What Is Delta Hedging?
Delta hedging neutralises an option position’s directional risk. Here’s the concept, simply explained.
On this page
Delta hedging is a technique to reduce or neutralise the directional risk of an options position by taking an offsetting position in the underlying. It’s widely used by market makers and advanced traders.
The role of delta
Delta (one of the option Greeks) measures how much an option’s price moves for a ₹1 move in the underlying. A call with 0.5 delta gains ~₹0.50 per ₹1 rise. Delta hedging uses this to cancel out directional exposure.
How it works
If you’ve sold a call with 0.5 delta on 100 shares, your position loses as the stock rises. To hedge, you buy ~50 shares (0.5 × 100) of the underlying — so a small move in the stock barely changes your net position. You’ve become roughly "delta neutral", profiting instead from other factors (like time decay or volatility) rather than direction.
The catch: it’s dynamic
Delta changes constantly as the stock moves and time passes (that’s "gamma"). So a delta hedge must be rebalanced repeatedly to stay neutral — which incurs transaction costs and is operationally demanding.
Why it matters to you
Most retail investors won’t delta-hedge actively, but understanding it explains:
- How market makers manage risk while quoting options.
- Why option prices behave as they do around big positions.
It’s an advanced concept — useful to understand, rarely necessary to execute as a retail trader. Options are high-risk. Education only, not advice.
