We haven't read much lately about big retail companies moving their headquarters, so we found reports about RadioShack leaving the Fort Worth area interesting. One area the company is supposedly considering for a new home is Tampa, FL.Also under consideration are Charlotte, NC; Nashville, TN; and Albuquerque, NM. Spokespeople for the retailer aren't talking about the possible move.The Shack, which has 1,700 employees, sold its 900,000-square-foot Fort Worth campus to a German firm after the retailer constructed the facility in 2005. A college then bought the complex last year and is giving RadioShack free rent through 2011.The potential move comes at an interesting time for the 4,470-unit chain. RadioShack's recent sales and earnings were down, but analysts upgraded the retailer's stock after it announced plans to sell iPhones.Additionally, it's rebranded itself as The Shack and has cut back its store based over the years. Would a new headquarters refresh the chain?
