Money | Mark Zuckerberg Sinking Stock Pushes Zuck Off Billionaires Index As of yesterday, he was no longer one of world's 40 richest By Kate Seamons Posted May 30, 2012 8:33 AM CDT Copied In this Oct. 6, 2010 file photo, Facebook CEO Mark Zuckerberg checks his cell phone after a product announcement at Facebook headquarters in Palo Alto, Calif. (AP Photo/Paul Sakuma, File) As of yesterday, Priscilla Chan was no longer married to one of the world's 40 richest people. Bloomberg reports that Facebook's much ballyhooed drop below the $30-a-share mark yesterday caused Mark Zuckerberg to drop from the list. With the stock closing at $28.84, his fortune decreased from $16.2 billion on Friday to $14.7 billion yesterday. That boots him off of Bloomberg's daily Billionaires Index, and behind Luis Carlos Sarmiento, the richest man in Colombia. To hop over him, Zuck's wealth will need to rise $800 million. He's off to a less-than-promising start: Shares opened at $28.40 this morning, down 44 cents. Read These Next Trump reportedly wants a $230M payout from the DOJ.
