On CAPS, 36% of the 306 All-Star members who have rated Green Mountain believe the stock will underperform the S&P 500 going forward. These bears include Motley Fool Hidden Gems co-advisor Seth Jayson (TMFBent) and TMFDeej, both of whom are ranked in the top 1% of our community.

A few months ago, Seth encouraged Fools to look past Green Mountain's soaring sales: "Wow, folks sure seem impressed by topline growth. My look at earnings of various types finds, well, not much. All the revenue growth in the world isn't going to help if [Green Mountain] ain't making much dough for shareholders."

Despite whopping sales growth, Green Mountain has habitually posted negative to low single-digit cash king margins over the past decade. In fact, Green Mountain's lack of cash generation, coupled with a soaring stock price, has it currently trading at a stiff price-to-operating cash flow of over 100. For perspective, rivals Starbucks, Sara Lee, and Peet's sport price-to-cash flow ratios ranging from the low to mid-teens. While a few Wall Street analysts have listed Green Mountain as the perfect takeover target for food giants hankering to get into the specialty coffee game, including Coca-Cola (NYSE: KO), Kraft (NYSE: KFT), and PepsiCo (NYSE: PEP), it's tough to imagine a substantially higher offer than today's already super-rich price.

CAPS All-Star TMFDeej sums up the bear case:

As I search for a few select shorts to hedge my mostly long CAPS portfolio, [Green Mountain] seems to fit the bill. I use a Keurig at the office and it's not bad, but I don't think that the company will experience the rapid profit growth that Mr. Market currently seems to be pricing in. One major headwind that Green Mountain faces is a huge increase in the price of coffee beans, which according to Barron's account for nearly a quarter of the Company's cost of goods sold. Coffee bean prices recently hit a twelve-year high. ...

In this sort of economic environment, it's easy to see consumers being hesitant to pony up a premium price for the convenience of Green Mountain's coffee products, when the good old coffee pot will do the trick at a fraction of the price.
