Nvidia shares fell 4.27% to $178.67 on Monday, the first trading day after its board opened an independent investigation into reports that CEO Jensen Huang was the target of a foreign intelligence effort. On the same day, AMD rose 13.3% and the Nasdaq gained 2.74%.
That gap is the whole story. Investors didn't sell chips. They sold Nvidia.
What Trump said, and why it cuts both ways
Speaking at the White House, President Trump said he had called Huang "just to see if he's feeling all right," and that Huang "said he had absolutely no idea that the person in question was a spy." Trump added: "I know the FBI is looking into it in terms of something else, and I think that he'll be in good shape."
For investors, that's support and a warning in one sentence. The President is backing the CEO. But he also confirmed that the FBI is involved, which makes the matter bigger than an internal board review.
There's a political layer too. The reports involve China, and chip sales to China are already one of the most closely watched issues in Washington. Public backing from the White House lowers the risk of a sudden policy reaction, at least for now.
Why the selling may be overdone
The board has said it has no reason to believe company secrets or national security were compromised. Joachim Klement of Panmure Liberum said the impact so far looks contained to Nvidia, and Monday's trading backs that up: AI demand isn't what's being questioned.
The fall itself is also in line with history. In past cases where a CEO left after a board review, the stock dropped about 5% on the first day, according to 24/7 Wall St. Nvidia fell a little less, and its board has expressed confidence in Huang.
The risk: this time the doubt is about China
The FBI changes the timeline. A government inquiry can run longer than a board review, and Nvidia doesn't control it.
China sales are already sensitive. The reports involve a former executive of a Singapore company that reportedly bought more than $4.8 billion of Nvidia chips. Any link to export rules would be a business issue, not just a personal one.
Earnings are a week away. On 17 November, management will face questions about the probe and the AI outlook in the same call.
What would settle it
A quick update from the board's committee, or a clear statement that no export rules were broken, would likely close much of the gap with other chip stocks. Silence until earnings would keep a discount on the shares.
The AI trade is recovering. Nvidia now has to prove the problem is a headline, not a business risk.
