The core trading hours for the U.S. stock market are from 9:30 AM to 4:00 PM ET. During this time, investors actively buy and sell stocks through various exchanges, such as the New York Stock Exchange (NYSE) and the Nasdaq.

2. Pre-Market and After-Hours Trading:

a. Pre-Market Trading: Pre-market trading, as the name suggests, takes place before the official market opening. This session starts at 4:00 AM ET and continues until the market opens at 9:30 AM ET. Pre-market trading allows investors to react to significant overnight news or corporate announcements, potentially impacting stock prices. It is essential to note that pre-market trading volume tends to be lower compared to regular trading hours, and price movements can be more volatile.

b. After-Hours Trading: After-hours trading occurs after the regular market hours, between 4:00 PM and 8:00 PM ET. This session also offers opportunities for investors to trade stocks outside of the standard trading hours. As with pre-market trading, after-hours trading carries higher risks due to lower liquidity and potentially wider bid-ask spreads.
