4. Practical Tips for Mastering U.S. Stock Market Hours

For investors interested in trading U.S. stocks, accurately understanding the trading hours is crucial. Due to the complexity of time zones and DST adjustments, it is recommended that investors:

1. Mark Time Zone Conversion Points: Adjust expectations around trading hours during the DST transition dates in March and November.
2. Plan Ahead for Holidays: Review holdings before major public holidays to avoid risks of inability to close positions during holidays.
3. Utilize Pre-market and After-hours Trading: For Taiwanese investors unable to trade during regular hours, pre-market and after-hours sessions offer additional opportunities.
4. Follow Real-time Market Updates: Since there is a significant time difference between U.S. and Taiwan markets, using professional trading platforms for real-time quotes and updates is advised.

Mastering these U.S. stock hours will help you plan your trading more effectively and avoid opportunity costs caused by time discrepancies.
