I do really like when somebody from the management or shareholders pick up some shares of the company. It indicates that the affiliated parties believe in the company's upside potential. Most likely they know the situation better than other traders. Here is the same situation with Opko Health: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 15,000 shares of the company. The buys took place at prices ranging from $7.74 to $7.97 per share, on February 16, 2016. The only thing that worries me here is that Opko Health is a pharmaceutical company, this sector is super-volatile and everything depends not on your project or products but on your competitors. What do you think about Opko Health?
