Retail investors across South Korea are facing a brutal awakening after aggressive bets on the nation’s artificial intelligence powerhouses turned sour. For months, many traded heavily in leveraged exchange traded funds tied to semiconductor giants Samsung Electronics and SK Hynix, hoping to multiply their gains as the AI boom pushed chip stocks higher. However, a sharp market reversal has left these speculators nursing deep wounds, turning what felt like easy money into a financial nightmare for thousands of households.
The scale of the gamble was immense. Since late May, domestic retail investors poured roughly 14 trillion won into single stock leveraged ETFs, dwarfing the interest shown by foreign players. This appetite for risk proved costly when the tide turned. The KODEX SK Hynix Single Stock Leverage ETF, designed to double the daily movement of the company’s shares, has plummeted approximately 70 percent from its June peak. On online trading forums, the mood has shifted from exuberance to desperation, with some users pleading for their lost capital and others claiming the market is actively trying to destroy them.
This wave of losses is not limited to novice traders following social media trends. Experts note that many of those hit hardest are experienced investors in their 40s and 50s who became overly comfortable with concentrated technology positions and margin borrowing. The Bank of Korea recently flagged this trend as a growing concern, noting that while it might not threaten the entire financial system, such extreme leverage inevitably amplifies volatility during any correction. When fear of missing out drives people to borrow money to chase a rally, the crash becomes far more painful.
In response to the carnage, regulators have stepped in to cool the fever. New rules now require investors to hold at least 30 million won in cash to trade single stock leveraged ETFs, a tenfold increase from previous requirements meant to keep speculative retail gambling in check. While some analysts believe the long term prospects for memory chips remain sound, others warn that semiconductors have become too crowded a trade globally and that we may be seeing just the beginning of a wider retreat from the sector.
