South Korea's stock market took a heavy hit as investors rushed to exit bets tied to artificial intelligence. According to BNN Bloomberg and AP News, the benchmark Kospi index dropped 4.5% — nearly 5% — as traders unloaded shares of companies linked to AI.
Much of the pain traces back to leveraged positions. According to The Standard (HK), the market's losses deepened as heavily leveraged AI bets took a toll. Leverage means investors borrowed money to amplify their wagers; when those stocks fall, the losses are magnified and can force rapid selling, which in turn drives prices down further.
The selloff coincided with a shift in sentiment from Wall Street. According to a report carried by MSN, Citigroup downgraded South Korea to "neutral" after a year-long "overweight" stance — effectively cooling its recommendation to own the country's stocks. The bank cited heightened volatility in AI-linked chip stocks and what it called stretched valuations, meaning prices had climbed high relative to underlying earnings.
The turbulence was not uniform across markets. AP News reported that world shares were mixed and Asian shares mostly higher, even as the Kospi slumped and oil prices kept climbing. Fat Tail Daily grouped the episode with a broader wobble hitting both commodities and AI-linked names.
South Korea's market is unusually exposed here because it is home to major semiconductor makers whose chips power the AI boom, making the Kospi a bellwether for global AI enthusiasm.
Why it matters: the sharp, leverage-driven drop is an early warning sign that the market's appetite for AI-related stocks may be turning, and that stretched valuations can reverse quickly when confidence cracks.
