Dish Network Corp shares could jump 20 percent over the next year if the Federal Communications Commission’s wireless spectrum auction prompts investors to revalue the company’s wireless real estate, Barron’s said in a story published Sunday. The third-largest pay-TV provider in the U.S., Dish Network owns undeveloped wireless spectrum that bullish analysts think could be worth $25 billion, Barron’s wrote. “Just from a stock perspective, you don’t have to have a view on what Dish is ultimately going to do with the spectrum,” Jason Bazinet, an analyst at Citigroup, told the financial newspaper.
