The chip stocks selloff on 30 October pushed the Philadelphia Semiconductor Index down 7.2% in one day, and Intel’s weak outlook lit the fuse. Intel fell nearly 29%, AMD lost almost 11%, and Nvidia, Broadcom and Micron also dropped. But the companies face different problems, so one headline hides three stories. This guide separates them and shows which tests arrive this week.
Key takeaways
- What: the chip stocks selloff took the semiconductor index down 7.20% on 30 October, its biggest one-day drop since 5 June, per TradingKey.
- Trigger: Intel guided Q4 revenue to $15 billion to $16 billion, against $17.07 billion expected.
- Second blow: Amazon’s results and its roughly $220 billion 2026 capital spending plan renewed doubts about AI returns.
- Different problems: Intel is about PC demand and supply, AMD about PC plus AI, Micron about memory pricing.
- Status: already out since 30 October. This chip stocks selloff explainer is not a scoop.

How big was the chip stocks selloff?
The table shows the chip stocks selloff by company, comparing regular-session closes on 30 October with 29 October, per INDmoney, which cross-checked the prices against other records. Intraday figures vary by source: Intel was reported down about 30% at the open and 29% elsewhere, while the closing figure was 28.58%.
| Company | 30 Oct close | One-day change |
|---|---|---|
| Nvidia (NVDA) | $204.64 | −4.22% |
| Intel (INTC) | $65.76 | −28.58% |
| Broadcom (AVGO) | $326.08 | −5.48% |
| AMD | $504.80 | −10.88% |
| Micron (MU) | $884.74 | −5.30% |
The Philadelphia Semiconductor Index fell 7.20%, against 2.86% for the Nasdaq Composite and 1.82% for the S&P 500. The chip index lost more than 15% across October, so Friday deepened a slide that was already running.
Intel weak outlook: what the numbers say
| Metric | Q3 2026 reported | Q4 2026 guidance |
|---|---|---|
| Revenue | $16.5 billion | $15 to $16 billion |
| Adjusted gross margin | 44.1% | 38.0% |
| Adjusted EPS | $0.52 | $0.25 |
Computed from the midpoint: $15.5 billion is about 6.1% below Q3 and about 9.2% below the $17.07 billion analysts expected. Adjusted EPS would fall about 52%, and margin would drop 6.1 percentage points. Those are my calculations from the figures above.
Intel named three pressures. Higher memory prices and tight IT budgets are weakening PC demand. Substrate shortages and an accident at its Kiryat Gat factory in Israel limit what it can ship, with a roughly $300 million hit to Q4 revenue. And heavy factory spending means positive free cash flow is unlikely in 2027. Its data-centre and AI revenue still grew 78% to $7.3 billion, per INDmoney.
Why the chip stocks selloff spread beyond Intel
TradingKey reports that Amazon’s Q3 revenue and EPS missed expectations, and that it still plans about $220 billion in capital spending this year. INDmoney adds that AWS grew 39.3% to $46.0 billion, but trailing-twelve-month free cash flow was an outflow of $42.4 billion. Cloud demand is real; the worry is how long AI infrastructure spending can continue.
JPMorgan’s trading desk said renewed AI monetisation fears were deepening sector rotation. Raymond James’s Matt Orton argued the logic for AI spending beneficiaries is still solid. Both views come from TradingKey’s summary, not from the original notes.
Three different problems behind the chip stocks selloff
- Intel: its own forecast disappointed. PCs are weak and server supply is constrained.
- AMD: exposed to both PCs and AI chips. INDmoney notes its drop followed no bad news of its own and came before its 3 November report.
- Micron: record revenue of $54.23 billion in its last quarter, but investors worry about Chinese DRAM competitor CXMT and how long high memory prices last. Japan’s Kioxia fell 13.29% on 2 November after a weak outlook.
What tests the chip stocks selloff this week
Two AI hardware reports arrive tonight. See our AMD Q3 earnings preview and the Super Micro earnings preview. The question for AMD is whether its PC outlook looks like Intel’s. The question for Super Micro is whether huge AI server orders can produce cash. Super Micro itself fell 4% on 30 October and another 5% on 2 November, per 24/7 Wall St..
What the chip stocks selloff means for readers in India
AI chip prices flow into cloud bills, AI tool prices and laptop costs. Higher memory prices already make PCs dearer, which can reach Indian buyers. Many Indian investors hold US tech through funds, so check how much of one fund overlaps with others. This is news, not advice.
What we don’t know yet
- Whether the fall is a pause or a trend.
- Whether AMD’s PC business matches Intel’s weakness.
- How soon cloud customers slow AI spending, if at all.
- Exact intraday figures, which differ by source.

Frequently asked questions
Why did chip stocks fall on 30 October?
Intel’s weak outlook triggered it, and Amazon’s spending and results added fears about AI returns. The semiconductor index fell 7.2%.
Did Nvidia fall because of bad results?
No. Nvidia fell 4.22% because investors worried that high AI expectations leave little room for disappointment, not because its sales fell.
Is this the end of the AI boom?
The chip stocks selloff does not prove that. Amazon’s capital plan is still huge and Intel’s data-centre revenue grew 78%. The fear is about timing and cash.
Is this investment advice?
No. Askhari does not give personal financial advice.
Hari’s take
A chip stocks selloff makes every company look the same, which is the mistake. Intel has a supply and PC problem, Micron has a pricing worry, and AMD got caught in both. Tonight’s reports will show which stories are real.
I also notice that during this chip stocks selloff the same word, “AI”, covers both the strongest demand and the most expensive spending in tech. That tension will not be solved in a week.
