NEW YORK (AP) — GameStop shares jumped around 12% in premarket trading this morning after the video game retailer appointed a committee it said would aim to “transform GameStop into a technology business.” Named to the committee were Alan Attal, Kurt Wolf and Ryan Cohen, co-founder of the Chewy online pet-supplies company. Cohen, who will serve as chair of the Strategic Planning and Capital Allocation Committee, is also a big shareholder of GameStop and on its board of directors. GameStop backers see his involvement as a reason to bet on a successful transformation for the company into a successful digital powerhouse.
