Global chipmakers sink as inflation data fuels rate-hike fears, AI rout

Global semiconductor stocks fell sharply Thursday, with SK Hynix, Micron, Nvidia, Intel, and AMD among the decliners. European chipmakers like Infineon, ASML, and STMicroelectronics also dropped. The sell-off was driven by U.S. inflation data, which fueled fears of further Fed rate hikes. U.S. consumer prices rose 0.6% in September, with annual inflation at 3.7%.
