Chip Stocks Slide on China Concerns to Close Strong Month

Semiconductor equities retreated sharply in Friday's session, dragging major U.S. indexes lower amid renewed geopolitical tensions. The PHLX Semiconductor Index fell 3% as market leaders Nvidia and Broadcom led declines, with Marvell Technology plunging 20% after disappointing guidance.

Washington's MOVE to restrict chipmaking equipment exports to Chinese facilities operated by Samsung and SK Hynix exacerbated sector-wide pressures. The policy shift threatens to disrupt global semiconductor supply chains already grappling with bifurcated U.S.-China tech ecosystems.

August's pullback arrives after a robust performance for chip stocks, highlighting the sector's sensitivity to geopolitical crosscurrents. Market participants now weigh the durability of AI-driven demand against escalating trade restrictions.
