South Korea\'s KOSPI rebounded after nearly a 9 percent drop a day earlier, supported by bargain buying from foreign investors and institutions. The index finished up 0.73 percent at 6,856.83 after opening lower and briefly rising to the 6,900 level. The KOSDAQ fell 1.92 percent to 783.98 and failed to regain 800 after a sell sidecar was triggered during the session.

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.
