New York Stock Exchange

The New York Stock Exchange (NYSE), nicknamed the "Big Board", is the world's largest stock exchange by market capitalization of its listed companies. Located at 11 Wall Street in the Financial District of Manhattan, New York City, the exchange traces its origins to the Buttonwood Agreement of 1792, when 24 stockbrokers agreed to trade securities under a buttonwood tree on Wall Street. The NYSE was formally organized as the New York Stock & Exchange Board in 1817 before adopting its current name in 1863. Today, the exchange is operated by NYSE Group, a subsidiary of Intercontinental Exchange (ICE).

The NYSE provides a regulated marketplace for the listing and trading of equities, exchange-traded funds (ETFs), closed-end funds, and other securities issued by domestic and international companies. It employs a hybrid market model that combines electronic trading with designated market makers (DMMs), who help maintain orderly markets and provide liquidity. The exchange lists many of the world's largest corporations across sectors including finance, technology, healthcare, energy, consumer goods, and industrial manufacturing. Major market indices associated with NYSE-listed companies include the Dow Jones Industrial Average, the S&P 500, and the NYSE Composite Index.

The NYSE plays a central role in the global financial system by facilitating capital formation, price discovery, and investment. It is subject to regulation by the U.S. Securities and Exchange Commission (SEC) and is a member of the World Federation of Exchanges (WFE). The exchange maintains stringent listing, disclosure, and corporate governance requirements designed to protect investors and promote market integrity. Its iconic trading floor and historic headquarters building have become enduring symbols of the United States capital market and international finance.
