Based on the total market capitalization of its listed securities, the New York Stock Exchange (NYSE) is the world's largest equity-based exchange. It is headquartered in New York City. On March 8, 2006, the NYSE went public after acquiring the electronic trading exchange Archipelago. When Euronext, Europe's largest stock exchange, merged with NYSE Euronext in 2007, NYSE Euronext was formed. The New York Stock Exchange's parent company, ICE, purchased NYSE Euronext and now owns the New York Stock Exchange.
The New York Stock Exchange (NYSE) has two trading floors: one for stocks and one for the NYSE American options exchange. It is located on Wall Street in New York. In 1978, both the main building at 18 Broad St. and the one at 11 Wall St. were designated historic. The NYSE is the world's largest stock exchange in terms of market capitalization, with a market capitalization of $26.64 trillion in August 2021.
For many years, the NYSE was solely reliant on floor trading via the open outcry system. Many NYSE trades have been shifted to electronic platforms, with designated market makers (DMMs) primarily in charge of both physical and automated auctions.
The New York Stock Exchange is now open from 9:30 a.m. to 4:00 p.m. ET. Some US holidays cause the stock exchange to close. The New York Stock Exchange may be closed on the Friday before certain events. The NYSE may be closed on Monday if a holiday falls on a Sunday.
