Many new option traders like to trade covered calls but they do so without really understanding their risk exposure. In this article we will discuss just what those risks are and lay out some of the key drawbacks in writing covered calls.


First, it is important to understand that before traders can write a covered call, they must own the stock. Option contracts are written in 100-share increments, so traders need to buy at least 100 shares of the stock they want to write a call on. Given this, it is easy to see how it can require a lot of capital outlay on many blue chip stocks trading at $60 per share or more.

In addition to the large capital outlay, another big drawback that must be pointed out is that the price of the underlying stock could decline severely. In this situation, traders cannot sell the stock; they are locked in until expiration date because by writing a covered call traders have the obligation to sell their stock at a set price until the expiration date. In this particular case traders buy back the call, which ends their obligation and frees up the stock to be sold.

Another possibility that must be considered if writing covered calls is that a stock might really start to takeoff unexpectedly. In this case, traders experience an opportunity loss in that after the stock has exceeded the strike price used plus the premium received, and they no longer gets to participate in the upward movement of the stock—which is why it is referred to as an opportunity loss.

Even though covered call writing is more attractive when volatility is high, it is much better for the options strategist to use combination strategies like bull call spreads, bull put spreads and other even more advanced type strategies. By using option combinations instead of covered calls traders have a far less capital outlay as well as improving their particular risk-to-reward profile significantly. Please keep these facts in mind about the covered call when considering its implementation.

Happy Trading.
