Cincinnati Stock Exchange |
The National Stock Exchange (NSX) is an electronic stock exchange located in Chicago, Illinois. It was founded in 1885 in Cincinnati, Ohio, as the Cincinnati Stock Exchange.1 In 1976, it closed its physical trading floor and became an all-electronic stock market. The Cincinnati Stock Exchange moved its headquarters to Chicago in 1995, and changed its name to the National Stock Exchange in November 7, 2003.2 It was formerly a subsidiary of the Chicago Board Options Exchange.3
The National Stock Exchange is said to handle 20% of all trading in NASDAQ-listed issues.
Two previous exchanges, both located in New York City, operated under the National Stock Exchange name. One existed briefly in 1869; the other, owned by the New York Mercantile Exchange, traded from about 1962 to 1974.
