Why Is Arm Holdings (ARM) Stock Up 5.18% Today, Oct 2? Softer Jobs Data and Semiconductor Rally Lift Shares

Softer-than-expected U.S. payrolls reduced perceived near-term Fed hike risk, supporting valuation-sensitive tech and driving a broad semiconductor rally. Arm's +5.18% move reflects sector beta and persistent AI-infrastructure optimism rather than idiosyncratic news, with traders focused on whether the post-macro bid sustains. The setup implies tighter linkage between rates expectations and chip risk appetite in the near term.
