Intel plunged 28.6% for its worst drop since 1974 — and the AI sell-off gave the S&P 500 its worst day since June
A drop of 4.2% for Nvidia, the chip company that became the poster child of the AI frenzy, was the heaviest force pulling the S&P 500 downward.
What it means
- What to watch: This one turns on a concrete figure (28.6%); set it against the recent trend before reading it as a turning point.
- How the stocks are trading: $INTC -29.50%, $^GSPC -1.82%, $NVDA -4.04% in the latest session.
- Timing: It landed after the close, so the session change beside it was final before the story existed. The next session is the first that could react.
Where the stock stands
$INTC last traded at $64.91, -29.50% on the session. That is 54% below its 52-week high of $142.35 and 97% above its low of $32.89 — in the lower part of the range. Over the year it has ranged 333% from low to high: a very wide band for one year, the kind of volatility where large swings are routine. $^GSPC last traded at $7,580.07, -1.82% on the session. That is 3.4% below its 52-week high of $7,844.52 and 20% above its low of $6,316.91 — in the upper part of the range. Over the year it has ranged 24% from low to high: a moderate band. These are latest-session quotes, not live prices.
How much coverage it is getting
Wook has stored at least 300 stories about these names in the last 30 days, 80 of them this week. At its 30-day pace you would expect about 70 a week, so this week is about normal. Across those stories the wording ran 21% bullish, 64% neutral and 15% bearish. This one reads bearish, so it sits in a small minority of the run. 20 came from Fortune and the rest from other outlets, so the coverage is broad rather than one desk returning to the story. 12 related stories — same name or same desk — are lined up beside this one if you want the whole thread.
The bigger picture
In tech and AI, follow the capex. What the largest companies spend on chips and data centers — and whether that spending shows up as revenue — moves these names more reliably than any keynote. On Wook's supply-chain scanner, Information Technology reads elevated today.

What to watch next
The $INTC page has the full chart, the filings and the valuation model behind these figures. Comparing how two or three outlets frame the same story is the quickest way to separate the facts from the angle. Wook AI, above, can pull live figures and do the math — how far $INTC is from its high, or how this week's coverage compares — on request.
How this analysis was made
Fortune published it, and Wook filed it under Tech & AI. It reads bearish at high severity because of “drop”, “plunge” and “sell-off” in the wording, with nothing on the bullish side to offset them. It was matched to $INTC, $^GSPC and $NVDA; a company mentioned in passing is tagged the same as the subject, so check which one the story is really about. It carried 28.6% and 4.2%, shown as published and not recalculated. The preview above is the publisher's own wording.
The tone and severity labels come from a fixed word list — no editor, no AI, no crystal ball — so they describe how a story is worded, not what happens next. They are not a forecast or a recommendation, and a same-day move does not mean this story caused it. Not investment advice.
