Why I'll Never Own Under Armour Stock

Warren Buffett once said: "If you aren't willing to own a stock for ten years, don't even think about owning it for ten minutes." In order for there to even be a remote possibility of owning a stock for that long, the company must have a competitive advantage, and I don't believe Under Armour has one. Nike's strength in footwear, where it gets most of its revenue, provides it with a competitive advantage, as footwear has higher barriers to entry and requires technical and innovative expertise.
