Shares of GameStop Corp. rallied on Monday after Michael Burry, the money manager made famous by The Big Short, wrote that he has been buying the stock.

In a post on Substack, Burry expressed his confidence in the company’s chairman and chief executive officer, Ryan Cohen, who has tried a number of strategies to confront the challenges facing GameStop’s network of physical stores as online gaming becomes more popular.
