mark zuckerberg facebook net worth Mark Zuckerberg's net worth tops $16 billion after Facebook earnings call

It’s a good week to be Mark Zuckerberg. Not that there really are many bad weeks for a 29-year-old billionaire. The Facebook CEO made a lot of money Thursday (July 25), following a strong earnings report for the second fiscal quarter of 2013.
Shares in the social networking website jumped to $34.68 at the close of trading Thursday, Forbes reports, the highest price for the stock in a year. With Zuckerberg owning 425 million of those shares, he’s sitting pretty, $3.7 billion richer. Not too shabby for a Thursday.
That makes Zuckerberg worth roughly $16.1 billion. It’s quite a change from September 2013, when Facebook hit an all-time low price of $17.73 a share. Still, Zuckerberg is a bit off from his highest net worth, which was $17.2 billion in March 2012. He seems to be bouncing back fairly well, though.
