• Standard Time: Starts at 2:00 AM on the first Sunday in November, clocks move back 1 hour
• Special Note: Different states may have different regulations, but New York Stock Exchange follows federal time

4. Overview of the Three Major U.S. Stock Exchanges

The key difference between U.S. stocks and Taiwan stocks is that U.S. stocks are not concentrated in a single exchange but are traded across three major exchanges. Each operates independently, so opening prices, closing prices, and some stock quotes may vary slightly.

New York Stock Exchange (NYSE)

The NYSE is the largest stock exchange in the world by total market capitalization of listed companies, with over 3,500 listed stocks. Although modern trading is mainly electronic, floor trading still plays an important role, especially in setting large institutional trade prices.

NASDAQ Stock Market

NASDAQ is a fully electronic exchange, without a physical trading floor, and was the first electronic securities market globally. Investors trade directly via phone or internet. Many high-tech companies are listed on NASDAQ, such as Microsoft, Apple, and other tech giants.

American Stock Exchange (AMEX)

AMEX is the third-largest trading market in the U.S., with trading methods similar to NYSE. It mainly lists small- and mid-cap stocks and is the only exchange that can trade stocks, futures, and derivatives simultaneously. After being acquired by NYSE in 2008, it is now called NYSE American.

5. Major Global Stock Market Trading Hours

Besides U.S. stocks, Taiwanese investors can also pay attention to other countries’ markets. Here are the trading hours of major global stock exchanges:
