Since 1985, the regular trading hours for major exchanges in the United States, such as the New York Stock Exchange and the Nasdaq Stock Market, have been from 9:30 a.m. to 4:00 p.m. Eastern Time (ET). Pre-market trading occurs from 4:00 a.m. to 9:30 a.m. ET, although the majority of the volume and liquidity come to the pre-market at 8:00AM ET. After-hours trading on a day with a normal session occurs from 4:00 p.m. to 8:00 p.m. ET.
The major U.S. stock exchanges are open for only 6 1/2 hours a day, five days a week. But plenty of investors seem willing to stare at their computer screens and scream with joy or rage 24/7. For them, there's after-hours trading. Trading that takes place after hours can definitely affect the opening price of a stock, but there's no guarantee it will.
