The KOSPI index nosedived nearly 17% over just two trading days, wiping out around $620 billion in market value. This plunge came on the back of SK Hynix’s quarterly earnings that, despite a record profit, fell short of what analysts had expected. The result sent shockwaves through the South Korean stock market, particularly hitting tech and AI-related sectors that had been the year's top performers.

SK Hynix’s Earnings Miss Triggers Market Turmoil

SK Hynix reported an operating profit of 60.54 trillion won, a massive 557% rise year-on-year, but still below the 64 trillion won forecast. The semiconductor giant’s shares tumbled 19% across two days, deepening the KOSPI’s slide. Given SK Hynix and Samsung Electronics make up almost half of the index's weight, their setbacks amplified losses across the board. This drop shattered optimism around semiconductor and AI stocks, which had surged on high growth expectations.

Ripple Effects on Investors and Credit Markets

Retail investors, many heavily invested through leveraged ETFs, faced significant losses amid this sudden correction. The volatility forced the South Korean government to hold emergency talks with financial regulators as circuit breakers halted trading multiple times. The bond markets echoed the unease with record widening of credit spreads for cloud computing leaders tied to AI development. All eyes are now on upcoming earnings reports from major tech firms to gauge if the AI investment boom is sustainable or if further pullbacks loom.
