KOSPI Volatility Doubles Since Single-Stock Leveraged ETF Listing on May 27

According to financial investment industry sources, South Korea's KOSPI index has seen volatility nearly double since 14 single-stock leveraged and inverse ETFs launched on May 27. Over 31 trading days following the listing, daily average fluctuations reached 288.81 points, up from 150.51 points in the prior 31-day period, while the daily change rate rose to 3.49% from 2.15%.

The V-KOSPI volatility index climbed to 84.54 from 57.70 over the same period. Industry analysts attribute the surge to concentration in Samsung Electronics and SK Hynix, which account for a significant KOSPI weighting. The 14 new products generated 361.4 trillion won in trading volume, representing 30.5% of total ETF trading and 13.2% of overall KOSPI trading, amplifying market swings through short-gamma rebalancing mechanics that accentuate price moves.
