Stock exchange in the U.S. Originally known as "the Curb," it began as an outdoor marketplace in New York City 0441; 1850.
It moved indoors to its present location in the Wall Street area in 1921. Once a marketplace for securities not reputable enough for the New York Stock Exchange , it became equally respectable, with its own listing admissions requirements. In 1998 it merged with the National Association of Securities Dealers (NASD), then-owner of the NASDAQ exchange, to form the Nasdaq-Amex Market Group. After NASD sold its interest in the NASDAQ in 2000, AMEX remained a NASD subsidiary.
