Definition of NYSE

---

The New York Stock Exchange (NYSE), nicknamed the "Big Board", is a New York City-based stock exchange. It is the largest stock exchange in the world by dollar volume and, with 2,764 listed securities[1], has the second most securities of all stock exchanges. Its share volume was exceeded by that of NASDAQ during the 1990s. Nontheless, the NYSE constitutes the biggest and most crucial financial hub of the world, along with Tokyo Stock Exchange and London Stock Exchange. As of December 31, 2006, the combined capitalization of all New York Stock Exchange listed companies was $25.0 trillion. [2]

The NYSE is operated by NYSE Euronext, which was formed by its merger with the fully electronic stock exchange Archipelago Holdings and Euronext. The New York Stock Exchange trading floor is located at 11 Wall Street, and is composed of four rooms used for the facilitation of trading. A fifth trading room, located at 30 Broad Street, was closed in February 2007. The main building, located at 18 Broad Street between the corners of Wall Street and Exchange Place, was designated a National Historic Landmark in 1978.[3]

NYSE Group merged with Euronext, and many of its operations (particularly IT and the trading platform) will be combined with that of the New York Stock Exchange and NYSE Arca.
