Nvidia shares fell in premarket trading on Monday after its board opened a probe into chief executive Jensen Huang, even as the wider market went on to its best day since April. The chipmaker fell about 4.4 percent before the bell, according to morning market briefings, putting nearly 199 billion dollars of market value at risk, after dropping about 5.7 percent in after hours trading when news of the investigation first spread. For an index already in correction territory, it was one more test before the week biggest data release.
Why it matters
The probe centres on Huang relationship with a businesswoman reported to be linked to Chinese intelligence, and the allegations remain unverified. Huang admitted in a message to employees on November 8 that he had been unfaithful to his wife, and he has said he will cooperate fully with the investigation. Three House committee chairs have asked for a closed door briefing with Huang on November 18. The board investigation is independent, and it comes at a moment when the company is the most valuable chipmaker in the world and the centrepiece of the artificial intelligence trade that has driven markets for two years.
The market reaction was split. The S and P 500 jumped 2.35 percent on Monday to 7,549.94, and the Nasdaq Composite gained 2.74 percent to 25,253.14, while the Dow added 1,104 points to 52,389.75, in the best day for stocks since April. The VIX volatility index fell more than 22 percent to 19.92. Nvidia was the exception, closing more than 4 percent lower after falling nearly 9 percent during the session, and traders are balancing a broad rebound against a governance crisis at the company that symbolises the AI boom.
What happens next
The timing makes the probe harder to ignore. The October consumer price report arrives on Tuesday at 8:30 a.m. Eastern, and it is the last inflation reading before the Federal Reserve meets on December 8 and 9. Markets price roughly an 85 percent chance of a December rate increase after a jobs report that came in far stronger than expected, with 165,000 jobs added in October against forecasts of about 65,000.
What happens next will be decided by two things at once: the inflation number on Tuesday and what the Nvidia board finds. A hot inflation print would lock in the December hike and punish the same growth stocks that Nvidia leads, while a cool one would give the market room to recover. For now the message is that even the strongest company in the market can fall fast when questions reach the top.
