          - [Release No. 34-62170; File No. SR-CBOE-2010-048]

                    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”),[1]                                          and Rule 19b-4 thereunder,[2]                                          notice is hereby given that on May 19, 2010, the Chicago Board Options Exchange, Incorporated (“Exchange” or “CBOE”) filed with the Securities and Exchange Commission (the “Commission”) the proposed rule change as described in Items I, II, and III below, which Items have been prepared by the Exchange. The Exchange filed the proposal as a “non-controversial” proposed rule change pursuant to Section 19(b)(3)(A)(iii) of the Act [3]                                          and Rule 19b-4(f)(6) thereunder.[4]                                          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

                    CBOE proposes to modify its rules to permit the Exchange, on any Thursday or Friday, to open Short Term Option Series that expire on the Friday of the following business week. The Exchange is not proposing any rule text changes. The rule proposal is available on the Exchange's Web site (                    *http://www.cboe.org/​legal*), 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 Statutory Basis for, the Proposed Rule Change

#### 1. Purpose

                    The Securities and Exchange Commission previously approved CBOE's proposed rule change to permanently establish the Short Term Option Series Pilot Program (“Program”).[5]                                          The Program allows CBOE to list and trade equity and index option series that expire one week after being opened for trading. Specifically, Rules 5.5(d) and 24.9 provide that, after an option class has been approved for listing and trading on the Exchange, the Exchange may open for trading on any Friday that is a business day series of options on that class that expire on the next Friday that is a business day.[6]                                          Under the Program, CBOE may select up to five approved option classes on which Short Term Options Series may be opened. The Exchange has selected the following four option classes to participate in the Program: S&P 500 Index options (SPX), S&P 100 Index American-style options (OEX), Mini-S&P 500 Index options (XSP), and S&P 100 Index European-style options (XEO).                

The purpose of this filing is to permit the Exchange to open Short Term Option Series on any Thursday (or Friday) that expire on the Friday of the following business week. In support of this modification, the Exchange states that it has received requests to begin certain Short Term Options on Thursday so that market participants may have an opportunity to “roll” expiring positions; that is, trade out of an expiring Short Term Option Series and re-establish a new position in Short Term Option Series expiring one week later. Since the last trading day for A.M.-settled Short Term Options on indexes is generally a Thursday, and new A.M.-settled Short Term Option Series on indexes are generally listed on Friday, new and expiring A.M.-settled Short Term Option Series on indexes are never available concurrently.

As a result, it is impossible to implement a position roll in A.M.-settled Short Term Options on indexes. The Exchange has been advised that opening A.M.-settled Short Term Options on indexes just one day earlier, and providing an opportunity to roll, would enhance the value A.M.-settled Short Term Options on indexes as a risk management tool.

In order to avoid investor confusion, the Exchange is proposing to permit the listing of all Short Term Option series (equity and index) on any Thursday or Friday. As proposed, the rule changes give the Exchange the flexibility to list Short Term Option series on any Thursday or Friday, and do not restrict listing to a particular day.

#### 2. Statutory Basis

                    The Exchange believes this rule proposal is consistent with the Act and the rules and regulations under the Act applicable to a national securities exchange and, in particular, the requirements of Section 6(b) of the Act.[7]                                          Specifically, the Exchange believes that the proposed rule change is consistent with the Section 6(b)(5) Act [8]                                          requirements that the rules of an exchange be designed to promote just and equitable principles of trade, to prevent fraudulent and manipulative acts and, in general, to protect investors and the public interest. In particular, the                           ( print page 30890)                        proposed rule change will benefit market participants by allowing them to more closely manage their risk exposures and carry out their investment objectives.                

### 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

                    Because the foregoing proposed rule 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 if consistent with the protection of investors and the public interest, provided that the self-regulatory organization has given the Commission written notice of its intent to file the proposed rule change at least five business days prior to the date of filing of the proposed rule change or such shorter time as designated by the Commission, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act [9]                                          and Rule 19b-4(f)(6) thereunder.[10]                                          At any time within 60 days of the filing of such proposed rule change, the Commission may summarily abrogate 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.                

## IV. Solicitation of Comments
