- Asian tech heavyweight stocks are under pressure across the board, with South Korea's benchmark index triggering a circuit breaker during trading. The sell-off in U.S. chip stocks and concerns over AI capital expenditure benefits have heightened regional risk aversion significantly.
- Rumors of Nvidia's massive financing commitment and breakthroughs in domestic lithography machines have led to a market reassessment of AI infrastructure returns and the competitive landscape of semiconductor equipment, resulting in a widespread valuation adjustment across related industries.
- Mainland China and Hong Kong markets have shown strong resilience, buoyed by expectations of self-reliance, as global macro focus shifts to the interest rate meetings of the Federal Reserve and other major central banks, as well as tech giant earnings reports.
Chip Heavyweights Plunge, Triggering Circuit Breaker in Korean Market
Amid rising global tech stock risk aversion, South Korea's benchmark KOSPI index saw its intraday decline expand to over 9%, triggering both sidecar and circuit breaker mechanisms. Major memory chipmakers SK Hynix (KS:000660) and Samsung Electronics (KS:005930) experienced significant pullbacks, reflecting market participants locking in profits ahead of major earnings reports. Japan's Nikkei 225 and TOPIX indices also fell in tandem, with concentrated selling of heavyweight tech stocks suppressing short-term market risk appetite.
Capital Expenditure Concerns Intensify, Semiconductor Equipment Under Pressure
Last week's discussions on Nvidia's (NVDA:US) financing scale and infrastructure return rates have further exacerbated concerns about over-leveraging in the AI industry chain. Meanwhile, expectations of changes in the competitive landscape have pressured the semiconductor equipment sector, with significant declines in Kioxia Holdings (285A:JP) and Tokyo Electron (8035:JP), and valuation correction pressures on industry leaders like ASML (ASML:NA), indicating a rapidly decreasing tolerance for high valuations in the tech sector.
Self-Reliance Boosts Confidence, Resilience in Hong Kong Tech Stocks
Compared to the volatile markets in Japan and South Korea, mainland China and Hong Kong stock markets have shown strong defensive attributes, with the Hang Seng Index closing slightly higher. Changxin Memory's strong debut in the Shanghai market, coupled with expectations of breakthroughs in domestic lithography technology, has effectively boosted confidence in the domestic substitution theme. Internet tech giants like Meituan (03690:HK) and Alibaba (09988:HK) saw buying interest on dips, supporting overall liquidity in the regional market.
Major Macro Rate Decisions Loom, Funds Shift to Defensive Stance
Crude oil futures continue their downward trend, with signs of easing tensions between the U.S. and Iran partially alleviating short-term inflation risks, but failing to offset the impact of tech stock pullbacks on macro sentiment. As the Federal Reserve, Bank of Japan, and Bank of England announce their rate decisions this week, along with upcoming earnings reports from tech giants like Microsoft and Apple, global funds are becoming more cautious, with market pricing aligning towards dual validation of interest rate paths and fundamental outcomes.
