After surging to an all-time high of $86.97 several months after its 2014 IPO, shares of action-camera maker GoPro (NASDAQ: GPRO) rapidly declined as revenue growth slowed. For most of the last year, the stock has traded well below its IPO price of $24 per share. The company posted losses in the past three quarters, which seems to confirm concerns that the action-camera market, and GoPro specifically, has limited growth potential.
