2013-12437. Self-Regulatory Organizations; NASDAQ OMX PHLX LLC; Notice of Filing and Immediate Effectiveness of Proposed Rule Change To Amend Rule 3306 and Rule 3303 To Stipulate How Participants in NASDAQ OMX PSX May Modify Previously Entered ...

May 20, 2013.

Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”),^[1] and Rule 19b-4 thereunder,^[2] notice is hereby given that on May 10, 2013, NASDAQ OMX PHLX LLC (“Phlx” or “Exchange”) filed with the Securities and Exchange Commission (“SEC” or “Commission”) the proposed rule change as described in Items I, II, and III, 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 amend Rule 3306 (Entry and Display of Quotes and Orders) and Rule 3303 (Short Sale Price Test Pursuant to Rule 201 of Regulation SHO) to stipulate how Participants in NASDAQ OMX PSX (“PSX”) may modify previously entered orders and to describe how modified orders are processed. The text of the proposed rule change is below; proposed new language is italicized, and proposed deletions are in brackets.

3303. Short Sale Price Test Pursuant to Rule 201 of Regulation SHO

(a)-(c) No change.

(d) Re-pricing of Orders during Short Sale Period. Except as provided below, [D]d uring the Short Sale Period, short sale orders that are limited to the national best bid or lower and short sale market orders will be re-priced by the System one minimum allowable price increment above the current national best bid (“Permitted Price”). To reflect declines in the national best bid, the Exchange will continue to re-price a short sale order at the lowest Permitted Price down to the order's original limit price, or if a market order, until the order is filled. Non-displayed orders between the PSX bid and offer at the time of receipt will also be re-priced upward to a Permitted Price to correspond with a rise in the national best bid.

(1) No change.

(2) During the Short Sale Period, if an order was entered as a long sale order or a short sale exempt order but is subsequently marked pursuant to Phlx Rule 3306(a)(3) as a short sale order, the System will cancel the order unless it is priced at a Permitted Price or higher.

(e)-(f) No change.

* * * * *

3306. Entry and Display of Quotes and Orders

(a) Entry of Orders—Participants can enter orders into the System, subject to the following requirements and conditions:

(1)-(2) No change.

(3) Orders can be entered into the System (or previously entered orders cancelled or modified) from 8:00 a.m. until 5:00 p.m. Eastern Time. Participants may modify a previously entered order without cancelling it or affecting the priority of the order on the book solely for the purpose of modifying the marking of a sell order as long, short, or short exempt; provided, however, that if an order is redesignated as short, a Short Sale Period is in effect under Rule 3303, and the order is not priced at a Permitted Price or higher under Rule 3303(d), the order will be cancelled. In addition, a partial cancellation of an order to reduce its share size will not affect the priority of the order on the book. All other modifications of orders will result in the replacement of the original order with a new order with a new time stamp.

(b)-(c) No change.

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 purpose of the proposed rule change is to stipulate how Participants in PSX may modify previously entered orders and to describe how modified orders are processed. Currently, Rule 3306 permits previously entered orders to be cancelled, a fact that has been interpreted by Phlx to allow a Participant to cancel an order in full or in part. However, new language is being added to the rule to make it clear that a partial cancellation of an order (i.e., a reduction in the share size of the order) does not cause the order to lose priority on the PSX book. Phlx believes that it is reasonable to allow the partial cancellation of an order without the order losing priority because the Participant that entered the order continues to express its willingness to trade at the price entered when the order first came onto the book. Moreover, if the order is displayed, other Participants quoting at the same price are aware of the priority of their orders relative to the partially cancelled order. While a partial cancellation may provide these other Participants with greater opportunities to provide a fill, Phlx does not believe that it would be reasonable for the Participants to jump ahead of an order with time priority merely because the size of the order has been reduced. Similarly, if the partially cancelled order is non-displayed, other Participants would have no awareness of its price, its original size, or its reduced size. Again, while other Participants at that price may have an increased opportunity to provide a fill when the order's size is reduced, they would not have an expectation that the priority of their orders would change vis-à-vis that of an order that arrived on the book at an earlier time. Finally, with respect to Participants seeking to access liquidity, the reduced size of the order would be disseminated (if a displayed order) or not disseminated (if a non-displayed order) via market data feeds, but these Participants would be indifferent as to the order's priority vis-à-vis other orders with the same price.

In addition, Phlx is modifying Rule 3303 to provide that a sell order may be modified in order to change its marking as long, short, or short exempt without affecting its priority on the book.^[3] Participants sometimes wish to modify the marking of a sell order on the book due to changes in the Participant's holdings of the security in question. At present, such a modification may only be achieved by the cancellation of the existing order and its replacement with a new order with a different time stamp. Phlx believes that it is reasonable to allow the modification of an order for this purpose without affecting its priority, since the order's marking has no bearing on the timing of its entry onto the book vis-à-vis other orders at the same price.^[4] In the event, however, that a long or short exempt order is redesignated as a short sale order and the security that is the subject of the order is in a Short Sale Period, as provided for in Rule 3303 and Rule 201 under Regulation SHO,^[5] the order will be evaluated to determine whether its price would be a Permitted Price within the meaning of Rule 3303(d). If not, the order will be cancelled rather than repriced.^[6] Phlx believes that cancelling the order under these circumstances is preferable to repricing it, because it alerts the Participant entering the order to the existence of the Short Sale Period and forces the Participant to evaluate its intentions with regard to the order.

Finally, Phlx is amending Rule 3303 to make it clear that all other modifications of previously submitted orders, including increases in size ^[7] and changes in price, will result in the cancellation of the original order and its replacement with a new order with a new time stamp. Although the addition of this rule language does not reflect a change in the way the Phlx system currently operates, Phlx believes that the clarity of the rule will be enhanced by including the new language. Phlx further believes that the functionality described by the rule language is important to ensuring that Participants cannot use an existing order unfairly to retain priority with respect to a materially different order.

2. Statutory Basis

Phlx believes that its proposal is consistent with Section 6(b) of the Act ^[8] in general, and furthers the objectives of Section 6(b)(5) of the Act ^[9] 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. Specifically, Phlx believes that permitting Participants to change the marking of sell orders without affecting their priority on the Phlx book will eliminate an aspect of PSX that had unnecessarily made it more difficult for posted sell orders to execute. Thus, the change will enhance the fairness and efficiency of PSX without affecting the ability of Participants to comply with applicable regulatory requirements. In addition, the changes to the rule that describe the effect of a partial order cancellation promote the clarity of the rule with respect to the ability of a Participant to reduce the size of an existing order without affecting its priority. Phlx further believes that allowing an order to retain priority under these conditions is consistent with the operation of a free and open market and the protection of investors and the public interest, since the Participant that entered an order that is partially cancelled has nevertheless expressed a continued willingness to trade at a specified price, and therefore should retain priority over Participants that joined that price at a later time. Finally, Phlx believes that the proposed addition of language to clearly stipulate that all other order modifications will result in the cancellation and replacement of the original order with a new order with new time priority is consistent with the protection of investors and the public interest because the new language will make clear an existing feature of the market that Phlx believes is important to ensuring that Participants cannot use an existing order unfairly to retain priority with respect to a materially different order.

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

Phlx does not believe that the proposed rule change will result in any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act, as amended. Specifically, Phlx believes that the change with respect to allowing Participants to modify the long, short, or short exempt marking of a sell order without affecting its priority will assist Phlx in competing with the BATS Exchange and the BATS Y-Exchange, which already allow their Participants to do so. Phlx further believes that the other changes will not have any effect on competition.

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

No written comments were either solicited or 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 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)(ii) of the Act ^[10] and subparagraph (f)(6) of Rule 19b-4 thereunder.^[11] 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.
