GoKawiilIntel shares fall 45% in October after weak PC outlook and guidance miss
Intel's stock suffered its worst monthly drop on record in October, down 45%, after the company warned quarterly revenue could fall $1 billion to $2 billion short of analyst estimates. CEO Lip-Bu Tan cited a weakening PC market, with rising memory and component costs discouraging consumer upgrades, while Intel's foundry business still lacks a marquee external customer for its most advanced chips. The stock fell another 8% on Monday following a 29% single-day drop, its worst since the 1970s.
GoKawiil's interpretation of the reporting above, not reported fact.
The selloff reverses months of optimism built on the U.S. government's 10% stake and Nvidia's $5 billion investment, which had driven the stock up sixfold before June. Investors appear to be questioning whether Intel's manufacturing turnaround can succeed while its core PC business, still roughly half its revenue, continues to weaken. The pressure could intensify scrutiny of Tan's forecast that server processor demand will grow fivefold over five years, since that projection has yet to translate into committed foundry customers.
- Intel stock fell 45% in October, its steepest monthly drop on record.
- Revenue guidance missed estimates by $1-2 billion amid a weak PC market.
- Intel's foundry unit still lacks a major external customer despite $108 billion in capex.
