Mark Zuckerberg just got promoted: he's now the fourth-richest person in the world.
Zuckerberg, propelled by Facebook (NASDAQ: FB)'s incredible stock performance, shoved Amazon (NASDAQ: AMZN) CEO Jeff Bezos aside on Tuesday to claim the fourth highest ranking on the Bloomberg Billionaires Index.
Facebook founder Zuckerberg, 31 and arguably the most effective CEO in America, was sitting on a fortune worth $50 billion U.S. by the close of trading Tuesday, according to Bloomberg.
