The third-largest stock exchange by trading volume in the United States. The AMEX is located in New York City and handles about 10% of all securities traded in the U.S.
Investopedia Says:
The AMEX has now merged with the Nasdaq. It was known as the "curb exchange" until 1921.
It used to be a strong competitor to the New York Stock Exchange, but that role has since been filled by the Nasdaq. Today, almost all trading on the AMEX is in small-cap stocks, exchange-traded funds and derivatives.
