Stock Market Today, Oct. 30: Intel Plunges Nearly 29% as Weak Outlook Rattles Wall Street

Intel shares plummeted 28.58% on Friday despite beating Q3 earnings expectations, driven by disappointing Q4 guidance citing weakening PC demand and manufacturing constraints. The sell-off rippled through the semiconductor sector, with AMD and Nvidia also declining. However, Intel's Data Center and AI division showed strength with 78% year-over-year revenue growth, suggesting challenges are concentrated in PC markets rather than data center demand.
