Futures and options are derivative contracts whose value is linked to an underlying asset, such as an index, share, currency, commodity or interest-rate benchmark. They can be used for hedging, exposure management and speculation. Because derivatives can create leveraged exposure, understanding the contract is essential before trading.
What is a futures contract?
A futures contract is an agreement to buy or sell an underlying asset at a specified price for settlement at a future date, subject to the contract’s terms. Exchange-traded futures are standardised. Traders generally post margin rather than paying the full notional value upfront. Positions are marked to market under the exchange and clearing framework, so losses can require additional funds.
What is an options contract?
An option gives its buyer a right, but not an obligation, under the contract terms. A call option provides the right to buy; a put option provides the right to sell. The buyer pays a premium. The option seller receives the premium but takes on an obligation if assigned or exercised, depending on the market’s settlement rules.
Understand the payoff before entering
A long futures position generally gains when the underlying rises and loses when it falls, before costs and contract adjustments. A long call benefits from a rise above its effective breakeven at expiry; a long put benefits from a fall below its effective breakeven. Option outcomes before expiry are also affected by implied volatility, time remaining, interest rates and the underlying price.
Margin is not the maximum loss
Initial margin is collateral required to open a position. It is not a cap on losses. A futures position can lose more than the margin deposited, and a short option can carry substantial or theoretically unlimited risk depending on the contract. Margin requirements may change during volatile markets. Traders must understand liquidation, margin calls and broker policies.
Key terms to know
- Lot size: the contract quantity represented by one lot.
- Expiry: the date and process for contract settlement.
- Strike: the price at which an option’s right applies.
- Premium: the price paid by an option buyer.
- Open interest: outstanding contracts that remain open.
- Implied volatility: the volatility level embedded in option prices.
- Mark-to-market: periodic valuation and settlement of gains or losses.
A practical risk checklist
Before trading, verify the exchange contract specifications, lot size, expiry, settlement method, trading hours and applicable charges. Calculate the notional exposure and stress-test the position for adverse price moves. Define the maximum acceptable loss and avoid using funds needed for essential expenses. A margin calculator can help estimate required collateral, while a trading risk calculator can support risk planning.
Common beginner mistakes
- Assuming margin equals maximum possible loss.
- Buying options without understanding time decay and volatility.
- Selling options because the premium looks attractive.
- Holding positions through expiry without knowing settlement rules.
- Ignoring transaction costs, slippage and liquidity.
- Increasing position size after a loss to recover quickly.
Frequently asked questions
Are futures riskier than investing in shares?
They can create much greater exposure relative to the cash posted, so losses can accumulate quickly.
Can an option buyer lose more than the premium?
A buyer of a plain-vanilla long option generally risks the premium paid, plus costs, if held to expiry. Strategies involving multiple legs can have different risk profiles.
Should beginners trade derivatives?
Only after understanding the contract, payoff, margin, settlement and worst-case risk. Paper trading and education should come first.
Bottom line: Learn the contract mechanics and maximum-risk scenarios before considering a derivatives trade.
