4. Overview of the Three Major US Stock Exchanges

The US stock market’s unique feature is its diversified exchange structure, unlike Taiwan’s concentrated Taiwan Stock Exchange. The US has three major independent exchanges. Although their opening and closing times are coordinated, due to differences in trading mechanisms and market composition, the closing prices across exchanges may have slight variations.

New York Stock Exchange (NYSE)

The NYSE ranks first globally in terms of the size of listed companies, with over 3,500 listed stocks. Its influence far exceeds other exchanges based on total market capitalization. While modern trading is largely electronic, floor trading still plays an important role in price setting and large institutional order processing.

NASDAQ

NASDAQ was the world’s first fully electronic securities market, where investors trade via phone or internet without relying on physical trading floors. It hosts many high-tech giants like Microsoft and Apple, making the NASDAQ index a key indicator of the tech industry’s health.

American Stock Exchange (AMEX)

The AMEX is the third-largest US trading market, with trading modes similar to NYSE but focusing on small- and mid-cap stocks. Its unique advantage is being the only US exchange that offers stocks, futures, and derivatives trading simultaneously. After 2008, the AMEX was acquired by NYSE and is now called NYSE American.
