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

Intel (INTC) shares plummeted 28.58% on Friday, closing at $65.76, marking one of the company's most significant daily declines in recent memory. Despite beating quarterly earnings expectations, investors were unsettled by the company's more cautious outlook and lingering doubts about its recovery efforts. Trading activity surged, with 447.8 million shares changing hands, more than triple the stock's three-month average of 108.1 million shares.

The S&P 500 (^GSPC) slipped 2.07% to 7,561, while the Nasdaq Composite (^IXIC) fell 2.86% to 25,437. AMD (AMD) and Nvidia (NVDA) also suffered, with AMD shares down 10.88% to $504.80 and Nvidia shares off 4.22% to $204.64, as Intel's warning rippled through the semiconductor sector.

Intel's sharp decline underscores broader concerns about the industry, with investors questioning whether the surge in artificial intelligence demand can justify high valuations and intense capital investments. Although Intel reported robust third-quarter revenue growth, the company's guidance for the fourth quarter fell short, citing sluggish PC demand, manufacturing hurdles, and persistent spending on its turnaround plan.

While Intel's data center and AI division showed strong performance, with revenue surging 78% year-over-year to $7.3 billion, the immediate challenges appear to be more pronounced in weakening demand for PCs, manufacturing roadblocks, and hefty spending on the turnaround. Intel's latest results suggest that the company's data center business remains a bright spot, but the path to sustainable earnings and cash flow remains uncertain.
