Nvidia falls 4.27% as Nasdaq gains 2.74%; board opens probe into Jensen Huang

The notable signal is the divergence: Nvidia fell against a sharply higher Nasdaq and a strong semiconductor index, suggesting the board probe is being priced as company-specific risk rather than sector weakness. The board's framing — an independent review of whether Huang was a target of foreign intelligence activity, with no evidence of compromised secrets — puts governance and key-person exposure at the center for a stock whose valuation leans heavily on its CEO. Whether the investigation stays narrow and how the board communicates its findings are the open questions worth watching.
