This strategy involves being short on a stock future to take advantage of downward price movements, while purchasing a call option to limit losses from an unexpected price rise. The investor shorts a stock future and buys an at-the-money or slightly out-of-the-money call option. If the stock price falls, the investor profits from the short future position. However, if the price rises unexpectedly, the call option limits losses. The maximum risk is limited to the call strike price minus the stock price plus the premium paid. The maximum reward occurs if the stock price falls to the call strike price minus the premium.
