A call spread is an options strategy that involves buying and selling call options on the same underlying asset, with the same expiration date, but at different strike prices. It’s typically used to express a bullish view with defined risk and capped reward.
Structure of a Call Spread
- Buy a call option at a lower strike price (more expensive)
- Sell a call option at a higher strike price (less expensive)
- Same expiration date
Key Traits of Call Spreads
| Feature | Description |
|---|---|
| Net Debit | Trader pays to enter the position (cost of long call minus premium from short call) |
| Limited Upside | Max profit occurs if the stock closes at or above the short call strike |
| Defined Risk | Max loss is the net debit paid upfront |
| Directional Bias | Bullish, but more conservative than buying a naked call |
Why Use Call Spreads?
- Reduces cost compared to buying a single call
- Ideal for targeted moves where you expect moderate upside
- Useful around macro catalysts, earnings, or technical breakouts

Summary
This strategy involves pairing two option contracts on the same stock with identical expiration dates but different strike prices—buying the lower and selling the higher. It’s designed to profit from moderate upward movement in the underlying asset while keeping both risk and reward clearly defined. The upfront cost is limited, and the maximum gain is capped at the difference between the strikes minus that cost. Traders often use it to express a directional view without the full exposure of a single long option, especially around earnings, macro events, or technical breakouts
