Hedging means taking a position that partially or fully offsets the risk of an existing position. The purpose is not to generate profit from the hedge itself, but to reduce or eliminate the impact of adverse price moves on the primary position. Like insurance, a hedge costs money (the premium or the opportunity cost of the offsetting trade) and pays off only if the hedged event occurs.
Common Hedging Methods
Offsetting positions in correlated assets: If you're long a large position in EUR/USD, opening a smaller short in GBP/USD hedges some of the directional USD exposure (both pairs move with USD strength and weakness). The pairs aren't perfectly correlated, so it's a partial hedge.
Options hedges: Buying a put option on a stock you own provides downside protection. If the stock falls sharply, the put gains value, offsetting some of the loss. The cost is the premium paid for the put, which is lost if the stock doesn't fall. This is the cleanest and most common hedging structure for equity portfolios.
Inverse ETFs and futures: Some ETFs are designed to move inversely to an index — an S&P 500 inverse ETF gains when the index falls. These can be used to hedge a long equity portfolio without using options.
The Cost of Hedging
No hedge is free. Options hedges cost the premium. Correlated asset hedges tie up capital and generate their own risk (imperfect correlation means the hedge may not perform as expected). Futures hedges require margin and have roll costs.
The question is always: is the cost of the hedge worth the protection? For a short-term high-conviction trade you want to hold through a potentially volatile event, a cheap out-of-the-money put can be worthwhile. For long-term investors with diversified portfolios, the drag from persistent hedging often exceeds its benefit.
Hedging vs Position Sizing
Most retail traders don't need complex hedges — proper position sizing achieves the same goal more efficiently. If you never risk more than 1–2% per trade and maintain stop losses on every position, your downside is already capped without the additional cost of a separate hedging structure. Hedging becomes more relevant for institutional-scale portfolios, concentrated positions, or when holding through binary events.
