Bull Call Spread Explained
Debit vertical: buy a lower-strike call and sell a higher-strike call. Bullish with defined risk and defined reward.
How a Bull Call Spread is built
Buy call at K1, sell call at K2 (K2 > K1), same expiration.
- Leg 1: buy call · strike template 100 · premium ~4 · 1 contract(s)
- Leg 2: sell call · strike template 110 · premium ~1.5 · 1 contract(s)
Risk & reward snapshot
| Market bias | bullish |
|---|---|
| Max profit | Width (K2 − K1) − net debit paid. |
| Max loss | Net debit paid. |
| Breakeven | Long call strike + net debit. |
Figures are conceptual for the classic structure. Your actual premiums, strikes, and fees change the numbers — confirm on the calculator.
When traders use it
- Moderately bullish: you expect a rise but want cheaper risk than a naked long call.
- You accept capped upside in exchange for lower cost.
Key risks
- If the stock stalls, both calls can decay; debit is fully at risk.
- Early assignment risk on short call if deep ITM near expiration.
Practical tips
- Wider spreads cost more and need larger moves; tighter spreads are cheaper but cap sooner.
- Compare to a long call on the calculator for cost vs upside.
