2025 US Stock Market Trading Hours Complete Guide | Malaysian Investors Must-See Market Opening and Closing Schedule

Important Update: U.S. Stock Market Enters New Daylight Saving Time Period in 2025

In 2025, the United States officially begins Daylight Saving Time on March 9th, which means the regular trading hours for U.S. stocks are adjusted to 21:30 to 4:00 Beijing Time the next day. Additionally, the NYSE is advancing the NYSE Arca extension plan, and once approved, trading hours on workdays will reach 22 hours.

What does this time adjustment mean for Malaysian investors? Compared to the winter schedule opening at 22:30, the market now opens an hour earlier at 21:30, directly affecting the routines of traders in the Asia-Pacific region.

Regular Trading Hours (Eastern Time): Monday to Friday 9:30-16:00

Pre-market Trading: 4:00-9:30 (some investors participate early)

After-hours Trading: 16:00-20:00 (less active trading)

In-Depth Comparison of the Three Major U.S. Stock Exchanges

New York Stock Exchange (NYSE)

Founded in 1792, it is the world’s largest stock trading market. Although electronic trading has become dominant, floor trading remains important for large institutional transactions and price discovery. Based on total market capitalization of listed securities, NYSE remains the top globally.

NASDAQ Stock Market

As the second-largest stock exchange globally, NASDAQ was the first fully electronic stock market. Investors can trade directly via phone or internet without physical presence. It is home to many tech giants like Microsoft, Apple, and other industry leaders.

American Stock Exchange (AMEX)

Ranking third, it mainly lists small- and mid-cap stocks and is the only exchange that trades stocks, futures, and derivatives simultaneously. Its trading model is similar to NYSE but focuses on financing small and medium enterprises.
