Mark Zuckerberg had a terrible, horrible, no good, very bad day yesterday.
According to a report by CNNMoney, the Facebook founder suffered a $3 billion loss in the value of his Facebook stock on Thursday, one of the largest single-day losses ever for an individual investor.
The report had it that Facebook shares plunged 5.5% after the chief financial officer warned investors that the company expects revenue growth from advertising to “come down meaningfully”.
Zuckerberg holds 418 million shares of Facebook stock, still good for about $50.2 billion.
Bloomberg estimates Zuckerberg’s total net worth at $52.2 billion, ranking him as the fifth-richest man in the world, just behind Warren Buffett.
And despite Thursday’s plunge, Facebook shares are up nearly 15% for the year, lifting Zuckerberg’s net worth by $6.4 billion.
