In this video, Motley Fool industrials analyst Blake Bos takes a look at unmanned aircraft manufacturer AeroVironment (NASDAQ:AVAV) and its lackluster performance over the past few years. He discusses how the company has suffered recently in a difficult defense spending environment, but notes that the company recently received FAA approval for restricted commercial use. He believes that the optimism over the opportunity in the commercial/civilian sector is the reason the stock is trading at such a premium today, despite the pressures to its top line at the moment. Blake also examines the key things to watch from here and how to know if this opportunity will pan out.
