Edwards Lifesciences (NYSE:EW) investors have had enough headaches over the recent past. The company's stock has spiraled down, exacerbated by the firm's recent downbeat earnings report that showed sales of its Sapien heart device missing Wall Street's expectations. To bring back investor confidence, the company recently announced a $750 million buyback to help stabilize the stock.
