Pacific Stock Exchange Los Angeles

The Pacific Stock Exchange is one of the smaller regional stock exchanges with a main exchange floor and building in San Francisco, California and a branch in Los Angeles, California, United States. It was set up in 1882 as the San Francisco Stock and Bond Exchange. In 1957 the two exchanges, San Francisco and Los Angeles exchanges, merged to form the Pacific Coast Stock Exchange.

In 2001 the trading floor in Los Angeles was closed, and in 2002 the San Francisco trading floor was closed as well. Pacific Stock Exchange shares trading now occurs solely through NYSE Arca (formerly known as ArcaEx), an electronic communications network (ECN).

In 2003 the Pacific Stock Exchange introduced the PCX Plus, an electronic options dealing platform.

The Pacific Exchange was acquired by Archipelago Holdings in 2005, and later it was acquired by the New York Stock Exchange in 2006, essentially ending its run as a separate identity.
