GameStop, the video game retailer at the center of a social-media driven investment frenzy, says it lost $215 million in the 12 months ended Jan. 30 as it dealt with pandemic-related shutdowns and moved to transform itself into a more online-focused company. The company’s latest results offered few positives to back up some investors’ belief that the struggling retailer is on track to turn its business around and perhaps justify its stock’s stunning run from around $20 a share at the start of the year to north of $480 by the end of January. The stock closed at $181.75 in Tuesday trading.
