Financial contracts whose value is tied to the price or performance of another asset, such as a stock, bond, commodity, index, or currency; examples include options, futures and swaps. They matter to investors because they let you protect against price swings, bet on future moves or gain larger exposure with less upfront cash—like using a lever or insurance policy on an investment—so they can amplify gains and losses and help manage portfolio risk.
