AMD Is Down 20% in a Month. Is It Cheap After the Drop, or Still Expensive?
AMD stock lost 11% in a single day, even though its biggest customers promised that same week to spend even more on AI. The trigger was Intel and the PC market. But hidden inside its warning is a threat that will hit AMD somewhere else entirely.
Key points
AMD fell 10.9% in a single day, almost four times faster than the Nasdaq, and the trigger didn’t come from AMD
Amazon and Alphabet both promised to spend more on AI that same week, yet the market sent their suppliers lower anyway
Intel’s worst day since 1974 contains a warning that affects AMD not in PCs, but elsewhere
Lisa Su talks about “very good visibility” into 2027, but adds a caveat in the very next sentence
Analysts’ consensus target is 605 USD, and results are due Tuesday after the close
A Friday that made no sense
Advanced Micro Devices $AMD closed Friday, October 30, at 504.80 USD, down 10.9% from the previous day. That’s a roughly 22% drop from its record close above 649 dollars on October 6, and the stock has lost 20.4% in a month. Yet it is still up 135.7% year to date, and up 368% over three years. A reader who has held it since last year is still richer than someone who held the index. Just a lot less rich than four weeks ago.
AMD wasn’t alone. The Nasdaq had its worst day since June and closed October down 5.2%, its worst month since March 2025. But AMD fell almost four times faster than the index and more than twice as fast as Nvidia $NVDA (-4.2%) or Broadcom $AVGO (-5.5%).
The trigger didn’t come from AMD. It came from Intel and concerned personal computers—a part of AMD’s business that matters least to its valuation. So the fastest-growing large chipmaker took its hardest hit over something that isn’t the foundation of its investment story.
So why did the market do it?
