A bull call spread consists of one long call with a lower strike price and one short call with a higher strike price.
You have been researching a stock and have formed a bullish opinion on its value, forecasting that it will rise in price over the coming months. You would like to limit your risk and are comfortable paying money to establish this position.
Building on your foundational knowledge of call and put options as well as the risks and benefits of single-leg options trades (buy call, sell call, buy put, sell put), you recognize that a two-leg trade, or spread trade, achieves the objectives you have outlined.
Specifically, buying a call expresses your bullish sentiment and achieves the goal of limiting your risk exposure to the downside. By selling a higher strike call, you offset some of the cost of the long position and also trade off some of the upside gain potential.
The combination of a long call and short call is referred to as a spread trade. Risks and benefits of each individual option component, or leg, offset each other to a degree in order to create the desired position and range of possible outcomes.
A bull call spread consists of one long call with a lower strike price and one short call with a higher strike price:
Both calls have the same underlying stock and the same expiration date.
A bull call spread is established for a net debit (or net amount paid) and profits from a rising stock price.
Both maximum profit and maximum risk (loss) are limited and known.
Worth noting: The “bull call spread” strategy is also known as a “long call spread” and as a “debit call spread.” The term “bull” refers to the fact that the strategy profits with bullish, or rising, stock prices. The term “long” refers to the fact that this strategy is “long the market,” which is another way of saying that it profits from rising prices. Finally, the term “debit” refers to the fact that the strategy is created for a net cost, or net debit.
In our example, assume stock XYZ is currently trading around $100.
We buy 1 XYZ 100 call for a total of $330 (1 x 100 multiplier x $3.30) and sell 1 XYZ 105 call for a total of $150 (1 x 100 multiplier x $1.50).
In this example the bull call spread (long call + short call) positions were established for a net debit of $180 (–$330 + $150 = –$180).
With a bull call spread position, potential profit is limited because of the short call.
First, let’s recall the formulas for individual options positions:
Long Call Profit = Current Stock Price – Strike Price – Net Premium Paid
Short Call Loss = – (Current Stock Price – Strike Price – Net Premium Received)
Short Call Profit = Net Premium Received
Long Call Loss = Net Premium Paid
To calculate our profit on the position we established, we use the formula:
Profit = Profit/Loss on Long Call + Profit/Loss on Short Call
The maximum profit of the bull call spread is limited to the difference between the strikes minus the net premium paid. This maximum profit is realized if the stock price is at or above the strike price of the short call (higher strike).
Stock XYZ is trading at $100 and you establish a bull call spread for a $1.80 debit.
A week later, stock XYZ is trading higher at $108.
*Unrealized profits are those that potentially exist; realized profits occur when you close out or trade out of the position.
Let’s assume we are incorrect in our sentiment, and the stock price declines. To calculate our loss on the position, use the following formula:
Loss = Profit/Loss Long Call + Profit/Loss Short Call
Remember, the stock price cannot trade below $0. Maximum loss is equal to the net premium paid.
Max Loss = Net Premium Paid = $1.80 per share or $180 total loss (not including transaction costs and fees)
Stock XYZ experiences unexpected news and is now trading lower at $97.
*Unrealized profits are those that potentially exist; realized profits occur when you close out or trade out of the position.
The breakeven price calculated on a per share basis for a bull call spread is equal to the long call (lower strike) less the net premium paid.
Breakeven Price = Long Call Strike + net premium paid – commissions and fees
Breakeven Price = $100 + $1.80 = $101.80
Early assignment risk applies to short options positions only.
American options can be exercised on any business day, and the holder of a short stock options position has no control over when they will be required to fulfill the obligation. Therefore, the risk of early assignment must be considered when entering positions involving short options. Early assignment of stock options is generally related to dividends.
The long call (lower strike) in a bull call spread has no risk of early assignment.
The short call (higher strike) does have such risk.
If the stock price is above the strike price of the short call in a bull call spread (the higher strike price), an assessment must be made if early assignment is likely. If assignment is deemed likely and if a short stock position is not wanted, then appropriate action must be taken. Before assignment occurs, the risk of assignment can be eliminated in two ways:
If early assignment of a short call does occur, stock is sold. If no stock is owned to deliver, then a short stock position is created. If a short stock position is not wanted, it can be closed by either buying stock in the marketplace or by exercising the long call. Note, however, that whichever method is chosen, the date of the stock purchase will be one day later than the date of the stock sale. This difference will result in additional fees, including interest charges and commissions. Assignment of a short call might also trigger a margin call if there is not sufficient account equity to support the short stock position created by the option assignment.
There are three possible outcomes at expiration: the stock price can be at or below the lower strike price, above the lower strike price but not above the higher strike price, or above the higher strike price:

All investments involve risk, and not all risks are suitable for every investor. The value of securities may fluctuate and as a result, clients may lose more than their original investment. The past performance of a security, or financial product does not guarantee future results or returns. Keep in mind that while diversification may help spread risk, it does not assure a profit or protect against loss in a down market. There is always the potential of losing money when you invest in securities or other financial products. Investors should consider their investment objectives and risks carefully before investing.
Diversification does not eliminate the risk of experiencing investment losses. Margin trading increases risk of loss and includes the possibility of a forced sale if account equity drops below required levels. Margin is not available in all account types. Margin trading privileges are subject to Webull Financial, LLC review and approval. Leverage carries a high level of risk and is not suitable for all investors. Greater leverage creates greater losses in the event of adverse market movements.
