Facebook co-founders dumps 450,000 shares

The 28-year-old billionaire, Facebook's co-founders, Dustin Moskovitz has joined the ranks of major players in the company who have recently unloaded major portions of their stock, the NY Times reported.

Moskovitz unloaded 450,000 shares, or about 6% of his holdings in the company he helped start at Harvard, according to documents filed with the Securities and Exchange Commission.

Moskovitz, who is on Forbes' list of billionaires, began selling the Facebook shares late last week and continued through Monday, according to the documents made public Tuesday. He made three sales of 150,000 shares each, for a total of about $8.8 million. Moskovitz still owns 7.05 million shares, worth more than $137 million, based on Facebook's closing stock price Wednesday.

But Moskovitz's share dump didn't compare to that of Peter Thiel, who was one of the earliest people to invest in the social network.

In an SEC filing Monday, Thiel was revealed to have cashed out more than 20 million shares for about $396 million.

Thiel's recent sale, along with his shares sold during Facebook's IPO in May, have turned his early $500,000 investment in Facebook into a more than $1-billion return.

Facebook shares closed at $19.44 on Wednesday, up 1.46%.
