In the following video, Fool industrials analyst Blake Bos discusses unmanned aircraft systems maker AeroVironment (NASDAQ:AVAV) and tells investors what's behind the recent spate of insider stock buys at the company. Fears of major defense spending cuts on the horizon have put a lot of selling pressure on the stock in recent months. Could these buys be a good sign? Blake gives us his take on whether this signals a buy.

Editor's Note: In the video below Motley Fool Analyst Blake Bos states no insiders have made open market purchases. This statement was incorrect, Director Arnold L. Fishman purchased 50,000 shares in the month of April on the open market. This could be viewed as a positive sign for the company, as a key insider is accumulating shares on the open market. The Motley Fool regrets and apologizes for this error.
