Learn how shares or options can offset directional exposure, why hedges drift and what risks remain after reaching zero delta.
Create the initial hedge
A long option position with +60 share-equivalent delta can be offset initially by shorting about 60 shares. A negative-delta position can be offset with positive shares or other positive-delta instruments.
Rebalancing
When the underlying moves, option delta changes. A delta hedge therefore requires monitoring and possible rebalancing. Frequent adjustments can reduce directional exposure but increase costs and execution risk.
What remains
A delta-neutral portfolio can still have gamma, theta, vega, gap and liquidity risk. Hedging is a risk transformation rather than a guarantee, and overnight jumps may occur before a hedge can be adjusted.
A practical example
A trader owns calls with +75 total delta and shorts 75 shares. After a rally, positive gamma lifts option delta to +92, so the portfolio is now +17 delta before rebalancing.
This simplified example holds other inputs constant to isolate directional exposure. Live option prices also reflect the underlying price, time decay, rates, dividends, liquidity and transaction costs. Greeks are theoretical estimates, not guarantees.
Frequently asked questions
Does delta hedging lock in profit?
No. Other Greeks, gaps and trading costs remain.
How often is a hedge adjusted?
It depends on risk limits, gamma, market movement and costs.
Can another option hedge delta?
Yes, though it also adds its own gamma, theta and vega.
