2025 US Stock Market Hours Overview: NYSE and NASDAQ Opening and Closing Times and Holidays at a Glance

US Stock Market Hours: Knowing Them Right from the Start Is Half the Success

To invest in US stocks, you need to know the trading hours precisely. Especially since there is a 13-14 hour time difference with Korea, and daylight saving time is also applied, it can be complicated. This guide clearly summarizes the regular trading hours and pre-market and after-hours times for NYSE, NASDAQ, and AMEX. It also includes information on holiday closures in 2025 and a comparison of major global stock exchanges, so please refer to it.

The 3 Major US Stock Exchanges: How Do They Differ?

The US stock market consists of three major exchanges. Understanding the characteristics of each exchange can help you develop your investment strategy.

NYSE (New York Stock Exchange)

Founded in 1792, it is the world’s largest stock exchange. It is overwhelmingly number one by market capitalization, holding about $23 trillion in listed companies. Over 2,400 large-cap and traditional industrial companies(including Berkshire Hathaway, Johnson & Johnson, Walmart)are listed, making for stable trading.

NASDAQ (NASDAQ Stock Market)

Founded in 1971, it started as an over-the-counter market and has grown into the second-largest exchange in the world. It mainly lists IT and high-tech companies, allowing trading of tech giants like Apple, Microsoft, and NVIDIA.

AMEX (American Stock Exchange)

This exchange mainly lists mid- and small-cap companies, and investors looking for mid-sized stocks tend to use it rather than large caps.

US Stock Trading Hours: From Regular Trading to After-Hours

The trading hours are the same across all three exchanges. However, when converted to Korean time, the date changes, and during daylight saving time(from the second Sunday in March to the first Sunday in November), the hours are moved forward by one hour.

Trading Currency: US Dollar(USD)
Trading Unit: 1 share
Price Limit: None (Different from Korea)
Settlement Date: 2 business days

###Features of US Stock Trading Hours

The most notable point is that there are no price limits. Korea restricts daily volatility, but the US does not. Also, since trading occurs at night Korea time, rapid fluctuations can be difficult to respond to. Be sure to consider this when planning your trades.

To trade US stocks effectively:

3. Check holidays in advance: Make sure your trading plans do not coincide with market holidays.
4. Be cautious of no price limits: Prepare for rapid declines by setting stop-loss orders in advance.
