Self-Regulatory Organizations; Chicago Board Options Exchange, Incorporated; Notice of Filing and Immediate Effectiveness of a Proposed Rule Change To Clarify That CBSX Will Process Only Round-Lot Orders of HOLDRS

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 November 15, 2011, the Chicago Board Options Exchange, Incorporated (“Exchange” or “CBOE”) 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 amend Rule 52.8 to clarify that CBOE Stock Exchange (“CBSX”), CBOE's stock trading facility, will only process round-lot orders of HOLDRS Trust Issued Receipts (“HOLDRS”) that trade on CBSX. The text of the proposed rule change is available on the Exchange's Web site ( http://www.cboe.com/AboutCBOE/CBOELegalRegulatoryHome.aspx ), at the Exchange's Office of the Secretary, and at the Commission.

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 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 the Statutory Basis for, the Proposed Rule Change

1. Purpose

Rule 52.8 states that odd-lot orders (including the odd-lot potion of a mixed-lot order) are processed in the same manner as are round-lot orders, except (i) If an incoming odd-lot order trades against a quote in the CBSX Book, the new quantity remaining in the quote will be rounded down to the nearest lower round-lot amount (zero or multiple of 100) for display purposes, with the remaining odd-lot amount being cancelled, or (ii) if an incoming order trades against a limit order resting on the CBSX Book and an odd-lot amount remains from the limit order resting on the CBSX Book, that odd-lot amount will remain in the system eligible for execution but will not be displayed.

HOLDRS are Trust Issued Receipts that trade on CBSX and represent an investor's beneficial ownership of a specified group of stocks in various industries, sectors or groups. Currently, CBSX processes odd-lot and mixed-lot orders of HOLDRS in accordance with Rule 52.8, as described above. However, the prospectuses describing the terms of HOLDRS provide that investors may only acquire, hold, transfer, and surrender a round-lot of HOLDRS. The purpose of the proposed rule change is to amend Rule 52.8 to state that CBSX will only process round-lot orders of HOLDRS that trade on CBSX in accordance with the trading terms of HOLDRS. CBSX will no longer accept odd-lot or mixed-lot orders of HOLDRS it receives.

2. Statutory Basis

The Exchange believes 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 and to promote just and equitable principles of trade, and in general to protect investors and the public interest. Specifically, the Exchange believes that the proposed rule change serves to foster investor protection by ensuring that investors not only are aware of this restriction on transactions in HOLDRS but also comply with this restriction going forward, as CBSX will no longer accept transactions that do not.

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

CBOE 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.

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

No written comments were solicited or received with respect to the proposed rule change.

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

The foregoing rule change has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) thereunder because the proposal does not: (i) Significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) by its terms, become operative for 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 Exchange has requested that the Commission waive the 30-day operative delay period. The Commission believes that such action is consistent with the protection of investors and the public interest, because it will enable the Exchange immediately to align its trading rules with respect to HOLDRS with provisions of the HOLDRS prospectuses. Therefore, the Commission 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.
