What makes US stock trading hours so complicated?
When investing in US stocks, the first challenge to overcome is understanding the exact trading hours. The trading hours for US stocks are much more complex than we might think.

Misunderstanding the trading hours can lead to missed opportunities or unexpected losses. In this article, I will thoroughly explain the US stock trading hours, including the characteristics of each exchange, holiday closures in 2025, and the time zone 기준 for Korea.
