Nvidia shareholders filed a class-action lawsuit against the company and CEO Jensen Huang after shares fell 4.27% to $178.67. Prosecutors accuse management of concealing ties to the former chief executive of Singapore's Mega Speed International Alice Huang, who American intelligence agencies suspect worked for Chinese intelligence, writes Reuters. According to the investors, hiding the risks to US national security misled them and led to the loss of approximately $190 billion of the company's market value in one day.
