OPK Health doesn't have any fundamental reasons for making such jumps as they made it today. The only reason for that (as I think) is the following:Phillip Md Frost, a major owner of Opko Health Inc and Opko Health Inc's CEO & Chairman and a director of the company, recently acquired 11,900 shares of the company. This is not the only post about this guy and OPK Health. It seems that he is trading more than running the business. I'd better think about it before buying this stock. And I assume this stock will bounce back in close future. Moreover, it can't last forever. Traders should just avoid such moves from him just because it doesn't mean that the business is so good that it's owner is picking up his shares.
