Qu’est-ce que le hedging en trading ?

Hedging in trading is opening a second position that profits when your first position loses, with the aim of reducing or removing exposure to a specific risk. It is insurance, not a profit strategy. A hedge has a cost (premium, basis, opportunity cost) and the trader accepts that cost in exchange for a known outcome.

The mental model

Every position has three risks attached: direction, time, and event. A hedge isolates one of those risks and neutralises it while leaving the others intact. Examples:

• Long Apple stock + buy a put: directional downside hedged, upside intact, cost is the put premium.
• Long EUR/USD + short GBP/USD (correlated): partial hedge against a broad dollar-strength move.
• Long S&P 500 + short Nasdaq futures: hedges tech-driven downside while keeping value-stock upside.

The four most common hedge structures

1. Protective put. Long stock, long put. Capped downside, full upside, cost is the premium.
2. Covered call. Long stock, short call. Income from the premium, capped upside, full downside.
3. Pairs trade. Long stock A, short correlated stock B. Removes market direction, leaves relative-value exposure.
4. Cross-asset hedge. Long equities, long gold or long volatility. Removes systemic-shock risk via correlated safe-haven assets.

What does a hedge cost?

• Premium. Options cost cash up front. A 5%-out-of-the-money 30-day SPX put costs roughly 0.5-1.5% of notional in normal volatility regimes.
• Carry. Holding offsetting futures or CFDs costs financing on the long leg and earns financing on the short leg. Net carry is rarely zero.
• Basis risk. The hedge instrument is not identical to the underlying. The mismatch can move against you independently.
• Opportunity cost. Capital posted as margin on the hedge cannot work elsewhere.

When does hedging make sense?

• Concentrated exposure. A single stock that is 30%+ of liquid net worth. Selling triggers tax; hedging delays the question.
• Event risk. Earnings, FOMC, election, regulatory decision. The thesis works long-run but the path is unsafe.
• Mandatory caps. A fund’s risk policy requires a maximum drawdown. The hedge converts open-ended risk into a known floor.
• Treasury exposure. A corporate with foreign currency receivables hedges to lock in domestic-currency revenue.

What goes wrong

• Hedge slippage. The protective put is bought too far out of the money, or the pairs trade has too low a correlation. The hedge does not perform when needed.
• Premium drag. Rolling protective puts every month for a year can cost 10-15% of notional. In a flat market the hedge is the only loser.
• Hedge becomes speculation. The trader closes the original position but keeps the hedge for a directional view. Now it is a naked short, not a hedge.
• Counterparty risk. OTC hedges depend on the counterparty paying out. Use regulated venues and check ICF coverage.
