Stock drops on scandal
Nvidia shares fell as much as 8% Monday, briefly putting about $350 billion of market value at risk, after reports tied CEO Jensen Huang to an alleged Chinese intelligence operation. The board has opened an independent investigation. The reports say Huang had a romantic relationship with a business executive whom U.S. intelligence believes was recruited by China’s Ministry of State Security. Huang told employees he was unfaithful to his wife, apologized and said he would cooperate. The board says it has no reason to believe company secrets or U.S. national security were compromised. It also expressed confidence in his leadership. No finding has shown Huang disclosed sensitive information or knowingly worked with foreign intelligence.
Pressure was already building
The controversy lands on a stock already under strain. Nvidia’s market cap fell from about $5.78 trillion on Oct. 6 to $4.51 trillion by Nov. 6, according to YCharts. That is roughly $1.27 trillion in lost value before the board publicly announced the probe. Investors have also questioned whether spending on AI infrastructure can keep growing at the same pace. Nvidia’s size adds market risk. It was 6.93% of the SPDR S&P 500 ETF on Nov. 6. At that weight, a 5.6% drop in Nvidia alone would cut about 0.39 percentage points from the S&P 500, assuming nothing else moved. In practice, other stocks would likely react too. Still, the S&P 500 rose 1.48% Monday morning and the Nasdaq gained 1.87%. Other chip stocks also climbed, suggesting investors saw the issue as company-specific for now.
Can Huang be replaced?
Huang co-founded Nvidia in 1993 and has led it since. Replacing him would be hard. The 63-year-old CEO built a centralized management style and holds key ties with customers, suppliers and governments. Analysts have asked whether Nvidia has an obvious successor. Chris Weston of Pepperstone told Reuters he did not expect Huang to resign. But he said a credible belief that Huang was leaving could trigger a severe selloff. Dan Ives of Yorkville Ives & Co. called Huang hard to replace, while noting the investigation could still lead to his removal. An affair alone does not automatically justify dismissal. The larger question is whether Huang’s conduct exposed sensitive information, created security gaps or hurt Nvidia’s business interests. So far, the company has announced no findings on those points.
Technical and political risks
Nvidia traded near $179.34 Monday, below its 50-week exponential moving average of about $199.16. The stock had already crossed below that line before the scandal, so the probe added to an existing bearish trend. A recovery above $190 and then above $199 would improve the technical picture. President Donald Trump has defended Huang, calling him honorable. But the case may complicate Nvidia’s push to sell advanced AI chips to China under Washington’s export limits. Congressional Republicans have asked for a private briefing on Nvidia’s security procedures, with a request for Huang to agree to a date by Nov. 11, according to Axios. Nvidia reports earnings Nov. 17. The board has not said when its investigation will end.
