Bull Call Spread
Cheaper defined-risk bullish bet. Outlook: bullish. Direction: debit. Risk: defined.
A bull call spread (also called a debit call spread) is built by buying a closer-to-money call and simultaneously selling a further-OTM call at a higher strike. The short call reduces the cost of entry but caps upside at the short strike.
This is the classic cheaper bullish bet structure. Compared to a naked long call, the spread has lower breakeven, lower max loss, and lower max profit — a better risk/reward when you think a modest up-move is likely but a huge one is not.
Break-Even
Break-even = long-strike + net debit paid.
Max Profit
(Spread width − net debit) × 100 × contracts, achieved if spot is at or above the short strike at expiration.
Max Loss
Net debit × 100 × contracts, realized if spot is at or below the long strike at expiration.
When to Use
- You expect a moderate up-move — not enough to justify an uncapped long call.
- IV is elevated — selling the short leg recovers some of the expensive premium.
- You want defined-risk exposure with a clear max-loss number going in.
- Budget constraint: spreads are meaningfully cheaper than outright long calls.
Common Pitfalls
- Capped upside: if the stock rallies beyond the short strike, you do not participate.
- Both legs are long-vega overall — IV crush can hurt even on a favorable move.
- Time decay is slower than a naked long call but still works against you.
- Assignment risk on the short leg: ITM short calls near expiration can be assigned.
