Start Preamble April 26, 2000.

On December 10, 1999, the New York Stock Exchange, Inc. (“NYSE” or “Exchange”) filed with the Securities and Exchange Commission (“SEC” or “Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Exchange Act”) [1] and Rule 19b-4 thereunder,[2] a proposed rule change to rescind Exchange Rule 390. The proposed rule change was published for comment in the Federal Register on February 28, 2000.[3] The release publishing notice of the proposed rule change also included a Commission request for public comment on issues relating to market fragmentation (“Concept Release”). The comment period relating to the rescission of Exchange Rule 390 expired on March 20, 2000; the comment period for issues related to market fragmentation is scheduled to expire on April 28, 2000.

The Commission has decided to extend for two weeks until May 12, 2000, the comment period for issues related to market fragmentation. The Concept Release requested comment on a wide range of issues, including whether fragmentation is now, or may become in the future, a problem that significantly detracts from the fairness and efficiency of the U.S. markets. In addition, the Concept Release requested comment on six potential options for addressing fragmentation. These issues are very complex, and the Commission believes that it will be helpful for commenters to have two extra weeks in which to prepare and submit their views.

In this regard, the Commission urges commenters not to limit their attention to a single option raised in the Concept Release, particularly the option of establishing comprehensive price/time priority for all displayed trading interest. This option has been widely referred to in the press as a “CLOB”—a central limit order book. The other five options were included in the Concept Release specifically to afford commenters an opportunity to submit their views on alternatives to a CLOB that would be more focused on specific practices or problems that may isolate investor orders, discourage quote competition, or impair public price discovery. The Commission hopes to receive the benefit of commenters' views on these other options as well.

Interested persons are invited to submit written data, views, and arguments concerning issues relating to market fragmentation discussed in the Concept Release. Persons making written submissions should file six copies thereof with the Secretary, Securities and Exchange Commission, 450 Fifth Street, NW, Washington, DC 20549-0609. Comments also may be submitted electronically at the following E-mail address: All comment letters should refer to File No. SR-NYSE-99-48. Comments submitted by E-mail should include this file number in the subject line. Comment letters received will be available for public inspection and copying in the Commission's Public Reference Room. Electronically submitted comment letters will be posted on the Commission's Internet web site (

It is therefore ordered that the period for public comment on issues relating to market fragmentation is extended until May 12, 2000.
