You can still place stock orders when the markets are closed.

Traditionally, the markets are open from 9:30 AM-4 PM US Eastern time (ET) during regular business days (Monday-Friday, except holidays). But with extended-hours trading and the Robinhood 24 Hour Market, you can execute trades from 8 PM ET Sunday until 8 PM ET Friday, with some restrictions. Orders placed outside these hours will be queued to process when the market opens on the next trading day.

Check out Extended-hours trading and Robinhood 24 Hour Market for more details about how you can trade during regular, extended, and overnight market hours.

• Earnings announcements: The companies you own shares of may announce quarterly earnings after the market closes. Depending on the outcome, the stock’s price can move much more than it would during the regular-hours session. With extended-hours trading, you can act on these potential opportunities as they happen.
• Activity in foreign markets: Foreign markets, such as Asian or European markets can influence prices on US markets. Activity on these markets happens outside regular US market hours, and extended-hours trading allows you to act on some of these potential opportunities around these events.

• Risk of higher volatility: Volatility refers to the changes in price that securities undergo when trading. Generally, the higher the volatility of a security, the greater its price swings. There may be greater volatility during extended hours than during regular market hours.
• Risk of news announcements: Normally, issuers of securities make news announcements that may affect the price of their securities after regular market hours. Similarly, important financial information is frequently announced outside of regular market hours. In extended-hours trading, these announcements may occur during trading, and if combined with lower liquidity and higher volatility, may cause an exaggerated and unsustainable effect on the price of a security.
