Consider the following scenario:
One takes an option call sell position now. A week later, the underlying's price hits the strike price of the call sell position, with no signs of abating. One immediately buys future as an hedge. And if the price starts getting below the Strike Price, he squares off the future.
Is buying future a good strategy to avoid the pains of having to roll over the sell call - which invariably happens at a loss? Are there any hidden costs? Assume that the person doesnt have any margin constraints.
