A Must-Read for Beijing Investors: Time Difference Table

Since the U.S. observes Daylight Saving Time and Standard Time, while Beijing remains fixed year-round, investors need to adjust seasonally. Daylight Saving Time in the U.S. begins at 2:00 AM on the second Sunday in March and ends at 2:00 AM on the first Sunday in November; Standard Time is the opposite.

What Are the Differences Among the Three Major U.S. Stock Exchanges?

New York Stock Exchange (NYSE)

The “big brother” of U.S. stocks. Founded in 1792 on Wall Street, it is currently the largest stock exchange in the world by total market capitalization of listed securities. While mainly electronic, floor trading remains important for pricing and large institutional transactions.

NASDAQ

The second-largest exchange globally and the world’s first fully electronic securities market. Investors trade directly via phone or internet without restrictions of a trading floor. It hosts giants like Microsoft and Apple, with the highest concentration of high-tech companies.

American Stock Exchange (AMEX)

The “old third” of U.S. stocks, with trading modes similar to NYSE. Its特色 is mainly trading small- and mid-cap stocks, and it is the only exchange that can trade stocks, futures, and derivatives simultaneously.
