Green Mountain Coffee (GMCR -3.8%) and Starbucks (SBUX -1.9%) head lower after Nielsen estimates Starbucks' K-Cups only claimed 12%-14% market share in the 4 weeks ending March 17. However, Goldman isn't too worried, predicting Starbucks K-Cup sales will rise after the products begin to be offered in company stores this fall. International expansion is expected to drive growth in later years.
