Shares of Nvidia fell Monday morning after the company opened an investigation into chief executive Jensen Huang, according to The Hill.

The Hill reported that the stock opened down 7.3 percent from Friday's closing price and fell to $170.24 per share during early-morning trading. Its summary said this level marked the lowest point, but the available text was cut off before giving further detail.

According to The Hill, the investigation concerns Huang's reported affair with a woman whom U.S. intelligence officials believe is a Chinese spy. The Hill described these matters as reports rather than confirmed findings.

ABC News reported that Nvidia stock fell Monday morning in the first trading session since the chip giant said it had opened an investigation into Huang. Its summary did not include a percentage decline or a share price.

The two reports differ in detail. The Hill gave specific figures for the opening and early-trading prices, while ABC News gave none. The summaries reviewed for this story do not include a statement from Nvidia or Huang beyond the announcement of the investigation, and they do not describe its scope, timing, or outcome.
