South Korea's Financial Services Commission (FSC) is set to unveil a supplementary plan for single-stock leveraged ETFs, including those of Samsung Electronics and SK Hynix, amid concerns over market volatility. Chairman Lee Yiyuan stated that regulatory authorities are assessing the impact of these products on market fluctuations and are working on a comprehensive strategy. The plan aims to address the volatility attributed to the global semiconductor industry's super cycle and the significant influence of Samsung and SK Hynix on the Korea Composite Stock Price Index (KOSPI).
