The effect of fake news in the 2016 US election and user privacy concerns caused social media giant’s shares to plunge by about 20 percent.
Facebook‘s stock has taken a nosedive, wiping out about $120bn in market value.
The plunge comes after earnings fell short of expectations following a series of scandals.
The company’s profit still surpassed those of the previous year, but it was the first time since 2015 that Facebook’s profits failed to meet performance estimates.
