GameStop slides as revenue decline raises turnaround worries

GameStop shares fell 7% before the bell on Thursday on signs that it will take longer for the brick-and-mortar videogame retailer to stem a revenue decline due to tough competition and weak demand. Once a meme-stock darling, the company's third-quarter revenue fell and missed market expectations, underscoring the turnaround challenge faced by top investor Ryan Cohen, who became CEO and chairman in September. "Fundamentally the business needs a radical rethink," said Russ Mould, investment director at AJ Bell.
