AI Bets Warp Korea's Stock Market
20 Jul
Summary
- Over half of South Korean stock circuit breakers occurred recently.
- Leveraged single-stock funds are driving market volatility.
- Chipmakers Samsung and SK Hynix dominate KOSPI index.
South Korea's stock market, once a reliable barometer of global growth, has become highly volatile. This shift is attributed to billions of dollars in leveraged bets concentrated on artificial intelligence-focused companies, particularly chipmakers Samsung Electronics and SK Hynix. These companies now constitute over half of the benchmark KOSPI index.
Recent trading activity has seen a dramatic surge in circuit breakers, with more than half of all historical instances occurring in the last six months. This volatility suggests the market has detached from traditional economic fundamentals. Price-to-earnings ratios for key players have fallen below five, indicating a disconnect from future earnings potential.
The primary drivers of current stock prices are capital flows from an explosion in single-stock leveraged funds. Assets in a Hong Kong-listed twice-levered SK Hynix fund have grown over twentyfold this year to $7.78 billion. This concentration of bets, fueled by approximately $23 billion in margin loans by retail investors, has led to extreme price swings, even influencing Wall Street.
