CEO Constantine Karayannopoulos bought $100,002 worth of Molycorp Inc. (MCP), buying 16,667 shares at a cost of $6.00 a piece. Before this latest buy, Karayannopoulos made one other purchase in the past year, buying $100,000 shares for a cost of $10.00 a piece I guess he figured he'd off set his losses from earlier $10 lol
