Nvidia shares slump amid investigation into CEO Jensen Huang

The California-based semiconductor giant's stock dropped significantly as markets opened, while broader tech indexes rose. The probe follows reports that Huang developed a close personal relationship with a Chinese business executive from a partner company who allegedly passed information to Beijing.

In a letter to employees, Huang admitted to infidelity but did not elaborate on the relationship details. "NVIDIA's Board of Directors has initiated an independent investigation. I support the investigation and will cooperate fully," he stated.
