National Stock Exchange Files With SEC to Halt Operations (original) (raw)

The National Stock Exchange, an equity trading venue with about 0.2 percent of U.S. volume, has filed with the Securities and Exchange Commission to cease operations on May 30, according to its website.

Closing the market, also known as NSX, would cut the number of public stock exchanges in the U.S. to 11, and would come one month after CBOE Stock Exchange closed. That venue, which is partially owned by CBOE Holdings Inc., owns NSX.
