A derivative is a financial contract whose value is tied to the price of something else, called the underlying asset. That underlying asset might be a stock, a bond, a commodity like gold or oil, a currency, or even a broad market index like the S&P 500. You never buy or sell the asset itself when you trade a derivative. Instead, you enter a contract that rises or falls in value based on what happens to the asset’s price. Derivatives serve two main purposes: helping businesses protect themselves against price swings, and giving traders a way to profit from those same price movements.
How Derivatives Get Their Value
The word “derivative” comes from “derived.” The contract has no independent worth. Its value is entirely a function of what the underlying asset does. If you hold a derivative contract tied to gold, and gold’s price climbs 10%, your contract’s value shifts accordingly, either in your favor or against you depending on which side of the contract you’re on.
This relationship is what makes derivatives powerful and, at times, risky. A relatively small move in the underlying asset can translate into a much larger gain or loss on the derivative, because most derivative contracts let you control a large amount of the asset while putting up only a fraction of its total value. This effect is called leverage. In futures markets, for example, margin requirements might be only 5% to 10% of the contract’s total value, meaning a small price swing gets amplified significantly.
The Four Main Types
Futures
A futures contract is an agreement to buy or sell an asset at a set price on a specific future date. These contracts trade on regulated exchanges with standardized terms. Every day, your account is “marked to market,” meaning gains or losses are added to or subtracted from your cash balance at the end of each trading session. If the price moves against you, your balance drops in real time rather than waiting until the contract expires. You’re required to keep a minimum balance (called margin) in your trading account to hold the position open.
Options
An option gives you the right, but not the obligation, to buy or sell an asset at a predetermined price (called the strike price) by a certain date. A “call” option is the right to buy. A “put” option is the right to sell. Because you have the right but aren’t forced to act, the most you can lose as a buyer is the price you paid for the option, known as the premium. If the market moves in your favor, you can exercise the option. If it doesn’t, you simply let it expire. Options come in two styles: American options, which you can exercise at any point before expiration, and European options, which you can only exercise on the expiration date itself.
Forwards
A forward contract works similarly to a futures contract. Two parties agree today on a price for a transaction that will happen on a future date. The key difference is that forwards are private agreements, not traded on an exchange. They can be customized to any amount, asset, or settlement date the two parties agree on. At maturity, the contract’s value equals the difference between the agreed-upon price and the asset’s actual market price. If you agreed to buy at $100 and the asset is worth $110 at settlement, the contract is worth $10 to you.
Swaps
A swap is an agreement between two parties to exchange a series of cash flows over time. The most common type is an interest rate swap, where one party pays a fixed interest rate on a set amount of money (called the notional principal) while the other pays a variable rate on the same amount. The principal itself never changes hands. Only the interest payments are exchanged. Companies use interest rate swaps to convert variable-rate debt into fixed-rate debt, or vice versa, depending on their outlook on rates. Currency swaps work similarly but involve exchanging payments in different currencies.
Hedging: Reducing Business Risk
The original purpose of derivatives is hedging, which means taking a position that offsets potential losses in something you already own or need. A jewelry manufacturer with a large order due in six months, for instance, faces a real problem if gold prices spike before the order is filled. By buying a six-month gold futures contract, the company locks in today’s price. If gold rises 10%, the higher cost of raw materials is offset by gains on the futures contract. The company sacrifices the chance to benefit from falling gold prices, but it eliminates the uncertainty, and for most businesses, predictable costs matter more than speculative upside.
Airlines routinely hedge fuel costs the same way. Farmers use futures to lock in crop prices before harvest. Multinational corporations use currency swaps to manage exchange rate exposure on overseas revenue. In each case, the derivative acts as insurance against an unfavorable price move.
Speculation: Profiting From Price Moves
Speculators use derivatives not to reduce risk but to take it on deliberately, betting on which direction an asset’s price will move. Because derivatives offer leverage, a speculator can gain exposure to a large position with a relatively small amount of capital. If a trader believes oil prices will rise, buying oil futures lets them profit from that move without purchasing and storing physical barrels of oil. The leverage works both ways, though. A wrong bet can produce losses that exceed the original amount invested, especially with futures and forwards where there is no built-in cap on how much you can lose.
Speculation serves a practical function in the broader market. Speculators provide liquidity, making it easier for hedgers to find someone willing to take the other side of their trades. Without speculators, hedging would be more expensive and less efficient.
Where Derivatives Trade
Derivatives trade in two main venues, and the distinction matters for risk.
Exchange-traded derivatives, like standard futures and options contracts, are bought and sold on regulated exchanges. These contracts are standardized in their terms, sizes, and expiration dates. A clearinghouse sits between the buyer and seller on every transaction, acting as the counterparty to both sides. This setup virtually eliminates the risk that the other party defaults on the deal. The transparency and regulation of exchanges make them accessible to individual investors, and the standardization keeps them liquid, meaning you can usually enter or exit a position quickly at a fair price.
Over-the-counter (OTC) derivatives, like forwards and most swaps, are negotiated privately between two parties, often large institutions. OTC contracts can be tailored to exact specifications, giving institutional investors the precise risk exposure they want. The tradeoff is higher complexity and counterparty risk, since there’s no clearinghouse guaranteeing the trade. If the other party can’t pay, you may not collect what you’re owed. OTC markets are where the largest and most complex derivative transactions happen, but they’re generally not suitable for individual investors.
How Individual Investors Encounter Derivatives
If you have a brokerage account, the derivatives you’re most likely to encounter are stock options and futures contracts on major indexes or commodities. Buying a call option on a stock you already own, for instance, is a straightforward strategy that many retail investors use. Selling options against shares you hold (called a covered call) is another common approach that generates extra income from a stock position.
Most brokerages require you to apply for options trading and will assign you a level of access based on your experience and financial situation. Simpler strategies like buying calls and puts or writing covered calls are typically approved first, while more complex multi-leg strategies require higher approval levels. Futures accounts are usually separate from standard brokerage accounts and come with their own margin requirements.
Derivatives can amplify both gains and losses, so understanding the mechanics of any contract before trading it is essential. The leverage that makes them capital-efficient is the same feature that can turn a small market move into a significant hit to your account balance.
