Learn how a bull call spread combines a long call and a higher-strike short call to create a defined-risk bullish options position.
How the strategy is built
Buy one call and sell another call on the same underlying and expiration, using a higher strike for the short leg. The position normally opens for a net debit because the lower-strike call costs more than the higher-strike call brings in.
The market outlook
The strategy fits a moderately bullish forecast. It needs the underlying to rise, but it does not require unlimited upside. The best expiration outcome occurs at or above the short strike, where the spread reaches its maximum width.
Defined profit and loss
Maximum loss is generally the debit paid. Maximum profit is the strike width minus that debit, multiplied by the contract multiplier. The expiration breakeven is the long strike plus the debit per share.
What changes before expiration
Before expiration, delta, gamma, theta and implied volatility affect both legs. The spread may trade below its eventual intrinsic value because time remains, and closing prices can differ from a simple expiration diagram.
A practical example
Buy the 100 call for $6 and sell the 110 call for $2. The net debit is $4, maximum loss is $400, maximum profit is $600 and the expiration breakeven is $104.
This simplified example focuses on the spread at a specific moment and expiration outcome. 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
Is a bull call spread bullish?
Yes. It generally has positive delta and benefits from a rise in the underlying.
Can it lose more than the debit?
A standard spread entered and maintained correctly generally limits expiration loss to the debit plus costs.
Why not buy only the call?
The short call lowers cost and some Greek exposure, but caps the upside.
