WASHINGTON (AP) — Key players in the GameStop saga are testifying to a House committee Thursday. Lawmakers are examining whether the wild swings in the stock price of the video game retailer exposed conflicts in the market’s structure that can hurt unsophisticated investors. The episode has been portrayed as a victory of the little guy over Wall Street titans, but not everyone is buying it. Lawmakers from both parties are among the skeptics. GameStop shares soared 1,600% in January before falling back to Earth. Entangled in the drama are huge short-selling hedge funds, a social media message board and ordinary investors wanting in on the hottest new trade.
