Green Mountain Coffee Roasters, Inc. 7,434%
What have people spent a lot of money on over the past ten years? Coffee. Vermont-based Green Mountain roasts and sells gourmet beans, but what really accounts for the firm's fantastic rise is its 2006 purchase of Keurig, an outfit that makes single-cup coffee makers and the pods that go inside them. If you work in an office building, there's a decent chance you've got one of these machines down the hall.
