Nasdaq
A computerized system that facilitates trading and provides price quotations on more than 5,000 of the more actively traded over the counter stocks. Created in 1971, the Nasdaq was the world's first electronic stock market.
Stocks on the Nasdaq are traditionally listed under four or five letter ticker symbols. If the company is a transfer from the New York Stock Exchange, the symbol may be comprised of three letters.

The term "Nasdaq" used to be capitalized "NASDAQ" as an acronym for National Association of Securities Dealers Automated Quotation. The acronym is no longer used and Nasdaq is now a proper noun.
The Nasdaq is traditionally home to many high-tech stocks, such as Microsoft, Intel, Dell and Cisco.
