Executives of some beaten-down companies, including one battered biotech name and a popular soft drinks maker, scooped up shares of their own stock in the past week. Here are the top insider buys: Energy Transfer — Executive Chairman Kelcy Warren bought one million shares Monday at $13.53 per share for a total value of $13.53 million. Shares are up more than 2% over the past month. Enstar Group CEO bought swathes of shares Wednesday, the day after the company reported its earnings for the third quarter. The stock has gained about 8% so far this year and shares are up roughly 4% over the past month.
