The Hidden Force Behind South Korea’s AI Stock Market Crash | AB Explained

The South Korean stock market’s recent AI-driven rally and subsequent crash reveal a complex interplay between institutional capital and retail investors, rather than a simple bubble fueled by individual greed. While global media often blames "ants"—ordinary retail investors—for inflating the market, data shows that foreign institutional investors were the primary drivers of the initial surge and the subsequent massive sell-off. Structural issues, including the "Korea discount" and government-led corporate governance reforms, incentivized institutional activity, while the late-stage introduction of single-stock leveraged ETFs trapped retail investors in a volatile, high-stakes environment. Ultimately, the market’s trajectory was dictated by institutional risk management and global portfolio rebalancing, with retail investors frequently absorbing the impact of these large-scale capital shifts. This situation highlights how institutional liquidity and sophisticated strategies dominate market movements, leaving individual investors vulnerable to systemic volatility.
