Nvidia and CEO Jensen Huang are hit with a shareholder lawsuit over his reported relationship with a woman suspected of spying for China. The lawsuit, filed Monday in federal court in San Jose, California, accuses Nvidia and Huang of misleading investors by failing to disclose potential national security concerns tied to the alleged relationship. Huang told employees he had been unfaithful to his wife but did not address his reported relationship with Alice Huang, a former executive at Singapore-based chip buyer Megaspeed. Nvidia shares closed down 4.3%, wiping out approximately $190 billion in market value. Shareholders filed the lawsuit just five minutes after the closing bell. See the allegations in the full story:
