• Nvidia shares dropped sharply in after-hours trading on Wednesday after reports that CEO Jensen Huang had an extramarital relationship with a company executive and that the board is meeting to discuss his future.

• Days earlier, Nvidia’s board said it would investigate whether Huang was the target of a foreign intelligence effort amid reports that he had a separate relationship with a woman US officials believe to be a Chinese spy. Huang on Sunday apologized for an extramarital affair, although he did not name the other party.
