Regular U.S. stock market trading hours are from 9:30 a.m. EST to 4:30 p.m. EST, according to Learning Markets. Many investors use pre-market trading to gain a leg up on investors who normally trade during regular hours. Investors also use pre-market trading to react early to financial news announcements that occur outside of regular market hours.

Pre-market and after-hours trading come with specific risks outlined by the Securities and Exchange Commission, notes Learning Markets. Since pre-market hours have less trading activity than regular hours, securities prices can fluctuate more than regular hours. As there is less trading volume for some stocks in pre-market hours, it may be difficult to execute buy and sell orders due to the lack of liquidity. Another risk factor is the inability to see quotes during pre-market hours. Some brokerage houses only allow traders to view quotes from one trading system during pre-market hours.
