How risky are covered calls? That's an interesting and important question because selling covered calls is certainly not without risk.
Covered call writing is often touted as a conservative option trading strategy. There is some general truth to the portrayal, but as with all such generalities, not a whole lot of insight.
Unfortunately, the internet is filled with superficial and impartial information written by individuals lacking either the aptitude or the self-interest to drill down on the subjects they cover.
So let's take a few minutes and specifically address the risks associated with writing calls.
I like the How risky are covered calls? question because it gives me the opportunity to reiterate what I think is one of the most important lessons of option trading - namely that options are a risk dial, not a risk switch.
In fact, the main role and original rationale for stock options is to have a vehicle for the trading and management of risk. Options are often seen as risky, but that's only part of the story.
The reality is that options are called options because that's exactly what they give you. Broadly speaking, you can use them to assume the risk of others in exchange for some form of compensation (the basis of credit spreads) or some form of capital gains (the basis of debit spreads).
Of course, it works in the other direction, too. You can use options to, in effect, outsource your own risks (i.e. hedging strategies) in exchange for some form of a cash payment or the sharing of your own position's potential capital gains.
And again, the risk here is a dial, not a switch. With options, it's you, the individual, who determines the level of risk you're willing to assume or what level of risk you desire to outsource.
The more you get this, the less mysterious options are.
If you're at all unfamiliar with this strategy, or just want a refresher, be sure to check out the covered call basics page, or the Covered Calls Overview section for a complete listing of covered call resources this site provides.
Selling calls against stock you own can be seen as a form of reducing the cost basis on those shares by the amount of the premium your receive.
For example, if you buy 100 shares of the XYZ Zipper Company at $30/share and you then proceed to write a $32.50 call on the stock and receive $1/contract in premium (or $100), then assuming the call eventually expires worthless, you have in effect lowered your cost basis from $30/share to $29/share (though not for tax purposes).
That's great, of course, and one of the main reasons why covered calls are seen as conservative - in this example, you just gained a $1/share advantage over a simple buy and hold strategy.
However - and this is a big however - selling calls provides only limited downside protection (and sometimes, depending on how you set them up, almost no downside protection at all).
So what happens if instead XYZ promptly drops to $24/share? That $1/share advantage you held over the buy and hold investor is small comfort when the bottom falls out of your stock.
Upside risk? How can you have upside risk? It's true that you won't lose money if you write a call on a stock and it trades higher through and beyond your strike price.
But here's the key drawback - you won't see any capital gains above that strike price either. And when a stock really breaks out, you're probably going to feel sick at how much money you've left on the table.
In fact, many covered call detractors consider the upside risk to be greater than the downside risk. Remember that selling a call is more or less a neutral to slightly bearish bet (although it's often described as neutral to slightly bullish - I disagree - you may own the stock, but you've also opened a short call option position).
Going back to our XYZ Zipper Company example, what would happen if the stock reported blowout earnings or announced they were going to be acquired at a premium and the stock suddenly shoots up to $40/share?
If you had written the $32.50 call, you'd be looking at an additional $7.50/share in capital appreciation that you're not going to get.
Covered call detractors will point to both of these risks and argue that the entire call writing model is flawed. In fact, it does seem to fly in the face of that old trader's mantra of "Cut your losses quickly and let your winners run."
It forces you to sell stocks that make big moves higher (and without participating in some, most, or all of the capital gains). And it also encourages you to hold on to stocks that are falling. The cynical interpretation then becomes: "Cut you winnings quickly and let you losers run."
Although I understand the validity of this argument, I believe that there are smarter and more effective methods of writing calls that can mitigate much of the inherrent risk.
Remember - options are a risk dial, not a risk switch, and just about any trade can be made to be more conservative or more aggressive.
The better question than "How risky are covered calls?" is the more insightful question, "How risky are you?"
There are, of course, multiple components involved in selling calls. How you address these components determines to a large extent how well you're going to navigate the various risks associated with covered calls.
The components in question are:
