Korea Stocks Tumble 8% as Investors Rush to Unwind AI Exposure

South Korea's equity benchmark, the KOSPI, plunged nearly 8% in a single session, pushing it into a bear market as a global semiconductor selloff accelerated. Investors are retreating from the frothiest corners of the AI trade, and Korea took the brunt of it.

The scale of the move matters. A near-8% one-day drop is a disorderly repricing, not a routine pullback. Entering bear-market territory means the index has fallen at least 20% from its recent peak, so the damage is already deeper than a single session suggests.

Interpretation: Korea's market is heavily tied to semiconductors, so a chip-led global rout transmits directly into the KOSPI. The move looks like forced de-risking of crowded AI positions rather than a shift in domestic Korean fundamentals, though the source does not detail positioning data.

The key takeaway from the tape is correlation. When investors unwind AI exposure, they do it broadly and fast, and benchmarks with concentrated chip weightings absorb the heaviest losses. Markets elsewhere that carry similar AI-linked weightings face the same contagion risk.
