NYSE
The New York Stock Exchange (NYSE) is the world's largest stock exchange by market capitalization, located on Wall Street in New York City, where shares of thousands of U.S. and international corporations are listed and traded. Founded in 1792, the NYSE is operated by Intercontinental Exchange (ICE) and is regulated by the SEC.
The New York Stock Exchange has a history stretching back to May 17, 1792, when 24 stockbrokers signed the Buttonwood Agreement under a buttonwood tree on Wall Street, establishing a formal market for trading securities. Over the following two centuries, the NYSE grew into the financial hub of the United States and the world, listing iconic American corporations such as General Motors, Coca-Cola, JPMorgan Chase, and ExxonMobil.
The NYSE is a hybrid market, meaning it combines electronic trading with a traditional specialist (now called 'designated market maker' or DMM) system on the trading floor. DMMs are firms responsible for maintaining fair and orderly markets in specific stocks assigned to them. They facilitate trading by quoting both bid and ask prices and stepping in with their own capital during periods of extreme volatility or thin liquidity — a role that proved critical during the market turbulence of March 2020 when the COVID-19 pandemic caused historic single-day price swings.
Listings on the NYSE are considered a mark of corporate prestige and stability. To be listed, companies must meet stringent financial thresholds set by the exchange, including minimum earnings, market capitalization, and corporate governance standards. The SEC provides additional oversight, requiring all NYSE-listed companies to file regular disclosures including 10-K annual reports, 10-Q quarterly reports, and 8-K current reports for material events.
The NYSE trading session runs from 9:30 a.m. to 4:00 p.m. Eastern Time on regular business days. The exchange is closed on federal holidays and occasionally for extraordinary events — most notably, the NYSE was closed for four consecutive trading days following the September 11, 2001 terrorist attacks, the longest closure since the Great Depression. Circuit breakers, implemented following the 1987 Black Monday crash, can now halt trading temporarily when the market falls sharply within a single session.
For educational purposes, investors should understand that while the NYSE floor still exists and is broadcast in financial media, the vast majority of NYSE-listed trades are executed electronically. The physical floor's symbolic importance, however, endures — it is where IPO bell-ringing ceremonies take place, serving as a visible marker of a company's transition to public ownership.
