Futures are standardized contracts to buy or sell an asset at a set price on a set future date. They trade on regulated exchanges and are used to speculate on price or to hedge existing exposure. They are powerful, highly leveraged, and unforgiving of sloppy risk management. This lesson builds the vocabulary; it is not a trading recommendation.
What a futures contract is
- Contract — an agreement to exchange an asset at an agreed price on a set date, in a fixed quantity defined by the exchange.
- Underlying — what the contract tracks: an index (E-mini S&P 500), a commodity (crude oil, gold), a currency, or a rate.
- Expiration — futures settle or roll on set dates; most active traders roll to the next contract rather than take delivery.
One contract controls a large, fixed amount of the underlying — so small price moves translate into large dollar swings.
Leverage and margin
Futures are traded on margin — a good-faith deposit, not the full contract value:
- Initial margin — the deposit required to open a position.
- Maintenance margin — the minimum equity to keep it open; fall below and you get a margin call.
- Mark-to-market — gains and losses settle to your account daily, not just when you exit.
Why people use them
| Goal | Example use |
|---|---|
| Speculation | Take a leveraged view on an index or commodity |
| Hedging | Offset risk in a portfolio or a physical business |
| Access | Trade nearly 24 hours and go long or short with equal ease |
The risk reality
Because a small deposit controls a large position, a modest move against you can wipe out your margin and then some — losses can exceed your initial deposit. Futures are among the fastest ways to lose money without strict, pre-defined risk. Never trade size you cannot afford to lose, and never hold a leveraged position you have not planned an exit for.
A sane on-ramp
- Learn by paper trading a single contract first.
- Prefer micro contracts (e.g. Micro E-mini) to keep dollar risk small while you learn.
- Size every position with the same risk rules as any trade, and always know your stop before you enter.
A diversified, long-term portfolio requires zero futures. Treat them as an advanced, optional tool for hedging or active trading — not a shortcut to returns.
This lesson is for education. Trading futures involves substantial risk of loss and is not suitable for every investor. Nothing here is a recommendation to buy or sell any instrument. See our full risk disclaimer.
