Shares of Nokia have jumped in New York trading after Bloomberg's Ed Hammond, Dinesh Nair, Myriam Balezou and Niclas Rolander reported, citing sources, that the company is working with advisers to consider potential asset sales and mergers. The network equipment maker has been under pressure due to fierce competition and its shares have lost roughly a third of their value over the past year, prompting the review of potential alternatives, according to the report. Following Bloomberg's report, Nokia shares spiked. Although they have come off their highs, the shares are up 28c, or 7%, at $4.19 at the time of this writing.
