Overview
On June 23, 2026, the Kospi index suffered its steepest single-day drop in years, triggered by heavy profit-taking from foreign investors and the market’s concentrated exposure to the chip sector. SK Hynix, a major supplier of high-bandwidth memory chips for AI, had become the symbol of this AI-driven rally after a long surge in its stock price. However, the intense focus on chips led to short-term side effects, as SK Hynix’s sharp decline amplified the market’s fall. This episode highlighted how concentrated bets and speculative enthusiasm can quickly turn into widespread volatility.
