Intel Plunges 29% on Weak Q4 Forecast; Nvidia Slides 4% in Semiconductor Pullback

Historic Single-Day Drop for Intel

Intel (INTC) shares plummeted nearly 29%—marking their worst single-day percentage decline since 1974—after management issued a weaker-than-expected revenue and profit forecast for the fourth quarter.

Spillover Across Chipmakers

• Foundry & PC Headwinds: Slower enterprise PC refresh cycles and heavy foundry turnaround expenses weighed on Intel margins.
• AI Bellwethers Pressured: Even AI GPU leader Nvidia (NVDA) slid over 4% as semiconductor ETFs experienced broad de-risking.

Divergence in Chip Fundamentals

Analysts emphasize a sharp divide between custom AI accelerator demand and legacy x86 data-center CPU sluggishness.

Trading Perspective

Avoid catching falling knives on post-earnings gap-downs; wait for institutional volume stabilization before trading semiconductor reversals.
