On August 20, 2012, an SEC Form 4 form was released for Facebook founding investor and board member Peter Thiel, showing 20 million shares sold for a profit of nearly $400 million. Since May 22, 2012, total company stock sales for the Facebook director have eclipsed $1 billion.

Raising eyebrows, the venture capitalist dumped 80 percent of his remaining shares, essentially cashing out shortly after the required trading lock-down for investors was lifted. At GMI Ratings, we’ve rated the company a solid “D” since its IPO.
