Japanese and South Korean stock markets plunged sharply in early Tuesday trading, with the Nikkei 225 down over 4% and the KOSPI index tumbling 8%, triggering a circuit breaker. The sell-off was led by semiconductor and equipment stocks like Tokyo Electron, Kioxia, Samsung Electronics, and SK Hynix, the latter dropping as much as 30%. The primary driver is mounting investor concern over the sustainability of the AI boom. Worries intensified following news related to Nvidia's major AI supply agreements and rising debt insurance costs. Analysts point to fears over excessive capital expenditure, crowded trades in AI-related stocks, and high corporate debt levels. Market sentiment has soured ahead of key earnings reports from major tech firms, including Meta and SK Hynix. While SK Hynix is expected to post record results, its recent 38% price drop from June highs reflects deep skepticism about whether AI infrastructure spending can maintain its pace and deliver returns. The sell-off appears more driven by a sharp deterioration in sentiment than by immediate fundamental changes.
