South Korean retail investors holding Samsung and SK Hynix leveraged ETFs are facing heavy losses following a sharp reversal in technology stocks. The single-stock leveraged exchange-traded funds were introduced on May 27, after which Korean individual investors purchased a net 14 trillion won, equivalent to approximately $9.4 billion, according to KB Financial Group. The products amplify the daily percentage movements of South Korea's two largest chipmakers, but the quick decline in semiconductor shares caused significant damage as leveraged ETFs reset their exposure every day, resulting in losses larger than initially expected during prolonged volatility. South Korean regulators responded by introducing stricter requirements, mandating investors maintain at least 30 million won in cash to trade these products, compared with an effective previous minimum of approximately 3 million won.
KODEX SK Hynix Leverage ETF Falls 70% From June High
The KODEX SK Hynix Single Stock Leverage ETF, designed to generate twice the daily percentage movement of SK Hynix shares, has fallen by almost 70% from the record high it reached in June. The fund is also down roughly 50% from its launch price. Because leveraged ETFs reset their exposure every day, prolonged volatility and repeated declines resulted in losses bigger than investors initially expected.
Retail demand for these products surged after the May 27 launch. The strategy initially looked attractive as Samsung Electronics and SK Hynix benefited from strong investor enthusiasm around artificial intelligence, memory chips and data-centre demand. However, the steep drop caused frustration in South Korean online trading forums, particularly after SK Hynix suffered its largest one-day decline on record. Investors posted emotional messages describing severe financial losses and regretting their decision to enter the stock market.
Korean Retail Investors in 40s and 50s Carry Most Losses
Domestic retail traders have carried most of the losses. Jung In Yun, founder of Fibonacci Asset Management, said the affected investors are overwhelmingly South Korean individuals. He added that many buyers are not inexperienced young traders, but investors in their 40s and 50s who have become comfortable using leverage and making concentrated bets on technology stocks.
Leveraged products have become a much larger part of the South Korean market. Assets held by the 25 largest leveraged Korea-focused ETFs accounted for approximately 30% of the category by June, up from about 15% at the beginning of 2026, according to Oxford Economics. The Bank of Korea warned that leveraged stock investment among retail traders has reached a record high. Much of the increase has been driven by margin borrowing and concentrated positions in semiconductor companies. Although the central bank does not currently view the situation as a systemic risk, it said leverage could intensify market volatility during corrections.
Regulators Raise Minimum Trading Requirement to 30 Million Won
South Korean regulators introduced stricter requirements for Samsung SK Hynix leveraged ETFs and similar single-stock products. Investors will be required to maintain at least 30 million won in cash to trade them, compared with an effective previous minimum of approximately 3 million won.
