Facebook has lost $119 billion off its market value.
It was the company’s worst trading day since going public in 2012 and among the biggest one-day losses of market value in U.S. stock market history.
The loss came a day after Facebook revealed that its user base and revenue grew more slowly than expected in the second quarter as it grappled with privacy issues.
Those revelations stunned investors, who believed the company had weathered the recent scandal over users’ privacy and pushed the stock to an all-time high Wednesday of $217.50.
In midday trading Thursday, the company’s market value, fell by more than $122 billion.
That means that in one day, just the decline in Facebook’s market value is roughly the entire market value of McDonald’s or Nike, give or take a few billion.
The company still has a total market value close to $511 billion, which exceeds the annual gross domestic product of countries like Poland, Belgium, and Iran.
Facebook was downgraded by a number of industry analysts who were caught off guard by slowing growth in the wake of the Cambridge Analytica scandal.
Company shares fell 19 percent Thursday.
