The National Association of Securities Dealers Automated Quotation system, is one of the largest markets in the world for the trading of stocks. 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 businesses. Trading on NASDAQ is initiated by stock brokers acting on behalf of their clients. The brokers negotiate with market makers who concentrate on trading specific stocks to reach a price for the stock.

納斯達克（NASDAQ）是全美證券交易協會自動報價系統的首字母縮略詞。它是當今世界上的股票交易市場之一。納斯達克（NASDAQ）名下的上市公司在數量上超過了包括紐約證券交易所（NYSE）和美國證券交易所（AMEX）在內的任何一家美國證券交易所。與紐約證券交易所（NYSE）和美國證券交易所（AMEX）的多數上市公司相比，在納斯達克（NASDAQ）上市的大多數公司規模較小。納斯達克（NASDAQ）已經成為新技術公司——尤其是計算機和與計算機相關行業——的基地。納斯達克（NASDAQ）的交易是通過代表客戶利益的股票經紀人發起的。這些經紀人與專注特定股票買賣的市場期票出票人進行協商以確定股票的價格。

Unlike other stock exchanges, NASDAQ has no central location where trading takes place. Instead, its market makers are located all over the country and make trades by telephone and via the Internet. Because brokers and market makers trade stocks directly instead of on the floor of a stock exchange, NASDAQ is called an 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.

與其他證券交易有所不同，納斯達克（NASDAQ）沒有股票交易的中心交易場所。它的市場期票出票人遍及全美各地，通過電話和國際互聯網進行交易。由于股票交易是由經紀人和市場期票出票人直接進行，而不是在股票交易大廳內進行的，困此，納斯達克（NASDAQ）被稱為買賣雙方直接交易市場。該術語指出了其交易的直接性質，就如同在商店柜臺直接進行商品的買賣一樣。

Now poised to become the world”s first truly global market, the NASDAQ Stock Market is the market of choice for business industry leaders worldwide.
