New York Stock Exchange

The oldest securities exchange in the United States and the largest in the world by dollar value. Founded in 1792, it merged with Euronext in 2007 to form NYSE Euronext, which operates the exchange. Equities in 3,000 companies and 2,000 bonds are traded on the NYSE floor, with a market capitalization of $10.1 trillion in October 2008. The exchange operates as an auction, in which potential buyers and sellers gather around an appropriate floor specialist, who is employed by an NYSE member firm (not the NYSE itself) and who acts as an auctioneer to the buyers and sellers, who attempt to buy at the lowest possible price or sell at the highest. The right to trade on the floor belongs to any one of the owners of the 1366 seats on the exchange floor.

What Does New York Stock Exchange (NYSE) Mean?

Located in New York City, it is considered the largest equities-based exchange in the world, based on the total market capitalization of its listed securities. Formerly run as a private organization, the NYSE became a public entity in 2005 after the acquisition of the electronic trading exchange Archipelago. The parent company of the New York Stock Exchange is now called NYSE Euronext after a merger with the European exchange in 2007. Also known as the Big Board, the NYSE relied for many years on floor trading by “specialists” only, using the open outcry system. Today, more than half of all NYSE trades are conducted electronically, although floor traders still are used to facilitate liquidity and execute high-volume institutional trading.
