NEW YORK — Facebook shares fell 5 percent Tuesday on reports that CEO Mark Zuckerberg agreed to testify in front of Congress about the company’s data scandal.
The crisis began on March 16 after Facebook said it was suspending data analysis company Cambridge Analytica for allegedly harvesting data from more than 50 million Facebook users. Cambridge Analytica worked on Donald Trump’s presidential campaign.
Since then, Facebook’s stock has plunged 18 percent, wiping out nearly $80 billion from the social networking giant’s market value in the process.
Zuckerberg’s net worth has fallen by about $14 billion (he is still worth $61 billion, though).
Tech stocks in general have taken a hit since the Facebook allegations first came to light. The Nasdaq is down 6 percent.
And other social media companies, most notably YouTube owner Google and Twitter, have both nosedived as well.
Shares of Google parent Alphabet fell 7 percent since March 16, while Twitter has plunged 20 percent.
Twitter was down 12 percent on Tuesday after noted short seller Citron Research has changed its tune on the company’s stock.
Investors worry that Facebook, Google and Twitter could face tougher regulations in the United States and around the world because of the Cambridge Analytica controversy.
If that happens, it could stymie growth for all three companies — but Facebook in particular.
Investors also worry that users might flee these companies because of privacy concerns. And if users flee, advertisers may eventually jump ship too.
That’s why several Wall Street analysts have lowered their price targets and earnings estimates for Facebook during the past week and a half.
But others have boosted their forecasts, arguing that the worst will soon pass and that investors are overreacting.
It’s impossible to know if it’s the Facebook bulls or bears who will ultimately be proven correct. But it’s clear that confidence in Facebook and other once-hot tech companies has been shaken.
“While the scandal is likely to blow over, investors should be aware that a continued sell-off in this sector would not be surprising, and if another scandal were to hit, it just might break the tech sector’s back,” said Craig Birk, executive vice president of portfolio management at investing firm Personal Capital in a note Tuesday.AlertMe
