot's effectiveness from that of the LULD Plan and to extend the pilot's effectiveness to the close of business on October 18, 2019. The Exchange subsequently amended Rule 11.280 to extend the pilot's effectiveness for an additional year to the close of business on October 18, 2020.

The purpose of this proposed rule change is to amend Rule 11.280(a) to extend the pilot period for the MWCB, set forth in paragraphs (a) through (d) and (f), to the close of business on October 18, 2021. This filing does not propose any substantive or additional changes to Rule 11.280.

MWCBs under Rule 11.280 provide an important, automatic mechanism that is invoked to promote stability and investor confidence during periods of significant stress when securities markets experience extreme broad-based declines. All SROs have rules relating to MWCBs, which are designed to slow the effects of extreme price movement through coordinated trading halts across securities markets when severe price declines reach levels that may exhaust market liquidity. MWCBs provide for trading halts in all equities and options markets during a severe market decline as measured by a single-day decline in the S&P 500 Index.

Pursuant to Rule 11.280(a) through (d) and (f), a market-wide trading halt will be triggered if the S&P 500 Index declines in price by specified percentages from the prior day's closing price of that index. Currently, the triggers are set at three circuit breaker thresholds: A 7% market decline (Level 1), a 13% market decline (Level 2), and a 20% market decline (Level 3). A market decline that triggers a Level 1 or Level 2 circuit breaker after 9:30 a.m. ET and before 3:25 p.m. ET would halt market-wide trading for 15 minutes, while a similar market decline at or after 3:25 p.m. ET would not halt market-wide trading. A market decline that triggers a Level 3 circuit breaker, at any time during the trading day, would halt market-wide trading for the remainder of the trading day.

Since the MWCB pilot was last extended in October 2019, the MWCB mechanism has proven itself to be an effective tool for protecting markets through turbulent times. In the Spring of 2020, at the outset of the worldwide COVID-19 pandemic, U.S. equities markets experienced four MWCB Level 1 halts, on March 9, 12, 16, and 18, 2020. In each instance, the markets halted as intended upon a 7% drop in the S&P 500 Index, and resumed as intended 15 minutes later.

In response to these events, the previously-convened MWCB Taskforce (“Taskforce”) reviewed the March 2020 halts and considered whether any immediate changes to the MWCB mechanism should be made. The Taskforce, consisting of representatives from equities exchanges, futures exchanges, FINRA, broker-dealers, and other market participants, had been assembled in early 2020 to consider more generally potential changes to the MWCB mechanism. The Taskforce held ten meetings in the Spring and Summer of 2020 that were attended by Commission staff to consider, among other things: (1) Whether to retain the S&P 500 Index as the standard for measuring market declines; (2) whether halts that occur shortly after the 9:30 a.m. market open cause more harm than good; and (3) what additional testing of the MWCB mechanism should be done.

After considering data and anecdotal reports of market participants' experiences during the March 2020 MWCB events, the Taskforce did not recommend immediate changes be made to the use of the S&P 500 Index as the reference price against which market declines are measured, or to the current MWCB mechanism which permits halts even shortly after the 9:30 a.m. market open. The Taskforce recommended creating a process for a backup reference price in the event that the S&P 500 Index becomes unavailable, and enhancing functional MWCB testing. The Taskforce also asked the Chicago Mercantile Exchange, Inc. to consider modifying its rules to enter into a limit-down state in the futures pre-market after a 7% decline instead of 5%.

On September 17, 2020, the Director of the Commission's Division of Trading and Markets requested that the equities exchanges and FINRA prepare a more complete study of the design and operation of the MWCB mechanism and the LULD Plan during the period of volatility in the Spring of 2020. Based on the results of that study, the Exchange expects to work with the Commission, FINRA, the other exchanges, and market participants to determine if any additional changes to the MWCB mechanism should be made, including consideration of rules and procedures for the periodic testing of the MWCB mechanism with industry participants.

In addition to the work of the Taskforce, the equities exchanges also moved forward in 2019 and 2020 with a plan to normalize their Day 2 opening procedures after a Level 3 MWCB halt, such that all exchanges would reopen on Day 2 with a standard opening auction. The Exchange filed a rule change to that effect in March 2020, and successfully tested the implementation of those changes on September 12, 2020.

2. Statutory Basis

The Exchange believes that its proposal is consistent with the requirements of Sections 6(b) and 6(b)(5) of the Act, in particular, 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. The MWCB mechanism under Rule 11.280 is an important, automatic mechanism that is invoked to promote stability and investor confidence during periods of significant stress when securities markets experience extreme broad-based declines. Extending the MWCB pilot for an additional year would ensure the continued, uninterrupted operation of a consistent mechanism to halt trading across the U.S. equity markets while the Exchange, with the other SROs, studies the design and operation of the MWCB mechanism and the LULD Plan during the period of volatility in the Spring of 2020. Based on the results of that study, the Exchange expects to work with the Commission, FINRA, the other exchanges, and market participants to determine if any additional changes to the MWCB mechanism should be made, including consideration of rules and procedures for the periodic testing of the MWCB mechanism with industry participants.

The Exchange also believes that the proposed rule change promotes just and equitable principles of trade in that it promotes transparency and uniformity across markets concerning when and how to halt trading in all stocks as a result of extraordinary market volatility. Based on the foregoing, the Exchange believes the benefits to market participants from the MWCB under Rule 11.280(a) through (d) and (f) should continue on a pilot basis because the MWCB will promote fair and orderly markets, and protect investors and the public interest.

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

IEX does not believe that the proposed rule change implicates any competitive issues because the proposal would ensure the continued, uninterrupted operation of a consistent mechanism to halt trading across the U.S. markets while the Exchange, in conjunction with the other SROs, studies the design and operation of the MWCB mechanism and the LULD Plan during the period of volatility in the Spring of 2020.

Further, IEX understands that the other SROs will file proposals to extend their rules regarding the MWCB pilot. Thus, the proposed rule change will help to ensure consistency across market centers without implicating any competitive issues.

C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others

Written comments were neither solicited nor received.

III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action

The Exchange has designated this rule filing as non-controversial under Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) thereunder. Because the proposed rule change does not: (i) Significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) become operative for 30 days from the date on which it was filed, or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) thereunder.

A proposed rule change filed under Rule 19b-4(f)(6) normally does not become operative for 30 days after the date of filing. However, pursuant to Rule 19b-4(f)(6)(iii), the Commission may designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has asked the Commission to waive the 30-day operative delay so that the proposal may become operative upon filing. Extending the pilot for an additional year will allow the uninterrupted operation of the existing pilot, while FINRA, and the other exchanges conduct a study of the MWCB mechanism in consultation with market participants and determine if any additional changes to the MWCB mechanism should be made, including consideration of rules and procedures for the periodic testing of the MWCB mechanism with industry participants. Therefore, the Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest. The Commission hereby designates the proposed rule change to be operative upon filing.

At any time within 60 days of the filing of the proposed rule change, the Commission summarily may temporarily suspend such rule change if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission shall institute proceedings under Section 19(b)(2)(B) ²³ of the Act to determine whether the proposed rule change should be approved or disapproved.
