October 30, 2026 | TickerRoast Markets Analysis
Semiconductors were the best place to be for most of the AI boom, and on Friday they were the worst. The PHLX Semiconductor Index was down about 9% by mid-afternoon. Intel’s outlook started it, but the scale of the losses at companies with very different businesses tells me this was a sector-wide reset of expectations, not a verdict on one company.
Intel’s Forecast Set Off the Slide
According to Intel’s earnings release, third-quarter revenue rose 21% to $16.5 billion and non-GAAP earnings were $0.52 a share, and CFO David Zinsner said data center revenue grew at its fastest pace in 15 years. The problem was the guide: Intel forecast fourth-quarter revenue of $15.0 billion to $16.0 billion and non-GAAP earnings of $0.25 a share, and said it expects the PC slowdown to continue at least through the first half of next year. Yahoo Finance puts the average analyst estimate for fourth-quarter revenue at $17 billion.
Intel shares were down about 31% at around $63.50 shortly after 3 p.m. Eastern, based on Yahoo Finance data, a move Bloomberg describes as the stock’s largest drop in more than four decades. A company guiding revenue down from the quarter it just reported, while saying demand for its server chips exceeds what it can supply, raises a question investors had been willing to ignore: how much of the AI demand reaches chipmakers as profit, and how much is lost to supply constraints and cost.
The Rest of the Sector Followed
The losses were steep across the group. AMD was down about 12.8%, Micron about 7.4%, Broadcom and Taiwan Semiconductor’s U.S.-listed shares about 7% each, and Nvidia about 5.4%, according to Yahoo Finance quotes. The VanEck Semiconductor ETF was down about 8.4%. The Associated Press reported that Nvidia’s fall was the heaviest single weight on the S&P 500, because of its size.
The timing matters. This week the largest buyers of AI chips reported record capital spending: Amazon $77.3 billion in the quarter, Alphabet $51.4 billion, Microsoft $39.4 billion and Meta $34.9 billion, according to their filings. That spending is chipmakers’ revenue. When investors start to question whether the buyers can keep spending at that pace, the suppliers with the richest valuations are the first to be repriced, even when nothing in their own order books has changed yet.
What I Am Watching Next
Nvidia’s next quarterly report is the result that matters most for the whole group. Until then, the useful signal is whether the hyperscalers’ capital spending plans for 2027 stay intact. If they do, Friday’s drop will look like a valuation reset; if they are trimmed, chip revenue estimates for next year will have to come down.
