Derivative transactions are contracts whose value depends on the price or performance of something else—like stocks, bonds, currencies, interest rates or commodities. Think of them as insurance or bets about a future price: investors use them to protect against losses, lock in prices, or try to amplify returns, but they can also magnify losses, create cash demands and expose a firm to the risk that the other party won’t meet its obligation, so they can materially affect a company’s financial stability and volatility.
