Pacific Stock Exchange

The Pacific Exchange was a regional stock exchange located in San Francisco, California, USA. Its history began with the founding of the San Francisco Stock and Bond Exchange in 1882. Seven years later, the Los Angeles Oil Exchange was founded. In 1957, the two exchanges merged to form the Pacific Coast Stock Exchange, though trading floors were kept in both cities. A name change to the Pacific Stock Exchange took place in 1973. Options trading began three years later. In 1997, "Stock" was dropped from the exchange's name.
