On CAPS, 37% of the 1,143 members who have rated Green Mountain believe the stock will underperform the S&P 500 going forward. These bears include useless33 and All-Star georcole.

Earlier this month, useless33 wrote that the Green Mountain bear case all boiled down to price: "Single serve coffee is convenient ... paring with [Starbucks (Nasdaq: SBUX)] is strategically relevant for both companies, but the price does not justify the earnings."

In fact, Green Mountain currently sports a rather lofty forward P/E of 36.2. That represents a premium to listed competitors Kraft (12.5) and Peet's (25.7), as well as its new giant partner, Starbucks (20.4).

CAPS All-Star georcole offers an inside view of the underperform argument:

I work in one of the largest grocery store chains in the Northeast. [Green Mountain] recently decided that they are not going to make the little bags of coffee so that we can brew our coffee by the pot anymore. [Green Mountain] made that decision, not us. So now we are going to switch over to another brand of coffee. How many other grocery stores, gas station convenience stores, restaurants, etc. are now going to have to go elsewhere for their coffee? Not a very good move [Green Mountain].

I know that they just signed a deal with Starbucks, but that is not going to be worth the increase that [Green Mountain] has experienced since the deal was announced.

If you put the two previous points together you are left with the impression that [Green Mountain] is concerned about picking up some sales (Starbucks), but not too concerned about losing a lot of regular customers that stop at the store on the way to work everyday for their cup of coffee. Why would they willingly give up that regular morning commuter crowd? I am baffled.
