Semiconductor Stocks Slide as Supply Bottlenecks Squeeze Equipment Forecasts

Original summary · What happened

Shares across the semiconductor sector dropped on Thursday following warnings of persistent supply chain bottlenecks from equipment supplier Lam Research. Lam Research shares sank as much as 10% after leadership indicated that near-term logistics and procurement constraints capped its forward financial projections, adding that sales into China are positioned to weaken materially heading into December. The PHLX Semiconductor Index declined about 3% to 4%, reversing previous recovery attempts and bringing total market value losses across the chip space to roughly $2.7 trillion since early October.

The decline extended across multiple hardware categories, pulling down major chip developers including Nvidia, AMD, and Intel, along with wafer fabrication supplier Applied Materials. Memory specialists Micron Technology and SK Hynix also encountered sustained selling pressure despite commentary from Nvidia leadership pushing back against fears of a long-term memory surplus. Broader market sentiment around the artificial intelligence build-out has softened as investors assess elevated infrastructure spending commitments against capital availability constraints and macroeconomic pressures.
