Introduction to the Three Major US Stock Exchanges

New York Stock Exchange (NYSE)

The NYSE is the world’s largest stock exchange by total market capitalization of listed securities. It lists over 3,500 stocks, including many blue-chip and traditional industry leaders. Today, trading is mainly electronic, but floor trading still plays an important role in large institutional transactions and price discovery.

NASDAQ Stock Market

NASDAQ is the world’s first fully electronic securities market, where investors mainly trade via phone or internet. It features many high-tech companies, including Microsoft, Apple, and other tech giants. The core difference between NASDAQ and NYSE lies in its fully electronic trading system and the industry characteristics of its listed companies.

American Stock Exchange (AMEX)

The AMEX is the third-largest trading market in the US. After 2008, it was incorporated into NYSE and is now called NYSE American. It mainly lists small- and mid-cap stocks, with trading modes similar to NYSE. Its unique advantage is providing trading in stocks, futures, and derivatives simultaneously, making it the only exchange in the US with such capabilities.
