What Is a Bull Call Spread Option? A Comprehensive Overview
Editor's Note: Options are not suitable for all investors. Options involve risks, including substantial risk of loss and the possibility an investor may lose the entire amount invested in a short period of time. Please see the Characteristics and Risks of Standardized Options.
A bull call spread, also known as a long call spread or a type of vertical spread, is an options trading strategy used to capitalize on moderate price increases for a stock. The strategy involves buying a call option at a lower strike price and selling a call option at a higher strike price.
Investors use a bull call spread when they’d like to take advantage of a slightly bullish trend in a stock without taking too much risk. This type of options trading strategy limits both profits and losses, making it a popular strategy for investors with limited capital and a desire for downside protection.
Key Points
• A bull call spread benefits from a moderately bullish stock trend while limiting risk and upfront costs.
• The spread’s value increases as the stock price increases, but when it falls, losses are limited by the short call.
• Volatility has minimal impact due to near-zero vega, with long and short calls offsetting each other.
• Time decay affects the spread negatively if the stock price is below the lower strike, positively if it’s above the higher strike.
• Pros include lower cost and limited losses, while the main con is capped potential gains.
What Is a Bull Call Spread Position?
To initiate a bull call spread, options traders buy a call option at a lower strike price while selling a call with a higher strike price. Both options have the same expiration date and underlying asset.
This options strategy establishes a net debit or cost and makes money when the underlying stock rises in price. The potential profits hit a limit when the stock price rallies above the strike price of the short call (the leg sold with the higher strike price), while potential losses hit a limit if the stock price declines beneath the strike price of the long call (the leg bought with the lower strike price).
In a bull call spread, a trader cannot lose more than the net premium, plus commissions. A trader’s maximum gain is the difference between the strike prices of the short and long call minus the net premium, plus commissions.

Bull Call Spread Example
Let’s say a trader establishes a bull call spread by purchasing a call option for a premium of $10 (the long call). The call option has a strike price of $50 and expires in three months. The trader also sells (or writes) a call option for a premium of $2 (the short call). The call option has a strike price of $70 and expires in three months. The underlying asset of both options is the same and currently trades at $50.
Since options contracts typically cover 100 shares, the trader’s total net cost would be $8 per share x 100 shares, or $800.
Assume that three months have passed and the expiration date has arrived.
Scenario 1: Maximum Profit
If the stock price is $60 or above at expiration, both calls would be in-the-money. The maximum gain can be determined by subtracting the net premium paid for the options from the difference between the two strike prices. In this example, the maximum profit for the trader would be $1,200, minus any commissions or fees.
• Strike price difference: $70 – $50 = $20 per share
• Less net premium paid: $20 – $8 = $12 per share
• Total max profit: $12 x 100 = $1,200
Scenario 2: Maximum Loss
If the stock price is $50 or lower at expiration, both options expire worthless. The maximum potential loss would be the net premium paid upfront, plus any commissions or fees.
• The trader loses the entire initial $8 per share investment
• Max loss = $8 x 100 shares = $800
Scenario 3: Breakeven Price
The breakeven occurs when the total gain offsets the initial cost, which can be determined by adding the net premium ($8) to the long call strike price ($50), which results in a breakeven price of $58.
• Long call gains = (Stock price – $50) x 100
• Breakeven price = $50 + $8 = $58
Variables Impacting a Bull Call Spread
As with any options trading strategy, various potential factors can have an effect on how the trade will play out. The ideal market forecast for a bull call spread is “modestly bullish,” or that the underlying asset’s price will gradually increase.
As with all options, the price of the underlying security is only one of several factors that can impact the trade.
Stock Price Change
A bull call spread will increase in value as its underlying stock price rises and decline in value as the stock price falls. This kind of position is referred to as having a “net positive delta.”
Delta estimates how much the price of an option is expected to change for every $1 change in the underlying security’s price. The change in option price is usually less than that of the stock price. For example, if the stock price falls by $1, the option may only fall by $0.50.
Change in Volatility
Volatility refers to how much a stock price fluctuates in percentage terms. Implied volatility (IV) is a factor in options pricing. When volatility rises, option prices often rise if other factors remain unchanged.
Because a bull call spread consists of one short call and one long call, the price of this position changes little when volatility changes (an exception may be when higher strike prices carry higher volatility). In options vocabulary, this is called having a “near-zero vega.” Vega is an estimation of how much an option price could change with a change in volatility, assuming all other factors remain constant.
Time
Time is another important variable that influences the price of an option. As expiration approaches, an option’s total value decreases, a process called time decay.
The sensitivity to time decay in a bull call spread depends on where the stock price is in relation to the strike prices of the spread. If the stock price is near or below the strike price of the long call (lower strike), then the price of the bull call spread declines (and loses money) as time passes. Conversely, if the stock price is above the higher strike price, time decay works in favor of the trader, as the short call loses value faster than the long call.
On the other hand, if the price of the underlying stock is near or above the strike price of the short call (higher strike), then the price of a bull call spread rises (and makes money) as time passes. This occurs because the short call loses time value faster than the long call, which benefits the trader. The long call is deep in-the-money, and therefore primarily composed of intrinsic value (and less affected by time decay).
In the event that the stock price is halfway between both strike prices, time decay will have little impact on the price of a bull call spread. In this scenario, both call options decay at more or less the same rate.
Risk of Early Assignment
Traders holding American-style options can exercise them on any trading day up to the expiration date. Those who hold short stock options have no control over when they may have to fulfill the obligation of the contract.
The long call in a bull call spread doesn’t face early assignment risk, but the short call may be subject to the risk of early assignment. Calls that are in-the-money and have less time value than the dividends that a stock pays are likely to be assigned early.
This can happen because when the dividend payout is greater than the price of the option, traders would rather hold the stock and receive the dividend. For this reason, early assignment of call options usually happens the day before the ex-dividend date of the underlying stock (the day by which investors must hold the stock in order to receive the dividend payout).
When the stock price of a bull call spread is above the strike price of the short call (the call with a higher strike price), traders must determine the likelihood that their option could be assigned early. If it looks like early assignment is likely, and a short stock position is not desirable, then a trader must take action.
There are two ways to do away with the risk of early assignment. Traders can either:
• Close the entire spread by buying the short call to close and selling the long call to close, or
• Buy to close the short call and leave the long call open.
Pros and Cons of Using a Bull Call Spread
The main advantages of using a bull call spread is that it costs less than buying a single call option and limits potential losses. In the earlier example, the trader would have had to pay a $1,000 premium ($10 for 100 shares) if they had only been using one call option. With a bull call spread, they only have to pay a net of $800 ($8 for 100 shares).
The potential losses are also capped. If the stock were to fall to zero, the trader would realize a loss of just $800 rather than $1,000 (if they were using only the long call option).
The biggest drawback of using a bull call spread is that it caps potential gains. In the example above, our trader only realized a maximum gain of $1,200 because of the short call option position. In the event that the stock price were to soar to $400 or higher, they would still only realize a $1,200 profit.
The Takeaway
A bull call spread is a two-leg options trading strategy that involves buying a long call and writing a short call. Traders use this strategy to try and capitalize on moderately bullish price momentum while capping both losses and gains.
As with all trades involving options, there are many variables to consider that can alter how the trade plays out.
