When someone buys a call option, they can either choose to excercise it or sell the option to close their position. When excercising the option, they must make sure the price of the stock is above the break even point (strike price plus premium) to profit. However, even if the price of the option contract has risen only slightly above the price that they purchased it, they still profit if they sell the contract. There is no break even point in selling the contract, it just has to go up, right? In general, is it usually more profitable to sell the option contract to close out the position instead of excercising it because when excercising it the stock must go up enough to rise above the break even point? What would be the incentive to excercise the option considering it involves significantly more capital vs. selling the option which gives you virutally the same if not greater profit?
