Global Chip Stocks Plunge as Memory Makers Lead Broad Sell-Off
Major semiconductor stocks opened lower in premarket trading following a sharp weekly decline, with memory manufacturers and AI-focused firms leading the losses. Micron and SK hynix dropped significantly, while Cerebras and Kioxia fell over 10%. The sell-off coincided with a 6% drop in the South Korean KOSPI index, reflecting broad risk-off sentiment in tech-heavy markets. Despite the downturn, some non-chip tech names like Meta and Salesforce rose, indicating a rotation rather than a total market collapse.
Key points
- Micron Technology fell 3.88% premarket, extending a weekly decline of 5.23%.
- SK hynix dropped 4.02% in premarket, with a full-day loss of 5.15%.
- Cerebras Systems fell 10.69% premarket, with a full-day drop of 11.00%.
- Kioxia Holdings plunged 13.22% in Japanese markets.
- The KOSPI Composite Index fell 5.98%, signaling broad Asian market weakness.
- Meta Platforms rose 3.38% and Salesforce gained 2.09%, showing selective strength in software.
Background
Recent months saw a surge in AI infrastructure spending, with JPMorgan projecting $1.4 trillion in investment by 2030. AMD recently hit a $1 trillion market cap, and Meta's new AI agent boosted CPU demand. This current sell-off follows a period of high valuations and strong growth in AI chipmakers, suggesting a potential correction after a rapid run-up.
Why it matters
The sharp decline in chip stocks, particularly memory makers, signals a potential shift in investor sentiment regarding AI infrastructure costs and supply chain stability. A broad sell-off in semiconductors can ripple through tech sectors, affecting data center buildouts and AI deployment timelines. The divergence between falling chip stocks and rising software names suggests investors may be rotating from hardware to software or de-risking high-valuation tech assets.
What to watch
Investors will watch for further declines in semiconductor indices and memory chip prices. Earnings reports from major chipmakers in the coming weeks will be critical to determine if the sell-off is a correction or a trend reversal. Policy decisions on trade and tariffs may also impact global chip supply chains.
