Bull Call Spread
Bet on a stock going up — with a safety net on the cost.
Beginner
Bullish
Defined risk, defined reward — lower cost than buying a call outright
The Simple Version
Plain English — no jargon
You think a stock is going up, but buying a call option is expensive. So you buy a call at $100 strike AND sell a call at $110 strike. The second one you sell pays for part of the first one. You cap your profit at $110, but you also cap your cost. Cheaper entry, defined max loss, defined max gain.
How It Works — Step by Step
- 1 Buy a call option at a lower strike (your bullish bet)
- 2 Sell a call option at a higher strike (reduces your cost)
- 3 Net debit paid = your maximum loss
- 4 Maximum profit = difference between strikes minus net debit
- 5 Profit if stock rises above the upper breakeven at expiration

When to Use It — and When Not To
✓ Use when
- You are bullish but want to reduce premium cost vs. a naked long call
- You have a specific price target in mind for the stock
- IV is high — selling the upper call offsets the expensive lower call
✗ Avoid when
- You expect a massive move — the spread caps your profit
- IV is low — little benefit to selling the upper call
- You are very short-term — spread needs time to develop
Greeks & Mechanics (for the experienced trader)
Delta
Positive — profits from upward stock movement.
Theta
Slightly negative — time decay hurts the long call more than it helps the short call.
Vega
Slightly positive — benefits mildly from rising IV.
Gamma
Positive but reduced — the short call offsets some gamma of the long call.
Key Risks
- Max loss is the net debit paid — entire premium can be lost if stock falls
- Profit is capped at the upper strike — you miss any move beyond it
- Both legs must be managed at expiration to avoid assignment risk
