American Stock Exchanger
American Stock Exchange® (AMEX®, ASE)
A large floor-based securities exchange in New York City that provides facilities for trading stocks, bonds, index shares, and equity derivative securities. Listing requirements for stocks are less stringent than those of the New York Stock Exchange, resulting in the AMEX trading securities of younger and smaller firms with fairly volatile price movements. The American Stock Exchange has been a leader in introducing new investment products such as exchange-traded funds. See also Curb Exchange.
