A: Stock options give their owners the right to buy or sell stocks or other investments at a prearranged price in the future. But in most cases, options can only be bought or sold during regular trading hours. A vast majority of the options on U.S. stocks trade between 9:30 a.m. ET and 4 p.m ET. Most stocks, though, can be traded before or after those hours.
Unlike the stock market, which is open from 9:30 a.m. to 4 p.m eastern time on weekdays, electronic futures trading runs almost 24 hours a day, five days a week. As a result, the trading of stock index futures such as the Dow futures contracts provide overnight and early morning indicators on where the stock market is headed.
