The Wall Street Journal recently warned that Korean market volatility is being amplified by leveraged products tied to Samsung Electronics and SK Hynix, stating:

“When the party ends, most of the losses will likely be borne by domestic retail investors.”

Over the past month, the KOSPI has experienced daily swings of approximately 5%, with analysts attributing much of the volatility to leveraged ETFs and derivatives concentrated on these two semiconductor giants. The situation raises concerns about systemic risk for domestic individual investors.
