What Does Futures Mean
A future is a standardized legal agreement to buy or sell a specific asset at a predetermined price on a set date in the future. In finance, the term refers to a derivative contract traded on an exchange, but in everyday speech it simply means something that has not yet happened.

How Futures Contracts Work
A futures contract locks in the price of an underlying asset today for delivery at a later date. The underlying asset can be a commodity like crude oil or wheat, a financial instrument like a stock index or Treasury bond, or a currency. Buyers take a long position, agreeing to purchase; sellers take a short position, agreeing to deliver. Both parties post margin, a good-faith deposit that covers potential losses as the contract's value fluctuates.
Futures vs Options vs Spot
Futures differ from options in a key way: an option gives the right but not the obligation to trade, while a futures contract creates an obligation for both sides. Compared to a spot purchase, where goods change hands immediately, futures defer the transaction and price discovery to a later month. This distinction matters for hedgers who lock in costs and speculators who bet on price direction.
Common Uses of Futures
- Hedging: A farmer sells corn futures to lock in a selling price before harvest, protecting against a price drop.
- Speculation: A trader buys S&P 500 futures to gain exposure to the stock market without purchasing every stock in the index.
- Arbitrage: A participant exploits a price gap between a futures contract and the underlying asset or between two exchanges.
Key Contract Specs to Know
| Attribute | Detail | Context |
|---|---|---|
| Expiration | Monthly or quarterly dates | Last day the contract is valid |
| Tick size | Smallest price move | Varies by asset |
| Margin | Good-faith deposit | Set by the exchange and broker |
| Settlement | Cash or physical delivery | Most financial futures settle in cash |
Risks and Considerations
Futures amplify both gains and losses because of leverage. A small price move can result in a large percentage change in the account balance. Before trading, it is important to understand margin calls, contract sizes, and the cost of rolling a position from one expiration month to the next.
