          - [Release No. 34-43444; File No. SR-CHX-00-32] 

                    Pursuant to section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”),[1]                                          and Rule 19b-4 thereunder,[2]                                          notice hereby is given that on October 10, 2000, the Chicago Stock Exchange, Incorporated (“CHX” 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 Exchange has designated the proposed rule change as constituting a “non-controversial” rule change under paragraph (f)(6) of Rule 19b-4 under the Act,[3]                                          which renders the proposal effective upon receipt of this filing by the Commission.[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

The Exchange proposes to amend the CHX rule governing automatic execution of orders for NASDAQ/NM issues. Specifically, the Exchange proposes to amend CHX Article XX, Rule 37(b)(7)(ii), to provide order-sending firms with the option to select partial automatic execution of orders that are larger than the specialist's auto-execution threshold in instances where a specialist's quote is away from the national best bid or offer (“NBBO”). The text of the proposed rule change is available at the Commission or the CHX.

## 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 regarding the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. The Exchange prepared summaries, set forth in Section 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 Exchange proposes to amend the CHX rules governing the execution of NASDAQ/NM Securities. Specifically, the Exchange proposes to amend CHX Article XX, Rule 37(b)(7)(ii) to give order-sending firms the option to receive partial automatic executions if their orders are larger than the specialist's auto-execution threshold when the specialist's quote is away from the NBBO, or have these orders manually executed in their entirety as they are handled under the current rule. The proposed amendments are intended to bring the Exchange's rules in line with the practices that currently exist in other markets with respect to the trading of NASDAQ/NM Securities.                          ( print page 63274)    

                    CHX Article XX, Rule 37, commonly referred to as the “BEST Rule,” among other things, guarantees automatic executions if an order falls within certain size parameters,                     *i.e.,*                     the auto-acceptance threshold and the auto-execution threshold. The auto-execution threshold is an order size designated by the specialist for each issue, up to which size orders will be executed automatically at the NBBO.[5] 

CHX Article XX, Rule 37(b)(7)(ii) currently provides that in instances where a NASDAQ/NM specialist's quote is not at the NBBO, an order that is of a size greater than the auto-execution threshold for the security will not be automatically executed, but will be filled manually in accordance with the specialist's obligations under the BEST Rule, and the manual handling requirements of CHX Rule 43(d) of Article XX.

                    Some of the Exchange's order-sending firms believe that prompt execution of “partial fills” may be advantageous for their customers in many instances. Therefore, the Exchange proposes this rule change to provide an alternative to these firms that would permit partial automatic executions of orders larger than the specialist's auto-execution threshold, upon the election of an order-sending firm. Amended CHX Rule 37(b)(7) would provide that in instances where a NASDAQ/NM specialist's quote is not at the NBBO, an order that is of a size greater than the auto-execution threshold for the security will be designated as an open order and filled manually in accordance with he specialist's obligations under the BEST Rule and the manual handling requirements of Rule 43(d) of Article XX, unless the customer sending the order previously has indicated its election to have such orders filled on a partial basis,                     *i.e.,*                     filled automatically up to the auto-execution threshold, with the balance of the order to be designated as an open order.                

The Exchange believes that the proposed rule change is to the advantage of those order-sending firms and their customers that have a strong preference for quick executions even in circumstances where less than the entire order is confirmed as filled. As set forth above, the foregoing rule change is intended to place the Exchange's rules in line with existing market practice relating to the trading of NASDAQ/NM Securities. The proposed rule change thus necessarily contemplates certain distinctions between transactions in Dual Trading System issues and NASDAQ/NM issues. The Exchange's Rules Committee and its Committee on Floor Procedure, both of which are populated by specialists in both issues, approve all such distinctions. Both committees concur that the proposed rule change does not place specialists on unequal footing based on the type of issue traded, but merely reflects the distinctions between the markets for Dual Trading System issues and NASDAQ/NM issues.

#### 2. Statutory Basis

                    The proposed rule change is consistent with the requirements of the Act and the rules and regulations thereunder that are applicable to a national securities exchange, and, in particular, with the requirements of section 6(b).[6]                                          In particular, the proposed rule change is consistent with section 6(b)(5) of the Act [7]                                          in that it is designed to promote just and equitable principles of trade, to remove impediments and to perfect the mechanism of a free and open market and a national market system, and, in general, to protect investors and the public interest.                

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

The Exchange does not believe that the proposed rule change will impose any inappropriate burden on competition.

### C. Self-Regulatory Organization's Statement on Comments Regarding 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

                    The proposed rule change has been filed by the Exchange as a “non-controversial” rule change pursuant to section 19(b)(3)(A) of the Act [8]                                          and subparagraph (f)(6) of Rule 19b-4 thereunder.[9]                                          The proposed rule change: (i) Does not significantly affect the protection of investors or the public interest; (ii) does not impose any significant burden on competition; and (iii) does not become operative until thirty days after the date of filing, or such shorter time as the Commission may designate if consistent with the protection of investors and the public interest, provided that the Exchange has given the Commission written notice of its intent to file the proposed rule change, along with a brief description and text of 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 Exchange has requested that the Commission accelerate the operative date of the proposal. In addition, the Exchange provided the Commission with written notice of its intent to file the proposed rule change, along with a brief description and text of the proposed rule change, more than five business days prior to the date of the filing the proposed rule change.

                    The Commission finds that it is appropriate to accelerate the operative date of the proposal and designate the proposal to become operative today.[10]                                          The Commission finds that it is appropriate to accelerate the operative date of the proposed rule change because the change will provide investors who have a preference for quick executions the efficiency of automatic execution, even in circumstances where less than the entire order is confirmed as filled. For this reason, and because use of the partial execution feature is completely voluntary on the part of investors, the Commission finds that designation of the proposal to become operative today is consistent with the protection of investors and the public interest. Further, the Commission expects that with the advent of this proposed rule, more investors will receive executions at the NBBO because they will be able to elect to receive automatic executions that are guaranteed to be at the NBBO, instead of relying entirely on less certain manual executions.                

At any time within 60 days of the filing of the 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 Act. 

## IV. Solicitation of Comments

                    Interested persons are invited to submit written data, views and arguments concerning the foregoing, including whether the proposed rule change is consistent with the Act. Persons making written submissions should file six copies thereof with the Secretary, Securities and Exchange                           ( print page 63275)                        Commission, 450 Fifth Street, NW., Washington, DC 20549-0609. Copies of the submission, all subsequent amendments, all written statements with respect to the proposed rule change that are filed with the Commission, and all written communications relating to the proposed rule change between the Commission and any person, other than those that may be withheld from the public in accordance with the provisions of 5 U.S.C. 552, will be available for inspection and copying at the Commission's Public Reference Room. Copies of the filing will also be available for inspection and copying at the principal office of the Exchange. All submissions should refer to File No. SR-CHX-00-32 and should be submitted by November 13, 2000.                

                        For the Commission, by the Division of Market Regulation, pursuant to delegated authority.[11]

Deputy Secretary.
