However, it may be lumped together with a strategy like option buying, which carries much more risk but still not as much as strategies such as writing naked calls. To initiate a naked option position, you must not only acquire preapproval but also secure the position with a hefty amount of cash or margin. If you are approved for covered writing but not naked writing, then you must always have or purchase the stock before selling calls against it. If you want to sell the call first and try to buy the stock at a lower price sometime later, your broker will not let you unless you are approved to sell naked options (which is not a recommended practice, anyway).

The appeal of buying a call is, of course, the ability to enjoy substantial upside potential with a limited investment and consequently a limited potential loss. The call buyer knows that the process will lose money frequently, if not most of the time. That’s because, for the position to gain, the stock must not only go up but must go beyond the call buyer’s breakeven point—the strike price plus the call premium by expiration.
