Protective Call
Description
Buying a call to cap the otherwise uncapped upside risk of a short position in the underlying.
Setup
- Sell (short) one unit of the underlying.
- Buy one call option, typically out of the money, as insurance against a rally.
Context
Used by a trader who wants to stay short the underlying for a decline but cannot tolerate the unlimited loss a bare short position carries if it rallies instead.
Risk Profile
Loss is capped at the strike minus the entry price, plus the premium paid for the call. Gain is large but finite, bounded by the underlying reaching zero.
Pros
- Removes the uncapped risk of a naked short position.
- Still profits fully from a decline down to zero.
- Known worst case from the moment the trade is placed.
Cons
- Call premium is a drag on returns if the underlying does not move.
- Costs more to carry than a bare short position.
- Reward, while large, is not unlimited.
Effect of Time
Time decay works against the long call, quietly eroding the cost of the insurance each day.
Effect of Volatility
Rising implied volatility increases the cost of the protective call but also increases its value as a hedge.

Estimated Cost to Assemble
An estimate of what entering this structure right now would really cost: filling every leg by crossing the spread (the ask when buying, the bid when selling) instead of at the mid-price, plus an estimated exchange fee. Real fees and fills can differ from this estimate.
Payoff & Greeks vs. Underlying Price
The Greeks curves are a Black-Scholes model using each leg's current implied volatility, holding time to expiry fixed -- not live exchange data at every price, which only exists at the current price (dashed line).
Payoff at Expiration
This structure's value and profit/loss at expiration, at a handful of specific prices: every leg's strike, every breakeven, the current spot, and the chart's own range.
