Nvidia shares lost a few hundred billion dollars in value this week after CEO Jensen Huang admitted an affair with Alice Huang, whom US authorities regard as a suspected Chinese spy. Law firms including Rosen Law Firm and Schall, Brown & Schwartz are urging investors to join claims that Nvidia made false or misleading statements and failed to disclose key information. President Trump said the FBI is looking into the matter and called Huang an honourable guy who probably has an excuse for the affair with an alleged spy. The articles add that Nvidia had earlier denied any relationship beyond a normal business one, and had vouched for Megaspeed, a Singaporean data centre company Alice Huang is reportedly connected to. Huang has since said the relationship was not a normal business relationship, and Nvidia's board is investigating whether he was the target of foreign intelligence, saying it has no reason to believe national security or Nvidia secrets were compromised. Huang is due at a closed-door meeting with Congress committee leaders on November 18. PC Gamer reported that Trump said he had been told last year that a Chinese spy was targeting Huang, and that Trump did not regret not acting on it.
