Individual Investors Net Purchase 1 Trillion Won of Covered Call ETFs Amid Market Volatility
From May 16-22, 'KODEX 200 Covered Call Active' ranked fifth among individual net purchases at 1,037 billion won, while 'TIGER Dividend Covered Call Active' ranked sixth with 965 billion won in inflows, according to KOSCOM ETF CHECK. The 61 domestic covered call ETFs held combined assets of 26.3957 trillion won, an increase of approximately 11 trillion won from the start of the year. The number of available products rose from 52 to 61 during the same period.
The KOSPI fell from 8476.48 to 7096.89 over three weeks, a decline of approximately 1,400 points. The Korea Exchange activated sidecar circuit breakers for five consecutive trading days. Samsung Electronics and SK Hynix experienced significant price swings driven by semiconductor industry concerns and rebalancing demand from single-stock leveraged ETFs, separate from earnings outlooks.
Covered call ETFs hold underlying assets while simultaneously selling call options on those assets, using the option premiums as a source of distribution income. The strategy offers relative stability in sideways or gently declining markets compared to standard index ETFs due to premium income.
Weekly Options and Partial Call-Selling Strategies Address Traditional Upside Limitations
Recent covered call ETF products incorporate weekly options and partial call-selling to address structural weaknesses in earlier designs. Traditional covered call ETFs sold call options on most or all underlying holdings, requiring the fund to surrender upside gains above a certain threshold to option buyers. This structure caused significant underperformance during bull markets.
'TIGER 200 Covered Call,' the longest-running domestic covered call ETF, demonstrated defensive characteristics in 2021, 2022, and 2024 downturns with 16% annualized volatility compared to the KOSPI's 24% — an 8 percentage point difference. However, in strong bull markets the product captured only approximately 26% of KOSPI 200 gains. Higher call-selling ratios directly correlated with reduced upside participation.
Second- and third-generation products use weekly options or sell calls on only a portion of holdings. By writing options on a subset of assets, these ETFs retain premium income while allowing the remainder to capture full upside. Park Woo-yeol, researcher at Shinhan Investment & Securities, stated that first-generation products had high call-selling ratios as their primary weakness, while recent launches use weekly options and adjusted selling ratios to maintain participation during bull markets.
KODEX Semiconductor Target Weekly Covered Call Sells Options on 30% of Assets
'KODEX Semiconductor Target Weekly Covered Call ETF,' listed in May, allocates over 50% to Samsung Electronics and SK Hynix while selling KOSPI 200 weekly options on approximately 30% of assets. The structure avoids selling calls on the entire portfolio, allowing the fund to track equity gains during bull markets while generating premium income during sideways or declining periods.
The partial call-selling approach enables the fund to capture a larger portion of upside compared to full-coverage strategies, while still providing premium-based downside cushioning during volatility. The design reflects industry efforts to balance distribution yield with capital appreciation potential.
PLUS High Dividend Weekly Covered Call Returns -24% YTD Despite High Distribution Rate
Covered call ETFs do not guarantee principal protection. If underlying asset prices decline sharply, ETF prices fall accordingly, and distributions may not offset capital losses.

'RISE 200 High Dividend Covered Call ATM,' which posted the highest one-month return in its category, declined 18.81% over the same period.
Jang Chi-young, researcher at Hana Securities, stated that investors should consider underlying assets, option strategies, and target distribution rates comprehensively when selecting covered call ETFs. Jang identified the call-selling ratio and adjustment methodology as core factors determining the balance between downside protection and upside participation.
