2025-2026 US Stock Market Trading Schedule Full Analysis: Market Holidays, Opening Hours, and Taiwan Correspondence Table

US Stock Exchange Operation Mechanisms and Market Structure

The US stock market consists of multiple independently operated securities exchanges, primarily including the New York Stock Exchange (NYSE), NASDAQ, and the American Stock Exchange (AMEX). Although each exchange operates independently, in most cases, their trading hours are synchronized, and price differences are usually minimal.

New York Stock Exchange - NYSE by total market capitalization of listed securities, is the world's largest stock exchange, with over 3,500 listed stocks. Its trading methods are mainly electronic, but floor trading still plays an important role in setting prices and handling large institutional trades.

NASDAQ is the world's first fully electronic stock trading market, where investors trade directly via phone or internet. Most listed stocks are high-tech companies, such as Microsoft, Apple, and other tech giants.

American Stock Exchange - AMEX (now called NYSE American) is the third-largest trading market in the US, mainly focusing on small and mid-cap stocks, with the unique advantage of trading stocks, futures, and derivatives markets simultaneously.

US Stock Regular Trading Hours and Rules

US stock trading is divided into three sessions, all based on Eastern Time (ET):

• Pre-market trading hours: Monday to Friday, 4:00-9:30
• Regular trading hours: Monday to Friday, 9:30-16:00
• After-hours trading: Monday to Friday, 16:00-20:00

US stocks are priced in USD, with a trading unit of 1 share. The settlement cycle is T+3, with transaction fees typically around 1% for manual trades or 0.5%-1% for electronic trades.

Important for Taiwanese Investors: Time Difference Adjustment and Trading Hours Correspondence

Due to daylight saving time (DST) and standard time in the US, while Asia maintains a fixed time year-round, Taiwanese investors need to pay special attention to time difference changes.

US Daylight Saving Time: Starts at 2:00 AM on the second Sunday in March and ends at 2:00 AM on the first Sunday in November, moving clocks forward by 1 hour.

US Standard Time: Starts at 2:00 AM on the first Sunday in November and ends at 2:00 AM on the second Sunday in March, moving clocks back by 1 hour.

Currently, it is in Standard Time, so the regular US stock trading hours correspond to 22:30 to 5:00 the next day in Taiwan local time. The full correspondence is as follows:
