"Invested 10 Million Won, Received 1 Million Won in Distributions, But Why?"... Don't Be Misled by the Numbers [Practical Asset Management]

Covered Call ETF Volatility Requires Caution in Stock Markets
Weaknesses in Sharp Rallies and Market Plunges
Understand Unique Structures Like Return of Capital
Focus on Total Investment Return Over Simple Monthly Distribution Rate

Mr. A heard that covered call exchange-traded funds (ETFs) had become popular, so he purchased a product with a 10% annual distribution rate for 10 million won. Over the following year, he received 1 million won in distribution payments. However, due to the nature of covered call products—which cap upside returns during a rebound after a drop in the ETF’s underlying assets—he did not recover his initial principal, and the ETF price fell to 8.5 million won. Ultimately, what was Mr. A’s account performance? Adding the current price of 8.5 million won to the 1 million won in distributions, his final amount was 9.5 million won. Although he received 1 million won in cash, his overall account suffered a loss of 500,000 won (-5%).

As volatility in the Korean stock market intensifies, covered call ETFs—offering both stable cash flows and downside protection—are emerging as an alternative for dividend-focused investors. However, experts caution that investors must thoroughly understand the unique structure of covered call ETFs, which differ from standard ETFs. In particular, since principal losses are possible, one should not invest based solely on the distribution rate figures.

Covered call ETFs generate profit and loss depending on changes in their underlying assets. These ETFs retain a portfolio of stocks while selling call options (the right to buy at an agreed-upon price), thus receiving premiums (option sale proceeds). For example, if a product uses the KOSPI index (such as KOSPI200) as its underlying asset, the collected option premiums can partially offset losses during sideways or mildly declining markets, providing a steady monthly distribution.

However, there are disadvantages during significant upswings or sharp declines. If the underlying asset price surges past the strike price, gains are capped due to the structure of selling call options. On the other hand, losses are not capped on the downside; if the underlying asset drops beyond the amount covered by the option premiums, the ETF’s principal can also plunge sharply. For instance, a covered call ETF based on the KOSDAQ150 is more volatile than those based on the KOSPI or the U.S. S&P 500. Due to the characteristics of options, higher volatility leads to higher premiums, which can make the displayed distribution rate appear attractive. However, in a crash, the downside risk is uncapped and principal can be eroded, while in a sudden rebound, the capped upside may mean missing the opportunity to recover principal.

Monthly distributions from covered call ETFs can include not only option premiums and dividends, but also trading profits and capital return (principal repayment) components. Capital return occurs when an ETF’s actual net operating profits—from option premiums and other sources—fall short of the target distribution rate, prompting the fund to return part of the investor’s principal (NAV) as a distribution. Therefore, relying solely on the displayed distribution rate may not provide an accurate picture of actual investment performance. In covered call ETFs using daily expiring call options—known as daily-target covered calls—if the underlying asset is, for example, the U.S. Nasdaq index, then even if the index recovers after repeated sharp drops, the ETF’s NAV may gradually decline, and capital return may accumulate as the fund reduces its principal to meet its target distribution rate.

As a result, investment performance should be evaluated by considering total investment returns, including fluctuations in asset value. It is also essential to check the distribution calculation method and the sources of distribution. Suyeon Sim, Senior Research Fellow at the Korea Capital Market Institute, noted that the method for calculating distribution rates can differ across domestic covered call ETFs, adding, “From an investor’s point of view, it is necessary to take a comprehensive approach—comparing not just product names or monthly distribution rates, but also underlying assets, option management methods, sources of distribution, total investment return, expenses, and post-tax performance.”
