2025-2026 US Stock Market Trading Calendar Complete Guide | Essential Opening and Closing Times for Taiwanese Investors

I. Essential US Stock Market Opening Times for Taiwanese Investors

Current Status: The United States entered Standard Time at 2:00 AM on November 2, 2025. The regular trading hours are from 22:30 to 5:00 the next day Taiwan time.

This information is crucial for Taiwanese investors—because US stock trading hours directly impact when you can place orders. Unlike other Asian markets, the opening times of US stocks change due to daylight saving time and standard time transitions.

Major US Stock Trading Sessions (Eastern Time)

The US has three main stock exchanges—NYSE, NASDAQ, and AMEX—they open simultaneously, divided into three trading sessions:

Transition Times Between Daylight Saving and Standard Time

The US adjusts clocks twice a year:

• Daylight Saving Time: Starts at 2:00 AM on the second Sunday in March, ends at 2:00 AM on the first Sunday in November
• Standard Time: Starts at 2:00 AM on the first Sunday in November, ends at 2:00 AM on the second Sunday in March the following year

During these transitions, clocks are moved forward or back by 1 hour, which means the US stock trading times you see in Taiwan will also shift accordingly. Many investors overlook this and miss key trading windows.

II. US Stock Market Holidays 2025-2026 Overview

Unlike regular stock trading, US markets are completely closed on major holidays. Investors must plan ahead to avoid trading on market holidays.

Important Reminder: Besides fully closed days, pay attention to dates when markets close 3 hours early. Trading still occurs on these days, but the early close may affect your exit strategies.

III. Basic US Stock Trading Rules and Knowledge

US stock trading uses a T+3 settlement system, meaning funds are settled three business days after the trade. Transaction fees are approximately 1% for manual trades and 0.5%-1% for electronic trades.

The minimum trading unit is 1 share, which is quite different from Taiwan’s thousand-share lot. US stocks are traded in USD (US Dollars).

Overview of the Three Major Exchanges:

NYSE (New York Stock Exchange) is the world’s largest stock exchange by market capitalization, listing over 3,500 stocks. Although modern trading is electronic, floor trading still plays an important role in pricing and large institutional transactions.

NASDAQ is the world’s first electronic securities market and the first fully electronic exchange. Investors trade directly via phone or internet. It hosts many high-tech giants like Microsoft, Apple, and others.

AMEX (American Stock Exchange) ranks third among US stock markets, mainly featuring small- and mid-cap stocks. Acquired by NYSE in 2008, it is now called NYSE American. It is the only US exchange that can trade stocks, futures, and derivatives simultaneously.

V. Investment Tips Summary

When trading US stocks, the two most critical points for Taiwanese investors are accurately mastering the Taiwan time conversion table and planning ahead for US market holidays.

Additionally, review the US market holiday schedule before each quarter to avoid missing trading opportunities or incurring unnecessary losses.
