Buy a call at strike K1, sell a call at strike K2 (K2 > K1). The sold call partially finances the bought call. You profit from moderate price rises.
When to use: You are moderately bullish, expect a price rise to approximately K2, but want to risk less capital than with a pure long call.
| Metric | Formula | Example (K1=$100, K2=$110, Net Debit $4) |
|---|---|---|
| Max. Profit | (K2 − K1 − Net Debit) × 100 | +$600 |
| Max. Loss | −Net Debit × 100 | −$400 |
| Breakeven | K1 + Net Debit | $104 |
