New York Stock Exchange and NASDAQ
The New York Stock Exchange traces its origins back more than 200 years, to the signing of the Buttonwood Agreement by 24 New York City stockbrokers and merchants in 1792. The NYSE registered as a national securities exchange with the U.S. Securities and Exchange Commission on October 1, 1934. One of its increasingly unique features is that it still practices the open outcry system of trading. NASDAQ, on the other hand, is an electronic quotation system that provides price quotations to market participants about more actively traded common stock issues in the over the counter market. About 4000 common stock issues are included in the NASDAQ system. The Nasdaq Stock Market made its debut in 1971 as the world's first electronic stock market. Trades are executed though a sophisticated computer and telecommunications network.
