U.S. Stock Market Opening Hours Winter Schedule Complete Guide (2025-2026)

Key Updates: The United States has entered the winter daylight saving time period. Regular trading hours are from 22:30 to 05:00 Taiwan local time.

1. Grasping the US Stock Market Trading Rhythm: Detailed Rules for Each Session

The US stock market consists of multiple independently operated securities exchanges, with the New York Stock Exchange, NASDAQ, and American Stock Exchange being the three major markets. Although each exchange operates independently, opening and closing times are synchronized, so investors do not need to worry about time discrepancies.

Trading in the US stock market is divided into three sessions, based on Eastern Time (ET):

US stocks are priced in USD, with a minimum trading unit of 1 share. Settlement cycle is T+3. Transaction fees vary by trading method: manual trades are about 1%, electronic trades are 0.5%-1%.

2. Quick Reference Table for Taiwanese Investors’ Trading Hours During Winter Time

Key understanding: Due to the US implementing daylight saving time changes between winter and summer, and Asia not observing this system, Taiwanese investors must adjust their operation times accordingly. US winter daylight saving time begins at 2:00 AM on the first Sunday in November and ends at 2:00 AM on the second Sunday in March; summer time is the opposite. When winter time begins, Eastern Time shifts back by 1 hour; when summer time begins, it shifts forward by 1 hour.

4. Overview of the Three Major US Stock Exchanges

Understanding the characteristics of each exchange helps investors better select trading targets.

New York Stock Exchange (NYSE): Based on total market capitalization of listed stocks, NYSE remains the world’s largest stock exchange, with over 3,500 listed companies. Although electronic trading has become mainstream, floor trading still plays a key role in pricing and large institutional transactions.

NASDAQ: As the world’s first electronic stock exchange, NASDAQ operates entirely electronically, with investors placing orders via phone or internet directly. It mainly lists high-tech companies, including giants like Microsoft and Apple.

American Stock Exchange (AMEX/NYSE American): The third-largest US trading market, focusing on small- and mid-cap stocks. It is the only exchange that can trade stocks, futures, and derivatives simultaneously. Acquired by NYSE in 2008, it is now called NYSE American.

5. Winter Daylight Saving Trading Planning Tips

With the arrival of winter daylight saving time, Taiwanese investors should pay attention to the following:

• Regular trading hours start earlier at 22:30 Taiwan time, allowing office workers to participate in pre-market planning after work or engage in main trading sessions at night. Night traders will find no major change in their routines.

• Shortened trading hours (by 3 hours) on days like Independence Eve and Christmas Eve require pre-planning to adjust positions and avoid forced carryovers into the next day.

• The transition between winter and summer time occurs on specific Sunday mornings. Investors should confirm the latest trading hours a week before the change to prevent operational errors caused by time confusion.
