I recently researched the opening hours of the U.S. stock market and found that trading U.S. stocks as someone in Taiwan is actually quite complicated—mainly because of the time difference. The United States is currently on winter time, so the regular trading session is from 9:30 AM to 4:00 PM Eastern Time, which translates to 10:30 PM to 5:00 AM the next day in Taiwan. If you’re a night owl, that’s fine, but for people who wake up early, it can be a bit difficult.

Unlike the Taiwan stock market, which has only one exchange, the U.S. mainly has three: the New York Stock Exchange, NASDAQ, and the American Securities Exchange. NASDAQ is more well-known because many technology stocks are listed there, such as Microsoft and Apple, along with other major companies. However, most of the time, the opening and closing times of these exchanges are synchronized, so you don’t need to worry too much.

Another thing to note is that the U.S. switches between daylight saving time and standard time. Each year, on the second Sunday in March, the clocks are set forward by one hour, and on the first Sunday in November, they’re set back. This is very important for investors in Taiwan, because the time difference shifts by one hour. Also, the U.S. has quite a number of holidays this year when the market is closed, such as Independence Day, Thanksgiving, and Christmas. Before investing, make sure to check in advance so you don’t end up trying to trade when the market isn’t open.

In fact, as long as you get the stock market opening times and holiday schedule down, trading U.S. stocks won’t lead you into trouble. It’s recommended that you mark them on a calendar so you don’t miss any trading opportunities.
