By Christina Cheddar Berk, News Editor NEW YORK ( CNBC) --It's going to take more than a new CEO to fix Best Buy'sproblems, but at least it's a start. At best, it's a signal the board is getting ready to be more aggressive about shaking things up and reinventing the brand. Although Best Buy ( BBY) shares popped after the news broke that Brian Dunn resigned and a search for a new CEO is underway, the euphoria was short-lived and Best Buy shares have since retreated. That is likely an acknowledgement of the tough task ahead. "They need a new, strong operating CEO to help come in and do some radical things to make some changes," said Joe Feldman, assistant director of research at Telsey Advisory Group.
