An insider sold GoPro shares recently, but they didn't buy any. And there weren't any purchases to give us comfort, over the last year. While insiders do own shares, they don't own a heap, and they have been selling. So we'd only buy after careful consideration. So while it's helpful to know what insiders are doing in terms of buying or selling, it's also helpful to know the risks that a particular company is facing. While conducting our analysis, we found that GoPro has 2 warning signs and it would be unwise to ignore these.
