TL;DRUsing futures contracts to reduce or offset risk in an existing position or business exposure. Hedgers are a primary reason futures markets exist.
Hedging uses a futures position to reduce risk in an existing exposure. A hedger isn't trying to profit from price movements. They're trying to protect against them.
The classic example: a corn farmer sells futures in spring to lock in a harvest price. If corn drops over summer, futures profits offset the lower crop revenue.
Commodity producers (farmers, miners, oil producers) sell futures to hedge against falling prices. Consumers (airlines, food manufacturers) buy futures to hedge against rising prices.
Portfolio managers sell index futures to hedge equity portfolios. Multinational corporations use currency futures to hedge exchange rate risk.
Most retail traders are speculators. But understanding hedging explains why futures markets exist and have such high liquidity.
A retail investor with a large stock portfolio might sell ES futures during uncertain periods without selling their stocks. This provides short-term protection while maintaining long-term positions.
A hedge doesn't eliminate risk. It converts price risk to basis risk (the risk that the hedge doesn't perfectly track the underlying exposure).
Airline hedging fuel
An airline needs 10 million gallons of fuel next quarter. Current price: $2.50/gallon.
They buy crude oil futures as a proxy. If oil rises 10%, higher fuel costs are partially offset by futures profits. The net result is a more predictable budget.
Portfolio hedge
You hold $500,000 in stocks and want protection against a 10% decline.
Short 2 ES contracts (~$520K notional). If the market drops 10%, your portfolio loses ~$50K but the short ES gains ~$52K. Imperfect if your stocks don't track the S&P exactly.
Over-hedging (more notional than your actual exposure)
Hedging $500K of stocks with $1M of futures turns a hedge into a speculative short.
Assuming a hedge is perfect
Basis risk means your hedge won't match perfectly. A wheat farmer still has quality and timing differences.
Forgetting to remove the hedge when the risk passes
Holding a hedge longer than necessary means paying opportunity cost if the market rises.
