NEW YORK ( TheStreet) -- I'm long BlackBerry ( BBRY). Therefore, you can imagine I was thrilled to see Societe Generale upgrade the company to buy from sell yesterday. The stock jumped 6%, and it's up another 2% today. Given that I'm long the stock, I'm biased to think it is "cheap" and deserves all the upgrades it can get. However, I've got to be straight with you: the Societe Generale report simply makes no sense. Let me summarize. BlackBerry will next report earnings on June 28 for the May quarter. This is a battleground stock to say the least. Short interest on the float is in the mid-to-high 30% range. The revenue and earnings estimates for the May quarter are all over the map on Wall Street. Bears believe the June 28 report will be the beginning of the end for the company. Bulls think it will be the start of an amazing comeback.
