Many investors looking to generate income come across covered calls at some point during their research. While there are plenty of explanations about why covered calls are beneficial, understanding the risks can be a little more challenging. But understanding these risks is essential to securing desirable target financial outcomes. Let’s take a closer look at the risks and downsides of covered calls and whether the benefits outweigh them.Covered calls aren't risk-free – here are the risks to remember and strategies you can use to mitigate them.

Covered calls are an options strategy that involves selling a call option against an existing long stock position. In effect, the call option caps the upside potential of the long stock position in exchange for an immediate option premium. As a result, many investors use covered calls to generate income on stocks with a neutral to mildly-bullish outlook.

There are several reasons to use covered calls:
Covered calls are a low-risk option strategy, but that doesn’t mean they’re risk-free. On the contrary, covered calls entail the same risks as long stock ownership with more limited upside potential. As a result, investors must ensure the income generated from these strategies offset the potential costs and deliver on their investment objectives.
The two most significant risk factors include:

Covered calls tend to underperform during bull markets and outperform during bear markets. After all, when stock prices are rising, there’s a significant opportunity cost. And when stock prices are falling, covered calls provide a buffer against some of the losses. So, investors should always consider these risks in the broader market context.
Covered calls may be relatively low risk, but is the income worth the downside risk or opportunity cost?
The Sharpe ratio is a common way to measure risk-adjusted returns. In effect, it measures the return earned above the rate of return on risk-free short-term U.S. Treasuries relative to the risk taken. Since covered calls inherently reduce volatility by limiting upside, they result in a higher Sharpe ratio than holding the long equity position alone.
Of course, the Sharpe ratio doesn’t account for the skewness of returns. Capping the upside potential of a stock may reduce volatility, but it increases the negative skewness of returns. As a result, investors would be better off using the Sortino ratio, which only penalizes returns falling below an investor-specified target.
In addition to overcoming negative skewness, the benefits of covered calls must exceed the higher tax and transaction costs. For example, frequently writing covered calls or buying and selling underlying stock may trigger commissions and short-term capital gains. Meanwhile, you typically pay short-term capital gains on any option premium income. Taxes aren’t a concern in retirement accounts, so many retirees choose to implement a covered call strategy in their IRA.
Covered calls may not be as attractive as they seem on the surface, but that doesn’t mean they don’t have a role in your portfolio. Covered calls are ideal for investors seeking portfolio income. Growth oriented investors should take a deep look at the downsides of covered calls to asses their fit within their portfolio. With the right risk mitigation strategies in place, they can effectively generate extra income from your portfolio while reducing downside risk during a bear market or uncertain times.

OptionDash can help streamline many of these steps by crunching the numbers on covered call opportunities. For example, you can easily screen for opportunities and sort them by if-called return, downside protection, and other characteristics. Moreover, you can eliminate high-risk companies and build watchlists to track opportunities over time.
Covered calls may seem like a win-win proposition on the surface – you can generate income while realizing some upside potential. However, the true risk-return profile is a little more nuanced. That said, they’re still a great way to add income to your portfolio, reduce downside risk, or sell positions you already planned on selling.
