Growing volatility in South Korean equities has intensified debate over whether single-stock leveraged exchange-traded funds are amplifying market swings. Trading and fund-flow data show heavy turnover and large net buying by retail investors in products tied to Samsung Electronics and SK Hynix, alongside steep losses. Some analysts and industry officials say the actual rebalancing impact is limited and that semiconductor moves, foreign selling and credit supply also matter. They call for stronger investor protections rather than delisting.

South Korea\'s KOSPI closed slightly higher on June 11 after swinging between gains and losses, paring steep early declines. The index opened sharply lower and fell further intraday before recovering to end up 0.43 percent. Retail investors were net buyers, offsetting foreign and institutional selling. The KOSDAQ rebounded 4.76 percent, and the Korea Exchange activated a buy-side sidecar during the rally.
