Delta Hedging

What Is Delta Hedging?

Delta hedging neutralizes the directional exposure of an options position. Because options have delta — the rate of change in value for each dollar move in the underlying — you can offset that exposure by taking an opposite position in the underlying asset.

If you hold 10 call contracts with 0.50 delta each (500 shares of directional exposure), you would short 500 shares to delta-hedge. As price moves and delta shifts, you adjust the hedge — buying or selling shares to stay near zero net delta.

Why It Matters for Options Traders

Market makers delta-hedge continuously, and this activity drives observable price behavior. When a market maker sells you a call, they buy shares to hedge. As price rises and delta increases, they buy more. As price falls, they sell. This creates feedback loops that can pin prices near large open interest strikes as expiration approaches.

Understanding dealer hedging explains why stocks sometimes act like they’re being “pulled” toward specific levels near expiration, and why large options positions create visible effects in the underlying.

For individual traders, delta hedging isolates volatility exposure. If you believe IV is mispriced but have no directional view, you can buy a straddle and delta-hedge to profit purely from the difference between implied and realized volatility.

The Hedging Cycle

Hedging frequency is a tradeoff. Continuous rebalancing (the theoretical ideal) requires constant trading and generates transaction costs. Discrete intervals (every $1 move, hourly, daily) allow delta drift but reduce costs.

The choice affects P&L due to gamma. Positive gamma positions benefit from frequent hedging — buying dips and selling rallies is mechanically profitable. Negative gamma positions are hurt by the same dynamic.

Gamma scalping is the term for actively trading the hedge to extract profit from a long gamma position.
