5. In-depth Overview of the Three Major US Stock Exchanges

A key difference between US stocks and Taiwanese stocks is that Taiwanese stocks are traded on a single exchange, whereas US stocks are dispersed across multiple exchanges. Each exchange operates independently, and opening, closing, and stock prices may have slight differences. The three major US stock exchanges are:

1. New York Stock Exchange (NYSE)

The NYSE is recognized as the world’s largest stock exchange based on market capitalization, with over 3,500 listed companies. Although it primarily uses electronic trading now, floor trading still plays an important role, especially in pricing mechanisms and large institutional transactions.

2. NASDAQ

NASDAQ is characterized by fully electronic trading and was the world’s first electronic securities market. Investors trade directly via phone or internet. Most NASDAQ-listed stocks are high-tech companies, such as Microsoft, Apple, and other well-known tech firms.

3. American Stock Exchange (AMEX)

The AMEX is the third-largest trading market in the US, similar in operation to NYSE but mainly listing small- and mid-cap stocks. Notably, it is the only exchange that can trade stocks, futures, and derivatives simultaneously. After being acquired by NYSE in 2008, it was renamed NYSE American.
