Caribou Coffee ( CBOU) is plagued by guilt by association with Green Mountain Coffee Roasters ( GMCR), which reported a poor quarter and guided significantly lower for the near future. Green Mountain suffers from inventory problems -- specifically, from having too many Keurig machines and K-Cups on hand and in channels. It is also still under the cloud of an SEC investigation into its accounting practices. Finally, the company ousted its founder and CEO. So when Caribou Coffee reported results that were 2 cents better than expected, the company warned that because of moderating K-Cup demand, the company was lowering its growth expectations to a range of 6% to 8%, from 10%. When you read between the lines, we see that Caribou is suffering because of Green Mountain's problems, not because of any mistake that Caribou made itself. Caribou stock now sells at 37% below its all-time high set in April and is an excellent long-term investment. Falling coffee prices will be offsetting any perceived sales slowdown in the future.
