Bull Call Spread

Capital-efficient bullish strategy with capped risk

The bull call spread consists of buying an ATM or slightly ITM call and simultaneously selling an OTM call with a higher strike. The purchased call participates in the upward move; the sold call partially finances it and caps maximum profit. You pay a net debit for this strategy, which is also your maximum loss. Compared to buying a single call, the bull call spread is significantly cheaper.

Advantages

  • Significantly cheaper than single long calls (short call finances premium)
  • Clearly defined maximum loss (debit paid)
  • Fully participates in price gains up to the short strike
  • Better return-to-risk ratio than direct stock purchase with limited capital

Risks

  • Maximum profit capped (price gains above the short strike are not captured)
  • Time decay works against you (debit trade)
  • Two option transactions mean more bid-ask spread costs
  • More complex to manage than a simple long call
Timing

When to Use

2IV is currently elevated (expensive to buy single calls)
3Limited capital or desire for defined maximum loss
4Price target near the short call strike
530-60 days to expiration to allow enough time for the move

FAQ

Frequently Asked Questions

When is a bull call spread better than a single long call?
A bull call spread makes more sense than a long call when (a) IV is high and single calls are expensive — the short call significantly reduces the IV premium; (b) you have a specific price target and don't need upside beyond that; (c) you want to cap your loss risk at a specific amount. A single long call pays off more with low IV or when you want unlimited upside.
How do I choose strikes for a bull call spread?
Buy the call at or slightly above the current price (ATM to slightly ITM). Sell the call at your price target — typically 5-10% above the current price. Wider spreads (10-15%) cost more debit but have more profit potential. Narrower spreads (3-5%) are cheaper but maximum profit is smaller. A 1:3 to 1:4 cost-to-reward ratio is considered attractive.
What happens to my bull call spread at expiration?
At expiration, three scenarios: (1) Price below long strike → both calls expire worthless → full debit lost. (2) Price between strikes → long call has intrinsic value, short call expires → partial gain. (3) Price above short strike → maximum profit = spread width minus debit. Brokers often automatically settle spreads — check your broker's contract terms.
How does time decay affect my bull call spread?
Theta (time decay) works against a bull call spread, but less severely than with a single long call. The short call also loses time value, partially offsetting the theta damage of the long call. The further the price is from the long strike, the more damage theta does. Near the long strike or in-the-money, the spread has less time value sensitivity.
What is the maximum profit on a bull call spread?
Maximum profit is (short strike − long strike − net debit) × 100 per contract. Example: long call at 100, short call at 110, debit 3 → max profit = (110 − 100 − 3) × 100 = $700. This maximum profit is achieved when the price is above 110 at expiration. The ratio of maximum profit to maximum loss (7:3 in this example) demonstrates the capital efficiency of the strategy.
