A credit spread is a foundational options trading strategy employed by investors who aim to profit from an option's premium decay. It involves selling an options contract (either a call or a put) and simultaneously buying another options contract of the same type, on the same underlying asset, and with the same expiration date, but at a different strike price. The key characteristic of a credit spread is that the premium received from selling the option is greater than the premium paid for buying the other option, resulting in an immediate net credit to the trader's account. This net credit represents the maximum potential profit for the strategy. The purpose of buying the second option, often referred to as the ‘wing’ or ‘protection leg,’ is to limit the potential loss should the market move unfavorably against the sold option. For instance, in a call credit spread, an investor sells an out-of-the-money call option and buys a further out-of-the-money call option. This strategy is typically used when the trader expects the underlying asset's price to stay below the short strike. Conversely, in a put credit spread, an investor sells an out-of-the-money put option and buys a further out-of-the-money put option. This is used when the trader expects the underlying asset's price to stay above the short strike. The difference between the strike prices of the two options, minus the net credit received, defines the maximum potential loss. The main appeal of a credit spread lies in its defined risk and potential to generate income, particularly in sideways or moderately bullish (for put spreads) or bearish (for call spreads) markets. It’s a popular choice for traders looking for consistent, albeit smaller, gains over time, accepting a predetermined risk exposure.
The primary goal of a credit spread is to generate income by collecting a net premium. Traders aim for both options in the spread to expire out-of-the-money, allowing them to keep the initial credit as profit.
The two main types are a call credit spread (also known as a bear call spread), which profits if the underlying asset stays below a certain price, and a put credit spread (also known as a bull put spread), which profits if the underlying asset stays above a certain price.
The maximum profit for a credit spread is the net premium received when the strategy is opened. This amount is collected upfront and is kept if both options expire worthless.
