Coffee peddler Green Mountain Coffee Roasters ( NAS: GMCR ) and energy-drink pusher Monster Beverage ( NAS: MNST ) (formerly known as Hansen Natural ) also had caffeinated returns of over 7,000% over the decade, and both could also count every single person as a possible stomach for their products. Green Mountain benefited from its purchase of Keurig in 2006, which now boasts 80% market share of single-serve coffee. Monster saw its energy drink take off, fighting with industry leader Red Bull for market share. Both companies multiplied their revenues in the face of a bad economic decade.
