New York Stock Exchange (NYSE)

Trading Term

The New York Stock Exchange (NYSE) is a major stock exchange based in New York City. The NYSE is considered the largest equities-based exchange in the world based on total market capitalization of its listed securities. The NYSE became a public entity in 2005 after acquiring electronic trading exchange Archipelago. The parent company of the New York Stock Exchange is now called NYSE Euronext, following a merger with the European exchange in 2007. Also known as the “Big Board”, the NYSE relied for many years on floor trading only, using the open outcry system. Today, more than half of all NYSE trades are conducted electronically, although floor traders are still used to set pricing and deal in high volume institutional trading.
