Introduction: Why Accurate Trading Times Matter

If you are investing in U.S. stocks, knowing the precise trading timing is not optional but essential. Especially in the real-time U.S. stock market, time differences with Korea, daylight saving time transitions, and unexpected holiday schedules can significantly impact your trading plans. To avoid missing trading opportunities or incurring unexpected losses due to incorrect time information, the systematic information provided in this article will be helpful.

Understanding the Characteristics of the 3 Major U.S. Stock Exchanges

The main exchanges driving the real-time U.S. stock market are the New York Stock Exchange(NYSE), NASDAQ(NASDAQ), and American Stock Exchange(AMEX). Each exchange has its own unique features and listed company portfolios.

The Status of the New York Stock Exchange(NYSE)

Founded in 1792, NYSE remains the world’s largest stock exchange. About 2,400 companies are listed, with a total market capitalization of approximately $23 trillion. It mainly trades large-cap global companies like Berkshire Hathaway, Johnson & Johnson, Visa, and Walmart. To grasp the trends of traditional industries in the real-time U.S. stock market, following NYSE’s movements is essential.

The Tech-Centric Ecosystem of NASDAQ(NASDAQ)

Established in 1971, NASDAQ is the second-largest exchange globally, primarily listing IT and technology companies. Companies leading the era such as Apple, Microsoft, and NVIDIA are listed on NASDAQ. Growth investors should monitor NASDAQ’s real-time U.S. stock market data.

The Small and Medium Enterprise Platform of the American Stock Exchange(AMEX)

AMEX hosts relatively mid-sized and small companies compared to NYSE and NASDAQ. It offers opportunities for investors interested in emerging companies or value stocks.

Trading Time System: Regular Trading and After-Hours Trading

The real-time U.S. stock market is divided into regular trading hours and after-hours trading(pre-market, after-market). Accurately understanding these trading sessions is the first step in developing a trading strategy.

Regular Trading Hours and Correspondence with Korean Time

All three exchanges conduct regular trading from 9:30 a.m. to 4:00 p.m. Eastern Time. In Korean time, this is from 11:30 p.m. to 6:00 a.m. the next day. However, during daylight saving time, from the second Sunday in March at 2 a.m. to the first Sunday in November at 2 a.m., the clocks are moved forward by 1 hour, so trading occurs from 10:30 p.m. to 5:00 a.m. Korean time.

Utilizing Pre-Market and After-Market Sessions

In addition to regular hours, after-hours trading is available in the real-time U.S. stock market. Pre-market(from 4 a.m. to 9:30 a.m. Eastern Time, which is 6 p.m. to 11:30 p.m. Korean time), allows proactive trading before major news releases. After-market(from 4 p.m. to 8 p.m. Eastern Time, which is 6 a.m. to 10 a.m. Korean time), enables trading based on post-market results. Since liquidity is lower outside regular hours, strategic judgment is necessary.

Key Trading Regulations and Differences from the Korean Market

Currency, Units, and Settlement System

All trades are conducted in U.S. dollars(USD), with a minimum trading unit of 1 share. Settlement is completed 2 business days after the trading day. Fees vary depending on the brokerage or intermediary.

Implications of No Price Limit

The biggest difference from the Korean stock market is the absence of price limit restrictions. In the U.S. stock market, prices can surge or plummet by over 30% or 50% in a single day. Since trading occurs at night Korean time, immediate response to sharp fluctuations can be challenging. It is crucial to establish stop-loss orders and risk management strategies considering this.

Major Holidays and Early Close Schedule in 2025

The real-time U.S. stock market closes on U.S. public holidays and commemorative days. There are 12 full holiday closures annually, with some days closing early.

Full Holiday Closures in 2025
