NOK was hit with some negative analyst attention this morning after the company's new Lumia smartphones failed to impress investors yesterday. Specifically, the stock was cut to "sell" from "hold" at S&P Capital IQ, while also receiving downgrades from Deutsche Bank and Societe Generale. With a 52-week decline of almost 63%, it stands to reason that skeptics have been gravitating toward the equity. Short interest on NOK has soared by approximately 32% during the past two reporting periods, and now represents more than 6% of the security's available float.
