A derivative is a financial contract whose value depends on the price or performance of another asset or measure — for example a stock, index, interest rate, commodity, or currency. Investors use derivatives like insurance or leveraged bets to hedge risk, speculate, or gain exposure without owning the underlying asset; they can protect portfolios but also amplify losses and introduce counterparty and market risk.
