Up more than 9% in pre-market trading, NOK scored a price-target hike to 2.50 euros from 2 euros at Wunderlich Securities after rival Samsung Electronics lost a high-profile court case against Apple Inc. (NASDAQ:AAPL). With a year-over-year loss of about 48%, it's not surprising that the equity has been the target of bearish speculation lately. Short interest on the security spiked by more than 29% during the last two reporting periods, and now accounts for a respectable 6% of the equity's float. It would take nearly four days to cover these shorted shares, at the stock's average pace of trading.
