Sprint Corp shares were seen up 5.1 percent on Tuesday on reports the company has entered exclusive discussions with Comcast Corporation and Charter Communications, Inc. about a potential wireless service deal. Details of the discussions are fuzzy at the moment, but the news of ongoing talks was enough to get Wells Fargo analyst Jennifer Fritzsche’s attention. “We believe Sprint is one of the most interesting stocks on our wireless list right now,” Fritzsche wrote in a new note. The latest news just adds to the list of potential catalysts for Sprint, including M&A potential, margin expansion and deployment of 2.5 GHz spectrum, Fritzsche wrote.Source
