Green Mountain Coffee Roasters (GMCR.DL) was mysteriously up big this morning and, in the following video, Fool.com analyst Blake Bos gives his thoughts on the company.

Unfortunately, there is yet another lawsuit alleging that Green Mountain used a fulfillment vendor to falsify sales orders. There is also the continuing story line about competition from Starbucks' similar new single-serve device, the Verismo. Yet, in spite of this negativity, shares were still trading significantly higher. 

Blake suspects that the big pop in shares can be attributed to the company's huge short interest, which sits close to 40% of total shares outstanding. It's very easy for companies in this situation to go through some forced upside buying pressure as those short candidates seek to fulfill their orders at higher prices and push shares higher.
