The Three Major U.S. Stock Exchanges and Trading Rules

The U.S. stock market consists of several independently operated securities exchanges, mainly including:

New York Stock Exchange (NYSE) — The world’s largest stock exchange, listing over 3,500 stocks with the highest total market value globally. Trading is primarily electronic, but floor trading still plays an important role in large institutional orders.

NASDAQ Stock Market (NASDAQ) — The world’s first fully electronic stock exchange, where investors mainly trade via phone or online directly. Major tech companies like Microsoft, Apple, and others are listed here.

American Stock Exchange (AMEX) — The third-largest trading market in the U.S., now renamed NYSE American. It specializes in small- and mid-cap stocks and is the only exchange that can trade stocks, futures, and derivatives simultaneously.

Although each exchange operates independently, most of the time, all exchanges are synchronized in their opening hours.
