Self-Regulatory Organizations; NASDAQ OMX PHLX LLC; Notice of Filing and Immediate Effectiveness of Proposed Rule Change Related to Non-Display of Primary Pegged Orders With an Offset Amount

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 March 23, 2012, NASDAQ OMX PHLX LLC (“Phlx” or “Exchange”) 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 Exchange has designated the proposed rule change as constituting a rule change under Rule 19b-4(f)(6) under the Act, which renders the proposal effective upon filing with the Commission. 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 provide amend Exchange Rule 3301(f)(4) to provide for non-display of Primary Pegged Orders with an offset amount. The text of the proposed rule change is available at: http://www.nasdaqtrader.com/micro.aspx?id=PHLXRulefilings , at the Exchange's principal office, 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 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 those 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

1. Purpose

Phlx proposes to amend Rule 3301(f)(4) to provide that Primary Pegged Orders with an offset amount will be non-displayed, a change that will improve system and inter-market price stability. Pegged Orders are orders that, once entered, adjust in price automatically, in response to changes in the inside bids or offers of NASDAQ OMX PSX (“PSX”) or the national market system, depending upon the type of Pegged Order. A Primary Pegged Order specifies that its price will equal the inside quote on the same side of the market; a Market Pegged Order will equal the inside quote on the opposite side of the market. A Midpoint Peg Order will equal the midpoint of the national best bid and offer (“NBBO”), excluding the effect that the Midpoint Peg Order itself has on the inside bid or inside offer. As the bids and offers change, so move the Pegged Orders. A Pegged Order may have a limit price beyond which the order shall not be executed. Primary Peg and Market Peg Orders may establish their pricing relative to the appropriate bids or offers by selecting one or more offset amounts that will adjust the price of the order by the offset amount selected.

Under the Exchange's current rule, Midpoint Pegged Orders are not displayed, while Primary and Market Pegged Orders may be displayed or not displayed, at the option of the person placing the order. The display of Primary Pegs with an offset amount can potentially result in excessive messaging when multiple venues display Pegged non-marketable Orders. In these scenarios, it is possible for the Primary Pegged Orders on each venue to react to and change in relation to each other, resulting in excessive messaging and “quote flickering.” A rule change to eliminate display of Primary Pegged Orders with an offset amount will prevent this feedback loop, adding to system stability and improving market quality.

Market participants retain the ability to display orders through other order options available under the Exchange rules, including by using Primary Pegged Orders without an offset amount or Market Pegged Orders. Because Primary Pegged Orders without an offset amount are priced at the inside quote, they do not present the same messaging problem. Rapid updates to displayed Primary Pegged Orders may still occur, but are more likely to be the result of rapid trading. Market Pegged Orders, in contrast to Primary Pegs with an offset amount, are typically priced to execute and rarely post, and thus also do not present the excessive messaging problem.

The Commission approved the non-display of Pegged Orders when it approved the application of BATS Exchange, Inc. (“BATS”), for registration as a national securities exchange and found BATS' proposed rules consistent with Section 6 of the Act. BATS Rule 11.9(c)(8) provides that Pegged Orders “are not displayed on the Exchange.”

2. Statutory Basis

The proposed rule change is consistent with Section 6(b) of the Act, in general, and furthers the objectives of Section 6(b)(5), in particular, in that it is 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 facilitating transactions in securities, and to remove impediments to and perfect the mechanism of a free and open market and a national market system. Non-display of Primary Pegged Orders with an offset amount will minimize excess messaging that distracts from, rather than improves transparency and stability. Market participants can elect to display orders by using other available order types. The Exchange believes that the proposed change to Rule 3301(f)(4) meets the requirements of Section 6(b)(5) of the Act in that it will improve the stability, quality and transparency of the national market system.

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. Specifically, the Exchange believes that providing for non-display of Primary Pegged Orders will not burden competition since at least one other exchange currently offers the same attribute for pegged orders.

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

Because the foregoing 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 after the date of the filing, 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.

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 to determine whether the proposed rule should be approved or disapproved.
