Why Is Arm Holdings $ARM Stock Down -7.99% Today? (Find out why any stock moved today on Tickeron.) • Arm Holdings $ARM shares fell 7.99% to $285.54 in early trading Monday, retreating from a prior close of $310.32. • The decline was driven primarily by a broad selloff across semiconductor and AI-infrastructure names, not by company-specific news. • Concerns over the pace of AI data-center buildouts resurfaced after reports that Oracle issued a force-majeure notice tied to a New Mexico data-center project, weighing on the AI-capex trade. • The Philadelphia Semiconductor Index dropped roughly 4.7%, with peers including Intel, AMD, Micron and Nvidia all trading lower. • ARM's premium valuation made it more vulnerable to the sector-wide de-risking, amplifying its losses relative to peers. • Traders are watching whether the AI-infrastructure weakness spreads and how semiconductor indices close the session. $QCOM $AVGO $MRVL $MU $AMD $INTC $ALAB
