Complete Guide to U.S. Market Holidays in 2026: Trading Hours and Investment Strategies

If you are a Korean investor investing in the U.S. stock market, it is essential to accurately understand the schedule of U.S. market holidays. Especially considering the time difference with Korea, daylight saving time, and changing trading patterns around U.S. holidays, you can develop a successful investment strategy. This guide summarizes all the information investors need to know, starting with the 2026 U.S. market holiday schedule, trading hours, and the characteristics of each exchange.

Why Do You Need to Know U.S. Market Holidays?

Many investors overlook U.S. market holidays. Not knowing in advance when the U.S. stock market is closed can lead to sudden trading restrictions. Since the U.S. market operates overnight Korea time, investors must consider U.S. holidays and Korea trading hours simultaneously.

Additionally, market sentiment can change significantly before and after U.S. market holidays. Major holidays like Christmas and Thanksgiving often see trading volume drop sharply or experience frequent volatility at the market open.

All About Major U.S. Exchanges: NYSE, NASDAQ, AMEX

The U.S. stock market operates through three major exchanges. Understanding their characteristics can greatly help in selecting investment targets.

New York Stock Exchange (NYSE): The Traditional Exchange

Founded in 1792, NYSE is the world’s largest exchange. About 2,400 companies are listed, with a total market cap of approximately $23 trillion. It mainly lists traditional large-cap companies, such as Berkshire Hathaway, Johnson & Johnson, Visa, and Walmart.

NASDAQ Stock Market: The Tech Hub

Established in 1971, NASDAQ is a relatively young exchange but has grown rapidly to become the second-largest in the world. It is characterized by listings of mainly IT companies, including giants like Apple, Microsoft, and NVIDIA.

American Stock Exchange (AMEX): The Stage for Mid- and Small-Caps

One of the three major U.S. exchanges, AMEX primarily lists mid-sized and small companies. It features emerging firms and companies in specialized sectors.

U.S. Market Trading Hours: Regular vs. After-Hours Trading

All three U.S. exchanges operate during the same hours. However, when converted to Korea time, trading occurs overnight, which is important to note.

Regular Trading Hours

Eastern Time: 09:30 ~ 16:00
Korea Time: 23:30 ~ 06:00 (during daylight saving time: 22:30 ~ 05:00)

Regular U.S. market trading happens late at night to early morning Korea time, requiring traders to plan accordingly.

After-Hours Trading: Pre-market and After-market

Beyond regular hours, trading opportunities exist, but liquidity is lower and volatility higher.

Pre-market:

• Eastern Time: 04:00 ~ 09:30
• Korea Time: 18:00 ~ 23:30 (during daylight saving: 17:00 ~ 22:30)
• Features: Trading in late afternoon to night

After-market:

• Eastern Time: 16:00 ~ 20:00
• Korea Time: Next day 06:00 ~ 10:00 (during daylight saving: 05:00 ~ 09:00)

Complete U.S. Market Holiday Schedule for 2026

Knowing the days when the U.S. markets are closed helps in planning investments without surprises. Here is the full holiday schedule:

A total of 10 market holidays. Each holiday can influence market mood differently; for example, trading volume drops significantly during Christmas season, and the first trading day of the new year (Jan 2) often sees heightened volatility.

Early Market Close Dates: Don’t Miss Trading Opportunities

In addition to holidays, certain dates feature early market closures, limiting trading opportunities. Planning ahead is crucial.

On early close days, liquidity drops sharply. If planning large trades, it’s advisable to execute orders in advance.

Impact of Daylight Saving Time on Trading Hours

U.S. Eastern Time observes daylight saving from the second Sunday in March to the first Sunday in November.

During DST, all trading hours shift forward by one hour. Korea investors should adjust their schedules accordingly.

Example:

• Before DST: 23:30 Korea time = 09:30 ET
• During DST: 22:30 Korea time = 09:30 ET

Key Regulations for U.S. Stock Trading

U.S. trading rules differ from Korea’s, and understanding them helps prevent unexpected losses.

1. No Price Limitations
Unlike Korea, which has daily price limits, the U.S. market has no such restrictions. Extreme price swings are possible, especially overnight, making quick responses necessary.

2. T+2 Settlement
Settlement occurs two business days after the trade date. Funds or securities cannot be transferred immediately after trading.

3. USD Denominated Transactions
All trades are conducted in U.S. dollars, so exchange rate fluctuations should be considered.

2. Caution on Early Close Days
