On October 7, the office of a South Korean lawmaker revealed that individual investors had suffered an estimated loss of KRW 2.3 trillion (approximately $1.7 billion) over a span of several months. These losses stemmed from investments in leveraged exchange-traded products that tracked the performance of South Korea's two leading chipmakers—Samsung Electronics and SK Hynix. This marked the first public disclosure of the magnitude of risk associated with such investments. According to the office of Choi Eun-hee, a lawmaker from the opposition "People Power Party," clients of 10 South Korean brokerage firms incurred these losses between May 27 and August 14 by investing in single-stock ETFs and related notes linked to these two chipmakers. These single-stock products, which were introduced in May, have significantly heightened the volatility of the AI-driven stock market in South Korea. Previously, leveraged bets had propelled the South Korean stock market to rank among the top-performing markets globally. However, a subsequent market downturn led to dire consequences. The pronounced volatility triggered by these high-risk products prompted regulatory intervention to dampen retail investor enthusiasm, resulting in a notable decrease in trading volumes.
