NASDAQ, standing for the National Association of Securities Dealers Automated Quotation system, is one of the largest markets in the world for the trading of stocks（股票）. The number of companies listed on NASDAQ is more than that on any of the other stock exchanges in the United States, including the New York Stock Exchange （NYSE）,and the American Stock Exchange （AMEX）.The majority of companies listed on NASDAQ are smaller than most of those on the NYSE and AMEX. NASDAQ has become known as the home of new technology companies, particularly computer and computer-related business. Trading on NASDAQ was started by stock brokers acting on behalf of their customers. The brokers talk with market makers who devote themselves to trading specific stocks to reach a price for the stock.

Unlike other stock exchanges, NASDAQ has no central place where trading takes place. Instead, its market makers are located all over the country and make trades by telephone and the Internet. Because brokers and market makers trade stocks directly instead of on the floor of a stock exchange, NASDAQ is called over-the-counter market. The term over-the-counter refers to the direct nature of the trading, as in a store where goods are handed over a counter.

Since its birth in 1971,the NASDAQ Stock Market has been an industry innovator（革新者）.As the world’s first electronic stock market, NASDAQ long ago started technological trading innovation that is unequalled. Now becoming the world's first truly global market, the NASDAQ Stock Market is the market of choice for business industry leaders worldwide. By providing an efficient environment for raising capital（资本）, NASDAQ helped thousands of companies get their desired growth and successfully make the jump into public ownership.
