Single-stock leveraged ETFs in South Korea reached 5.1 trillion won in market capitalization within one month of listing, with the KODEX SK Hynix Single Stock Leverage product leading the surge. The combined market cap of SK Hynix leverage products in South Korea totaled approximately 9 trillion won, surpassing the US NVDL (Nvidia leverage ETF) at 6 trillion won, despite SK Hynix's market cap being four times smaller than Nvidia's. The rapid growth of these 14 listed products triggered 13 sidecar events (program trading halts) on the KOSPI since May 27, accounting for half of the 31 sidecars activated in 2026, as concentrated leverage trading amplified volatility in semiconductor stocks. Individual investors shifted from net buying 3 trillion won in KOSDAQ during May to net selling 2.8 trillion won after leverage product launches, redirecting capital into leveraged bets. South Korea's leverage ETF boom reflects disproportionately intense speculative activity compared to global markets, with retail traders facing mounting losses from negative compounding effects inherent in daily-rebalanced products.
Leveraged ETFs Concentrate Trading Activity in South Korean Stocks Market
On May 3, when the KOSPI rose 6.53%, single-stock ETFs occupied the 3rd through 5th positions in trading volume rankings. Currently, 105 stocks on KOSPI and 11 on KOSDAQ have larger market caps than the 5.1 trillion won KODEX SK Hynix Single Stock Leverage ETF. The scale of individual investor purchases in leveraged products prevented buying momentum from spreading to other stocks, instead promoting selling activity across the broader market.
Samsung Securities Research Center analysis showed SK Hynix's end-of-day trading volume increased from an average of 390,000 shares before leverage product launch to 650,000 shares after launch, a 65% increase. Jeon Gyun, researcher at Samsung Securities, stated that trading volume distribution by time period showed significant increases in the latter half of trading sessions, particularly at market close, resulting from the combination of rebalancing volume from leveraged products and short-term trading intensified by sharp price movements.
Sidecar Triggers Surge as Leverage Products Amplify Volatility
Since May 27, the KOSPI experienced 13 sidecar activations despite stabilized global markets following eased geopolitical tensions from Iran-related events. This represented half of the 31 sidecars triggered in 2026. The concentration of market capitalization in semiconductor leaders combined with single-stock leverage products amplified volatility in semiconductor stocks.
Cho Chang-min, researcher at Hyundai Motor Securities, explained that in past crisis periods, volatility in semiconductor and non-semiconductor stocks moved together, but leverage products now concentrate volatility in a small number of leading stocks. The effect intensified during sharp declines led by foreign net selling. Foreign investors frequently hedged by purchasing futures in bulk at the end of trading sessions during excessive declines, profiting from market normalization the following day after leverage ETFs amplified the initial selloff.
Samsung Electronics Stocks Leverage ETF Records 10.75% Loss Despite Underlying Gain
From listing through May 3, Samsung Electronics rose 0.81% while the KODEX Samsung Electronics Single Stock Leverage ETF fell 10.75%. Under the product structure, a 0.81% gain in the underlying stock should produce a 1.62% gain in the leveraged ETF, but negative compounding effects resulted in the 10.75% decline. Similarly, SK Hynix rose 8.11% while the KODEX SK Hynix Single Stock Leverage ETF fell 1.35% during the same period.
Asset management companies advised at launch that investors should not hold these products for more than one week and should maintain only short-term positions due to negative compounding effects that increase with holding period. However, many investors who bought leveraged ETFs during price declines failed to cut losses and became long-term holders, expanding their losses.
Korea Investment & Securities analysis of customer accounts showed the average holding period for single-stock leverage products was 15-17 days. Given that only 37 days passed since launch, this indicates many investors hold positions while betting on semiconductor industry trends rather than executing short-term trades.
Investors with assets under 30 million won allocated 21% of their assets to the KODEX SK Hynix Single Stock Leverage product, while investors with assets over 1 billion won allocated 9%, according to Korea Investment & Securities. Demand for leveraged ETFs increased as securities firms reached credit limits during the market boom, making new margin trading difficult. A private banking center employee at a securities firm stated that wealthy investors understand leveraged ETFs carry high loss potential from negative compounding effects and have access to multiple borrowing options, leading them to invest in underlying stocks or semiconductor ETFs using other loans rather than purchasing leveraged ETFs.
