Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) 
and Rule 19b-4 thereunder,
notice is hereby given that, on January 25, 2013, National Stock Exchange, Inc. (the “Exchange” or “NSX”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I and II 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
The Exchange proposes to delay the operative date of a rule change to Exchange Rule 11.20A, which provides for methodology for determining when to halt trading in all stocks due to extraordinary market volatility, from the date of February 4, 2013, until April 8, 2013.
The text of the proposed rule change is available on the Exchange's Web site at http://www.nsx.com, at the principal office of the Exchange, and at the Commission's Public Reference Room [sic].
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 parts of such statements.
A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change
The Exchange proposes to amend Exchange Rule 11.20A, which provides the methodology for determining when to halt trading in all stocks due to extraordinary market volatility, to delay the operative date of the pilot by which such Rule operates from the current scheduled date of February 4, 2013, until April 8, 2013, to coincide with the initial date of operations of the Regulation NMS Plan to Address Extraordinary Market Volatility (“LULD Plan”).
As proposed, the pilot period will begin and end at the same time the pilot period for the LULD Plan. The current Exchange Rule 11.20A would remain in effect until April 8, 2013. If the pilot is not either extended or approved permanently at the end of the pilot period, the current version of Exchange Rule 11.20A would be in effect.
Current Exchange Rule 11.20A
The rule provides for Level 1, 2, and 3 declines and specified trading halts following such declines. The values of Levels 1, 2 and 3 [sic] are calculated at the beginning of each calendar quarter, using 10%, 20% and 30%, respectively, of the average closing value of the (“DJIA”) for the month prior to the beginning of the quarter. Each percentage calculation is rounded to the nearest fifty points to create the Levels' trigger points. The New York Stock Exchange, Inc. (“NYSE”) disseminates the new trigger levels quarterly to the media and via an Information Memo and [sic] is available on the NYSE's Web site.
The values then remain in effect until the next quarterly calculation, notwithstanding whether the DJIA has moved and a Level 1, 2, or 3 decline is no longer equal to an actual 10%, 20%, or 30% decline in the most recent closing value of the DJIA.
Once an Exchange Rule 11.20A circuit breaker is in effect, trading in all stocks halt [sic] for the time periods specified below:
Level 1 Halt
Anytime before 2:00 p.m.—one hour;
At or after 2:00 p.m. but before 2:30 p.m.—30 minutes;
At or after 2:30 p.m.—trading shall continue, unless there is a Level 2 Halt.
Level 2 Halt
Anytime before 1:00 p.m.—two hours;
At or after 1:00 p.m. but before 2:00 p.m.—one hour;
At or after 2:00 p.m.—trading shall halt and not resume for the rest of the day.
Level 3 Halt
At any time—trading shall halt and not resume for the rest of the day.
Unless stocks are halted for the remainder of the trading day, price indications are disseminated during a Rule 11.20A trading halt for stocks that comprise the DJIA.
Amended Exchange Rule 11.20A
The Exchange amended Exchange Rule 11.20A to revise the current methodology for determining when to halt trading in all stocks due to extraordinary market volatility (“market-wide circuit breakers”).
The Exchange, other equities, options, and futures markets, and FINRA amended the market-wide circuit breakers to take into consideration the recommendations of the Joint CFTC-SEC Advisory Committee on Emerging Regulatory Issues, and to provide for more meaningful measures in today's markets of when to halt trading in all stocks. Accordingly, the Exchange amended Rule 11.20A as follows: (i) Replaced the DJIA with the S&P 500; (ii) replaced the quarterly calendar recalculation of Exchange Rule 11.20A triggers with daily recalculations; (iii) replaced the 10%, 20%, and 30% market decline percentages with 7%, 13%, and 20% market decline percentages; (iv) modified the length of the trading halts associated with each market decline level; and (v) modified the times when a trading halt may be triggered. The Exchange believes that these amendments update the rule to reflect today's high-speed, highly electronic trading market while still meeting the original purpose of Exchange Rule 11.20A: To ensure that market participants have an opportunity to Start Printed Page 8639become aware of and respond to significant price movements.
The Exchange adopted the proposed changes to the market-wide circuit breakers on a pilot basis for a period that corresponds to the pilot period for the LULD Plan so that the impact of the two proposals can be reviewed together.
In addition, in order for the markets and the single plan processors responsible for the consolidation of information pursuant to Rule 603(b) of Regulation NMS under the Securities Exchange Act of 1934 to make the necessary technological changes to implement both the changes to the market-wide circuit breakers and the proposed LULD Plan, the Exchange established that the implementation date for the proposed rule changes should be the same date that the LULD Plan is implemented. The Exchange anticipates that the initial date of LULD Plan operations will be changed to April 8, 2013. For the same reasons as stated above, the Exchange proposes to delay the operative date of the market-wide circuit breaker pilot to April 8, 2013 in order for the implementation date for the market-wide circuit breaker pilot to remain the same date as for the LULD Plan.
2. Statutory Basis
The Exchange believes that its proposal is consistent with Section 6(b) of the Securities Exchange Act of 1934 (the “Act”),
in general, and furthers the objectives of Section 6(b)(5) of the Act,
in particular, in that it is 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.
Specifically, this rule proposal supports the objectives of perfecting the mechanism of a free and open market and the national market system because it promotes uniformity across markets concerning when and how to halt trading in all stocks as a result of extraordinary market volatility. Additionally, delaying the operative date of the market-wide circuit breakers pilot until the initial date of operations of the LULD Plan would allow the pilot to begin and end at the same time of the LULD Plan so that the Exchange and the Commission could further assess the impact of the two pilots on the marketplace or whether other initiatives should be adopted in lieu of the pilots, which contributes to the protection of investors and the public interest.
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 proposed changes are being made to delay the operation of the market-wide circuit breakers pilot until April 8, 2013 to allow the pilot period to begin and end at the same time as the LULD Plan, which contributes to the protection of investors and the public interest. Other competing equity exchanges are subject to the same methodology for determining when to halt trading in all stocks due to extraordinary market volatility and the same requirements specified in the LULD Plan. Thus, the proposed changes will not impose any burden on competition while providing that the market-wide circuit breakers pilot period corresponds to the pilot period for the LULD Plan so that the impact of the two proposals can be reviewed together.
C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others
Written comments on the proposed rule change were neither solicited nor received.
III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action
Because the foregoing proposed rule change does not significantly affect the protection of investors or the public interest, does not impose any significant burden on competition, and, by its terms, does not 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.
The Exchange has requested that the Commission waive the 30-day operative delay. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest. Doing so will delay the operative date of the market-wide circuit breakers pilot until the initial date of operations of the LULD Plan, thereby allowing the pilot to run simultaneously with the LULD Plan, providing an opportunity to properly assess the impact of the two pilots on the marketplace and evaluate the pilots' effectiveness. Therefore, the Commission designates the proposal 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) 
of the Act to determine whether the proposed rule change should be approved or disapproved.
