Nvidia shares fall 7.2% after board opens investigation into spying allegations involving Jensen Huang

Nvidia's board announced on Sunday that it had opened an investigation into CEO and founder Jensen Huang's affair with a woman who has been identified as a spy acting on behalf of China.

Now comes the price tag.

Nvidia shares, the world's second-largest company by market capitalization, fell 7.2 percent in early trading in New York on Monday.

The decline runs counter to the broader market, with the tech-heavy Nasdaq Composite up 1.0 percent.

The broad S&P 500 and the Dow Jones Industrial Average are up 1.1 percent.
