Nvidia drops 4.4% to $178.51 on the Huang probe, wiping about $196 billion off its market value

Update to our Sunday report: Nvidia stock traded at $178.51 at 10:41 AM ET on Monday, down $8.13 or 4.36% from Friday's $186.64 close, according to Nasdaq.com data. The board's independent inquiry into CEO Jensen Huang's relationship with a Megaspeed executive is the reason markets gave, per Fox Business and the New York Post.

The numbers behind the drop

• Market value: $4.30 trillion at the time of the quote, which implies about 24.1 billion shares. Friday's close to Monday's price is $8.13 a share, or roughly $196 billion (our calculation from Nasdaq's quoted values).
• Day range: $170.24 to $179.92, so the stock touched about 8.8% below Friday's close before recovering part of the loss.
• Volume: about 190 million shares by mid-morning, against an average of about 115 million.
• 52-week range: $164.27 to $243.37. Monday's low is about 3.6% above the 52-week low. Our chart shows the stock about 25% below its October 6 peak.

What the board and Huang have said

The board said it has "no reason to believe that either national security or NVIDIA secrets were compromised," while the inquiry "will examine all available information," according to Fox Business, citing Sunday's statement. Huang separately apologized for being unfaithful to his wife and said "there is no excuse for what I did." He did not elaborate on the relationship, Fox reports.

The New York Post reports that the inquiry will also look at whether Huang misled the board or shareholders about the relationship. That is the Post's description; the board's published statement quoted above does not say so. President Trump called Huang an "honorable guy" on Sunday night, the Post reports.

China's foreign ministry rejected the underlying allegations when the New York Times first reported them. On October 30 spokesman Guo Jiakun called the reports groundless and an attempt to smear China, according to SCMP. We did not confirm a new Beijing statement on Monday. The allegations remain reported U.S. intelligence assessments, and no charge has been made public.

Why the date matters

Nvidia reports third-quarter results on November 17, per Nasdaq.com, and House Republican chairs have asked Huang for a closed-door briefing on November 18 (our earlier story). The Post notes Huang has about 60 direct reports and that his daughter, son and son-in-law work at the company, which is why analysts describe any outcome that separates him from the company as hard to execute.

Who it hits

Index-fund holders carry Nvidia as one of their biggest positions, so a stock-specific governance story shows up in 401(k) balances. Options traders face wider swings into the 17th. Small AI-hardware resellers and data-center builders that depend on Nvidia supply are watching whether the inquiry touches Asian distribution partners.
