Manhattan: Financial District/
Broad St. between Wall St. and Exchange Pl.
While business was being conducted inside the New York Stock Exchange building, non-member brokers were outside at the curb, dealing in stocks that didn't meet the NYSE's requirements. The group was organized as the New York Curb Market Agency in 1908. They moved indoors in 1921, became the New York Curb Exchange in 1929, and rebranded as the American Stock Exchange (Amex) in 1953. NYSE and Amex merged in 2008 and the Amex trading floor was moved back to the NYSE building (this time indoors).
