The Intel stock crash has turned into a sector-wide sell-off. Intel shares fell nearly 29% on October 30, 2026, their worst day since 1974, after a disappointing fourth-quarter forecast. They dropped about 9% more on November 2. According to Yahoo Finance, chip and memory stocks have lost about $3.7 trillion in market value since October 6.

What triggered the Intel stock crash
The surprise was not the last quarter. It was the outlook. Intel's Q3 2026 results were strong, but its Q4 forecast came in lower.
| Metric | Q3 2026 (actual) | Q4 2026 (guidance) |
|---|---|---|
| Revenue | $16.5B, up 21% year on year | $15.0B to $16.0B |
| Non-GAAP gross margin | 44.1% | 38.0% |
| Non-GAAP EPS | $0.52 | $0.25 |
Lower revenue, a margin drop of about six points and EPS cut by more than half spooked investors. CFO David Zinsner also said he sees "the PC slowdown continuing at least through the first half of next year."
Strong AI data centre growth was not enough
Intel's Data Center and AI revenue jumped 78% to $7.3 billion. Its foundry business grew 58% but still lost $1.9 billion. The PC chip unit, its largest, shrank 5%. Investors focused on the weaker PC outlook and the falling margins.
How the sell-off spread
Yahoo Finance reports these moves since October 6:
| Company | Market value lost |
|---|---|
| Nvidia | About $896 billion (about −16%) |
| TSMC | About $435 billion |
| AMD | About $298 billion |
| Intel | About $279 billion (about −47%) |
On November 2 alone, chip stocks lost more than $400 billion while about 7 in 10 S&P 500 stocks rose. Micron, Sandisk, Seagate and Western Digital each fell about 6% to 8%. Marvell fell more sharply after agreeing to buy Lumentum.
Why investors are selling chips
- Weak PC demand, which Intel expects to last into 2027.
- Rising memory and manufacturing costs squeezing margins.
- Doubts about AI spending turning into profits quickly enough.
- Rate worries, with markets pricing a likely Fed hike in December.
Is it a buying opportunity?
Views are split. Adam Johnson of Bullseye Brief told Yahoo Finance "The market kitchen-sinked it", meaning the worst may be priced in. Former Cisco CEO John Chambers warned "There will be major train wrecks", though he added "I would not bet against Nvidia." Yahoo Finance also found that chips rose in all eight midterm cycles since 1994, measured from the last October close to the next June. In 2002 and 2018, though, they first fell about 11% more. Past patterns do not guarantee future returns.
What to watch next
- AMD earnings on Tuesday, November 3, after the close.
- Qualcomm earnings on Wednesday, November 4, after the close.
- The October jobs report on Friday, November 6, which shapes Fed hike odds.
