Self-Regulatory Organizations; Investors Exchange LLC; Notice of Filing and Immediate Effectiveness of a Proposed Rule Change To Amend IEX Rule 11.280 Concerning the Resumption of Trading Following a Level 3 Market-Wide Circuit Breaker Halt

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 March 18, 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 concerning the resumption of trading following a Level 3 market-wide circuit breaker halt. 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 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 Statutory Basis for, the Proposed Rule Change

1. Purpose

The Exchange proposes to amend IEX Rule 11.280(b) concerning the resumption of trading following a Level 3 market-wide circuit breaker halt. The Exchange is proposing this rule change in conjunction with other national securities exchanges and the Financial Industry Regulatory Authority (“FINRA”).

IEX Rule 11.280 provides a 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 mechanism (“MWCB”) under IEX 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. The Commission recently 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 IEX 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 then filed to extend the pilot for an additional year to the close of business on October 18, 2020.

The market-wide circuit breaker under IEX Rule 11.280 provides an important, automatic mechanism that is invoked to promote stability and investor confidence during a period of significant stress when securities markets experience extreme broad-based declines. All U.S. equity exchanges and FINRA adopted uniform rules on a pilot basis relating to market-wide circuit breakers in 2012 (“MWCB Rules”), 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. Market-wide circuit breakers 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 IEX Rule 11.280, 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: 7% (Level 1), 13% (Level 2), and 20% (Level 3). A market decline that triggers a Level 1 or Level 2 halt 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 halt at any time during the trading day would halt market-wide trading until the primary listing market opens the next trading day.

Today, in the event that a Level 3 market decline occurs, the Exchange would halt trading for the remainder of the trading day and would not resume until the primary listing market opens the next trading day. Thus, if the primary listing market is the New York Stock Exchange, Inc. (“NYSE”), IEX would not resume trading in NYSE-listed securities until NYSE opens at 9:30 a.m. ET on the next trading day. But if the primary listing market is the Nasdaq Stock Market LLC (“Nasdaq”), IEX would resume trading in Nasdaq-listed securities at 8:00 a.m. ET on the next trading day, when IEX commences its Pre-Market Session. Effectively, Nasdaq would open its listed securities for trading following a Level 3 halt the same as a regular trading day under the current MWCB Level 3 re-opening procedures. For non-Nasdaq listed securities, however, IEX would resume trading once the primary listing market has re-opened the security for trading, which time may currently vary depending on the primary listing market.

Upon feedback from industry participants, the Exchange has been working with other national securities exchanges and FINRA to establish a standardized approach for resuming trading in all NMS Stocks following a Level 3 halt. The proposed approach would allow for the opening of all securities the next trading day after a Level 3 halt as a regular trading day and is designed to ensure that Level 3 MWCB events are handled in a more consistent manner that is transparent for market participants.

As proposed, a Level 3 halt would end at the end of the trading day on which it is declared. This proposed change would allow for next-day trading to resume in all NMS Stocks no differently from any other trading day. In other words, an exchange could resume trading in any security when it first begins trading under its rules and would not need to wait for the primary listing market to re-open trading in a security before it could start trading such security. Accordingly, under the proposal, the Exchange could begin trading all securities at the beginning of the Exchange's Pre-Market Session, just as it currently does for Nasdaq-listed securities.

To effect this change, the Exchange proposes to delete the language in IEX Rule 11.280(b)(2) requiring the Exchange to wait until the primary listing exchange opens the next trading day following a Level 3 market decline, and specify that the Exchange will halt trading for the remainder of the same trading day. The proposed rule change would therefore allow each exchange to resume trading in all securities the next trading day following a Level 3 halt at whatever time such exchange normally begins trading under its rules, which for IEX would be at the beginning of the Pre-Market Session at 8:00 a.m. ET under its current rules. The Exchange also expects that the primary listing exchanges will facilitate this change by sending resume messages to the applicable securities information processor (“SIP”) to lift the Level 3 trading halt message in all securities. The resumption messages will be disseminated after the SIP has started on the next trading day and before the start of the earliest pre-market trading session of all exchanges. If a security is separately subject to a regulatory halt that has not ended, the primary listing exchange would replace the Level 3 halt message with the applicable regulatory halt message.

Having a consistent approach for all securities will make the opening process the day after a Level 3 halt more uniform and reduce complexity, which the Exchange believes is important after a significant market event. Based on industry feedback, the Exchange believes that opening in the normal course in all equity securities as opposed to, for instance, having a normal opening for Nasdaq-listed securities only or waiting for the primary listing exchange to conduct a halt auction prior to resuming trading, will be more beneficial to the marketplace. By allowing trading to resume after a Level 3 halt in all securities no differently from any normal trading day under the respective rules of each exchange, the proposed rule change would provide greater certainty to the marketplace by ensuring a familiar experience for all market participants that trade NMS Stocks and balances out potential concerns around volatility. While the Exchange recognizes that the impact of this proposal is to permit all securities to be traded in the Pre-Market Session, which does not have certain price protections for volatility such as LULD Bands or MWCB protections, the Exchange nonetheless believes that this outcome is outweighed by the benefits provided by opening in the Pre-Market Session in a manner that is more familiar to the marketplace. Moreover, allowing the resumption of trading to occur on the Exchange at the beginning of the Pre-Market Session in all NMS Stocks will allow for price formation to occur earlier in the trading day, which in turn allows market participants to react to news that has developed. As such, trading at the beginning of regular hours may be more orderly.

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 market-wide circuit breaker mechanism under IEX Rule 11.280 is an important, automatic mechanism that is invoked to promote stability and investor confidence during a period of significant stress when securities markets experience extreme broad-based declines. The Exchange 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, and how the markets will resume trading following a Level 3 market decline. As described above, the Exchange, together with other national securities exchanges and FINRA, is seeking to adopt a standardized approach related to resuming trading in NMS Stocks after a Level 3 MWCB halt. In this regard, the Exchange believes that the proposal to resume trading in all securities following a Level 3 halt in the same manner that securities would open trading on a regular trading day (i.e., the beginning of the Pre-Market Session at 8 a.m. ET on IEX) will benefit investors, the national market system, Exchange Members, and the Exchange market by promoting a fair and orderly market and reducing confusion during a significant cross-market event. By allowing trading to resume after a Level 3 halt in all securities no differently from any normal trading day under the respective rules of each exchange, the proposed rule change would provide greater certainty to the marketplace by ensuring a familiar experience for all market participants that trade NMS Stocks.

Based on the foregoing, the Exchange believes the benefits to market participants from the MWCB under IEX Rule 11.280 with the proposed standardized process for resuming trading in all securities following a Level 3 halt 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 will impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act because the proposed Level 3 rule change described above would standardize the opening process for all securities on the Exchange, which would make the opening process the day after a Level 3 halt more uniform and reduce complexity. Further the Exchange understands that FINRA and the other national securities exchanges will file similar proposals to adopt the proposed Level 3 rule change.

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 filed the proposed rule change pursuant to Section 19(b)(3)(A)(iii) 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 prior to 30 days from the date on which it was filed, or such shorter time as the Commission may designate, if consistent with the protection of investors and the public interest, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6)(iii) thereunder.

A proposed rule change filed under Rule 19b-4(f)(6) normally does not become operative prior to 30 days after the date of the 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 immediately upon filing. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest. The Commission notes that it approved a substantively similarly proposed rule change submitted by Nasdaq. Waiver of the operative delay will ensure consistency across the market centers and the timely implementation of the proposed rule change. Accordingly, the Commission waives the 30-day operative delay and designates the proposed rule change operative upon filing.

At any time within 60 days of the filing of such 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) of the Act to determine whether the proposed rule change should be approved or disapproved.
