SK Hynix and Samsung Electronics single-stock leveraged and inverse exchange-traded funds recorded losses exceeding 40% between May 27 and the 15th, significantly outpacing the underlying stocks' declines of 7.2% and 9.0% respectively. The outsized losses stem from the ETFs' daily reset structure, which causes negative compounding effects during periods of high volatility as daily returns recalculate from new baseline prices each trading session. South Korean government officials announced plans to introduce regulatory improvements for single-stock ETFs, with Financial Services Commission Chairman Lee Eok-won stating that comprehensive measures addressing market volatility and investor protection will be released soon.

Inverse ETFs Lose Over 40% Despite Correct Directional Bets
SOL SK Hynix Futures Single Stock Inverse 2X fell 43.84% during the same period, despite SK Hynix stock declining. The inverse ETF was designed to profit from SK Hynix declines but generated losses larger than the corresponding leveraged products.
PLUS Samsung Electronics Futures Single Stock Inverse 2X declined 21.30% while Samsung Electronics stock fell approximately 9%. Simple calculations would suggest an 18% gain for a 2x inverse product tracking a 9% decline, but actual performance showed losses instead.
Daily Reset Structure Causes Negative Compounding in Volatile Markets
Single-stock leveraged and inverse ETFs do not track cumulative returns over extended periods at 2x magnification. Instead, these products reset daily to track 2x the underlying asset's daily return, recalculating from a new baseline price each trading session.
When stocks move in one direction consistently, divergence from the underlying asset remains limited. However, in volatile markets with repeated up-and-down swings, daily returns compound from continuously changing reference prices. This structural characteristic, termed "negative compounding," becomes more pronounced in stocks like SK Hynix and Samsung Electronics that experienced large intraday fluctuations.
