A call spread options strategy combines buying and selling call options on the same stock with different strike prices to limit risk while maintaining upside potential. This strategy typically involves two calls: one bought at a lower strike price and another sold at a higher strike price.
Call spreads work by creating a range of profitability. The trader pays a net debit (cost) for the spread, which is lower than buying the lower-strike call outright. The maximum profit is capped at the difference between the strike prices minus the net debit paid. The maximum loss is limited to the net debit paid.
For example, if a trader buys a call option with a $50 strike price for $2 and sells a call option with a $55 strike price for $1, the net debit is $1 per spread. The maximum profit is $4 minus the $1 net debit, or $3 per spread. The maximum loss is $1 per spread.
There are two primary types of call spreads:
| Type | Description | Market Outlook |
|---|---|---|
| Bull Call Spread | Buy a call at a lower strike, sell a call at a higher strike | Moderately bullish |
| Bear Call Spread | Sell a call at a lower strike, buy a call at a higher strike | Moderately bearish |
Traders use call spreads to limit their risk while still participating in potential stock price movements. The strategy reduces the cost of entering a position compared to buying a call option outright. Call spreads are also used to generate income through the sale of the higher-strike call.
According to the Chicago Board Options Exchange (CBOE), call spreads are popular among traders because they offer a defined risk/reward profile. This makes them attractive for both conservative and aggressive traders.
One common misconception is that call spreads are only useful in bullish markets. However, bear call spreads can be used in moderately bearish markets to profit from a decline in the stock price.
Another mistake is assuming that call spreads eliminate all risk. While they limit risk compared to other strategies, they still carry the potential for loss. The key advantage is that the maximum loss is known upfront.
Suppose XYZ stock is trading at $50. A trader wants to use a bull call spread expecting the stock to rise moderately. They buy a $50 call for $2 and sell a $55 call for $1. The net debit is $1 per spread.
If XYZ rises to $56 at expiration, the $50 call is worth $6 ($56 - $50), and the $55 call is worth $1 ($56 - $55). The trader profits $4 ($6 - $1) on the spread, minus the $1 net debit, resulting in a $3 profit per spread.
If XYZ stays at $50, both options expire worthless, and the trader loses the $1 net debit. If XYZ drops below $50, the same loss occurs.
This strategy limits the trader's risk to the net debit paid while providing a defined reward if the stock moves favorably.
