Founded in 1899, in 1900 the name was changed to the Los Angeles Stock Exchange.

[1] During the early development of the Los Angeles City Oil Field, no single firm had a dominant share.

Drillers started their own companies, flooding the local stock exchange with shares of start-up oil firms.

[2] The Exchange changed locations frequently in its early years, until finally locating to 618 South Spring Street in downtown Los Angeles in 1931 in the Los Angeles Stock Exchange Building, remaining there until February 1986.

Needing more space, the trading floor was moved to the Pacific Stock Exchange building at 233 South Beaudry Avenue, but it was closed in May 2001.
