Shares of Facebook Inc fell more than 5 per cent on Monday after the U.S. consumer protection regulator made public its investigation of how the social network allowed data of 50 million users to get into the hands of political consultancy Cambridge Analytica.
Scrutiny by the U.S. Federal Trade Commission, which generally confirms the existence of an investigation only in cases of significant public interest, adds to pressure by lawmakers in the United States and Europe for Facebook Chief Executive Mark Zuckerberg to explain how his company handles user data.
Facebook shares briefly dipped below US$150 on Monday for the first time since July 2017, before recouping some losses. They were down 3.1 per cent at US$154.37 in afternoon trading.
At the day’s session low the company had lost $100 billion in market value since March 17, when newspapers first reported that Facebook member data was improperly used by consultants Cambridge Analytica to target U.S. and British voters in close-run elections.
