Electronic accessories maker ZAGG (NASDAQ:ZAGG) is down about 50% from its 2011 peak. Among the many headwinds it's been facing is the perception that it's tough competing in a commodity market. Not only are margins hard to grow, but competition is tough both within ZAGG's space, and outside of it. Corning (NYSE:GLW), for example, has introduced newer and tougher Gorilla Glass each year, causing less demand for screen protectors. And whenever Apple (NASDAQ:AAPL) includes covers for its products -- as it did with iPad 2 -- ZAGG inevitably loses sales.
