The New York Stock Exchange (NYSE) is one of the world's largest stock exchanges. With the acquisition of Archipelago (electronic trading exchange) on March 8, 2006, the New York Stock Exchange became a public institution. After merging with Euronext, the largest stock exchange in Europe, in 2007, NYSE Euronext was established. NYSE Euronext was taken over by Intercontinental Exchange (ICE), the current parent company of the New York Stock Exchange.

NYSE is located on Wall Street in New York City. Two trading floors are available on the NYSE, one for stocks and one for American Options Exchange. The main buildings of the NYSE (18 Broad St. and 11 Wall St.) have been classified as historical landscapes since 1987. In August 2021, the NYSE was estimated to have a market capitalization of $26.64 trillion, making it the world's largest stock exchange by market capitalization.

New York Stock Exchange trades are conducted in a continuous auction. The NYSE is well known for its floor trading. Today, the majority of NYSE stock transactions are carried out electronically, which means that buyers and sellers are matched electronically. More about the price mechanism can be found in the article on supply and demand. Even though most transactions are now conducted electronically, the New York Stock Exchange continues to operate as a hybrid market. In this manner, stock brokers can send orders either electronically or directly to the trading floor, where they will be executed by floor traders.


In terms of equity trading volume from January to December 2019, the NYSE was ranked among the top three exchanges in the world:

Trading began and ended with the sound of a gong on the NYSE originally. A Chinese gong was introduced in 1870. The gong was replaced with a brass bell when it was relocated to its current location. Opening bells are rung at 9:30 AM Eastern Time, and closing bells are rung at 4:00 PM Eastern Time. There are certain U.S. holidays on which the exchange is closed. NYSE sometimes closes the Friday before these holidays when they fall on a Saturday. In the event that the holiday falls on a Sunday, the NYSE may be closed on Monday.


The opening and closing bells play an important role in marking financial events as well as celebrating important events that take place in New York City. The opportunity to ring the NYSE bell is an honor. The bell is rung by a wide variety of people, including business leaders and celebrities. The New York City Police and Fire Departments were also granted this privilege during the September 11, 2001 attacks.

At 68 Wall Street, in 1792, 24 brokers and merchants signed the Buttonwood Agreement, which established the rules for securities trading. Originally, the organization was known as the New York Stock & Exchange Board. In 1863, the current name was adopted. There were only male traders participating in the NYSE at that time. Muriel Siebert was the first female trader to be allowed to participate in trading in 1967.


The NYSE became a non-profit company in 1971, and a publicly traded company in 2006. Trading stocks began to be conducted electronically during this period. Following the merger with Euronext in 2007, the NYSE acquired the American Stock Exchange in 2008. In later years, the Intercontinental Exchange acquired the NYSE for $8.2 billion.
