Summary · why it matters

Semiconductor stocks tumbled globally after a report that South Korea's SK Hynix is slowing its high-bandwidth memory expansion, triggering a broad sell-off in the AI-chip complex. SK Hynix and Samsung each dropped more than 12% in Asia, dragging the KOSPI down about 10% and activating a 20-minute market-wide circuit breaker, while European names like ASML fell 5% and the Philadelphia Semiconductor Index opened roughly 7% lower a day after a record close. The move reflects a margin story rather than a demand story, as SK Hynix is redirecting capacity into conventional DRAM where shortages have pushed operating margins more than 15 points above HBM's, according to Korean analysts. Among U.S. stocks, Applied Materials fell 8.3%, Teradyne fell 8.3%, and Entegris fell 9.4%, with memory names bearing the brunt as Micron dropped 11% while logic-heavy Nvidia fell only about 3.6%. Wedbush framed the drop as a buying opportunity with enterprise demand intact.
