The Great Korean AI Bubble: When 10% of the Stock Market Vanished in One Day
Leveraged ETF trading is fantastic when semiconductor stocks go to the moon. But when they dip, your portfolio turns into a black hole faster than an AI image generator produces a hallucination.
On July 28, 2026, South Korea's stock market experienced a historic meltdown. The KOSPI index plunged 10.84% in a single day—the largest single-day drop in Korean market history—triggering a 20-minute emergency circuit breaker freeze as trillions of won evaporated.
The Revenge of Leveraged Ants
The culprit? A deadly combination of AI hype, concentrated memory chip stocks (Samsung & SK Hynix), and retail investors buying into 2x and 3x leveraged single-stock ETFs. When international markets wobbled, algorithmic margin calls triggered a domino effect of panic selling.
📉 KOSPI Crash Stats:
1. Single-day drop: -10.84%.
2. Circuit breaker trading freeze: 20 minutes.
3. Retail investor stress levels: Off the charts.
