A bull call spread, also called a long call spread or call debit spread, buys a call at one strike and sells a call at a higher strike with the same expiration. The sold call reduces the cost of the bought call, but it also caps the profit. The result is a bullish position with a defined maximum loss, a defined maximum gain and a lower break even than a single call. It suits traders who expect a moderate rise to a target, rather than an explosive move.

## Construction

1. **Buy a call** at a lower strike (often at or near the money).
2. **Sell a call** at a higher strike (near your price target).
3. **Same underlying, same expiration.**
4. **Pay a net debit.**

## Payoff at a glance

| Feature | Bull call spread |
|---|---|
| Outlook | Moderately bullish |
| Maximum loss | Net debit |
| Maximum gain | Strike width minus net debit |
| Break even at expiry | Lower strike + net debit |
| Time decay | Mixed: hurts below the strikes, helps above |
| Implied volatility | Small net effect |

## Worked example

**Example: A bull call spread vs a single call**
A stock trades at $200. You expect a rise to about $215 within six weeks.

- **Single call:** buy the $200 call for $8.00 ($800).
- **Bull call spread:** buy the $200 call for $8.00, sell the $215 call for $3.00. Net debit $5.00 ($500).

| Stock at expiry | Single call | Bull call spread |
|---|---|---|
| $190 | minus $800 | minus $500 |
| $205 | minus $300 | $0 (break even) |
| $215 | +$700 | +$1,000 (maximum) |
| $230 | +$2,200 | +$1,000 |

The spread wins if the stock rises moderately; the single call wins only if it rises far beyond $215. The spread also loses less if you are wrong.

## Why choose a bull call spread

- **Lower cost** than buying a call alone.
- **Lower break even,** since the debit is smaller.
- **Less exposure to implied volatility:** the short call offsets much of the long call's vega, which helps around events like earnings. See [Vega](https://learn.tradelabsai.com/options/vega/).
- **Less time decay** than a single call, because the short call's decay offsets part of the long call's.

The trade off is capped profit above the higher strike.

## Choosing strikes

| Choice | Effect |
|---|---|
| Buy at the money, sell near target | Common balance of cost and reward |
| Buy in the money, sell at the money | Higher probability, lower reward to risk |
| Buy and sell out of the money | Cheap, low probability, high reward to risk |
| Wider spread | Larger gain and loss |

A useful guide: set the short strike at a level the stock can realistically reach by expiry, such as a resistance level or a measured move target. See [Support and Resistance](https://learn.tradelabsai.com/price-action/support-and-resistance/) and [Profit Targets](https://learn.tradelabsai.com/position-management/profit-targets/).

## Choosing expiration

Allow enough time for your move. Spreads reach close to maximum value only near expiration, unless the stock moves far past the short strike. If you expect a move within a month, an expiry of six to eight weeks gives room. See [Option Expiration Dates](https://learn.tradelabsai.com/options/option-expiration-dates/).

## Managing the trade

- **Take profits** at 50% to 80% of maximum gain; the last part takes longest to earn.
- **Cut losses** if the thesis breaks, for example if price breaks a key support.
- **Close before expiry** if price is between the strikes, to avoid assignment complications.
- **Roll up** if the stock rises quickly and you remain bullish: close the spread and open one at higher strikes.

## Assignment risk

If the short call is in the money, it can be assigned early, especially before an ex dividend date. You would become short shares, still protected by your long call. Closing the spread or exercising the long call resolves it. See [Exercise and Assignment](https://learn.tradelabsai.com/options/exercise-and-assignment/).

## Common mistakes

- **Setting the short strike too close,** capping profit at a level easily exceeded.
- **Buying too little time.**
- **Holding to expiry for the last few cents.**
- **Ignoring the combined bid ask spread** of two legs; use a single limit order for the spread.

## Frequently asked questions

### What is a bull call spread?

Buying a call and selling a higher strike call with the same expiry, creating a bullish trade with limited risk and limited profit.

### What is the maximum profit on a bull call spread?

The difference between the strikes minus the net debit paid, reached when the underlying is at or above the higher strike at expiry.

### Is a bull call spread better than buying a call?

It is cheaper and has a lower break even, but caps profit. It suits moderate moves; a single call suits large moves.
