Introduction

The regular U.S. stock market is open from 9:30 a.m. to 4 p.m. Eastern Time. But trading does not completely stop when the closing bell rings. Investors can also trade during extended hours, including after-hours sessions.

What Is After-Hours Trading?

After-hours trading typically takes place from 4 p.m. to 8 p.m. Eastern Time. There is also pre-market trading in the early morning before the regular session. These trades happen through electronic networks rather than the main exchange floor.

Why Prices Move After Hours

Many companies release earnings reports right after the market closes. Stock prices can jump or fall sharply in after-hours trading as investors react to the news. Major economic or political events overnight can also move prices before the next day's open.

Risks to Know

After-hours trading usually has fewer buyers and sellers, which means lower liquidity. Prices can be more volatile, and the gap between buying and selling prices can be wider. Many brokers only allow limit orders during extended hours to protect investors.

Conclusion

After-hours trading shows that markets react to news around the clock. For most long-term investors, though, the regular trading day is more than enough!
