A bull put spread is a defined-risk, defined-reward options strategy employed by traders who believe an underlying asset's price will either rise moderately or stay above a certain level by expiration. It is constructed by simultaneously selling an out-of-the-money (OTM) put option and buying a further OTM put option with the same expiration date and on the same underlying asset. The strike price of the put option sold is higher than the strike price of the put option bought. Because the option sold has a higher strike price and is closer to the money, it typically has a higher premium than the option bought. This results in an initial net credit to the trader's account when the spread is opened, which is the maximum potential profit for the strategy. The purpose of buying the lower strike put option is to hedge against a significant downward move in the underlying asset, thereby defining the maximum potential loss. The maximum loss occurs if the underlying asset's price falls below the strike price of the bought put option by expiration. The strategy is profitable if the underlying asset's price stays above the strike price of the sold put option at expiration, allowing both options to expire worthless and the trader to keep the initial credit. If the price ends up between the two strike prices at expiration, the sold put option will be in-the-money while the bought put will be out-of-the-money, leading to a partial loss. Understanding the strike prices, expiration dates, and the implied volatility of the options involved is crucial for successful implementation of a bull put spread.
A bull put spread is typically used when an options trader has a moderately bullish or neutral outlook on an underlying asset. This means they expect the asset's price to either rise slightly or remain stable above a certain level by the option's expiration date.
The maximum profit for a bull put spread is the net credit received when opening the position, minus any commissions. This occurs if both put options expire out-of-the-money, meaning the underlying asset's price is above the higher strike price at expiration.
The maximum loss for a bull put spread is calculated as the difference between the strike prices of the two puts, minus the net credit received, plus any commissions. This loss occurs if the underlying asset's price falls below the lower strike price at expiration.
