An options contract gives an investor the right, but not the obligation, to buy (or sell) shares at a specific price at any time, as long as the contract is in effect. By contrast, a futures contract requires a buyer to purchase shares—and a seller to sell them—on a specific future date, unless the holder’s position is closed before the expiration date.
Options and futures are both financial products investors can use to make money or to hedge current investments. Both an option and a future allow an investor to buy an investment at a specific price by a specific date. But the markets for these two products are very different in how they work and how risky they are to the investor.
