Nvidia lost $1.6 trillion after Jensen Huang's exit, but Apple's and Uber's CEO transitions offer a blueprint

Jensen Huang's abrupt departure from Nvidia (NASDAQ: NVDA) after 33 years at the helm has sent the chipmaker's shares tumbling. But the bigger question for investors is whether Nvidia can maintain its dominance in artificial intelligence without the man who helped build it. Huang resigned on Nov. 12 amid an investigation into his relationship with Alice Huang, a businesswoman who U.S. intelligence agencies suspect of passing information to China. Nvidia has said it has no reason to believe company secrets or national security were compromised, although its investigation remains ongoing.
