There are two basic choices in hedging a call option position--establishing a short position in the stock or buying put options. Since a call option position is a "long" position--that is, an investment that will profit if the price of underlying stock goes up--in order to hedge that position you must have an investment that will increase in value as the original call position decreases in value.

Hedging is often done when the position is already profitable and you want to protect those profits, so it can be thought of as a form of insurance. Determine how much of a hedge you want.

Once you have decided the percentage, then you can calculate how much you will have to invest to hedge that percent of the value of your calls. Decide whether you want to hedge your call position by buying offsetting put options or by establishing a short position in the underlying stock. The factors to consider in making this decision are the amount of capital you want to tie up in this hedge and the premium on the put options.
