In-depth Analysis of the Three Major U.S. Stock Exchanges

The U.S. stock market is composed of three main exchanges, each operating independently with distinct trading rules, stock compositions, and market characteristics.

New York Stock Exchange (NYSE)

Founded on May 17, 1792, when 24 brokers and merchants signed the “Buttonwood Agreement under a Buttonwood Tree at 68 Wall Street,” laying the foundation for modern securities trading. Based on total market capitalization of listed companies, NYSE is now the world’s largest stock exchange. Trading has largely transitioned to electronic systems, but floor trading remains important for price discovery and large institutional transactions.

NASDAQ Stock Market (NASDAQ)

NASDAQ is the second-largest securities exchange globally and the first fully electronic stock market in the world. Unlike NYSE’s reliance on trading floors, NASDAQ allows investors to trade directly via phone or internet. Known for listing high-tech companies, giants like Microsoft and Apple are listed here. Compared to other exchanges, NASDAQ’s stock composition is more concentrated in technology stocks, forming a clear tech cluster.

American Stock Exchange (AMEX)

Ranking third among U.S. stock exchanges after NYSE and NASDAQ, AMEX’s trading mechanism is similar to NYSE but with distinct features—mainly handling small- and mid-cap stocks. It is the only U.S. exchange that trades stocks, futures, and derivatives simultaneously, offering diversified asset allocation options.
