China chip tool breakthrough and AI slowdown fears hit ASM
China's own chipmaking tools threaten demand China began mass-producing its own deep ultraviolet chipmaking equipment, the machines that make advanced chips. If Chinese chipmakers buy local tools instead of Western ones, they need less of ASM's deposition equipment, so investors sold the stock hard.
This is the biggest new force behind the drop, directly hitting ASM's future sales.
AI leaders call for slower development Top AI figures including Anthropic's Dario Amodei and OpenAI's Sam Altman urged a slower pace of AI development. That clouds the outlook for AI-driven chip equipment demand, and ASM fell 8.7% as investors questioned how fast AI spending will keep growing.
A fresh, separate worry about ASM's end-market demand that drove a sharp sell-off.
Sector-wide tech sell-off drags ASM down Even with a positive earnings outlook, ASM dropped 4.8% as European tech stocks fell for a third straight day. When the whole sector is sold, strong company news is not enough to hold the share price up.
Shows ASM's price is being pulled by broad sector weakness, not just its own results.
