By Krystal Hu and Sinéad Carew NEW YORK (Reuters) - Joe Youngblood, who works in digital marketing in Dallas, Texas, bought his first share of GameStop at $98 in early February and found his investment cut in half in a matter of days. After a wild ride, he is now up more than 200% and expects the video game retailer to initiate a much-awaited turnaround of its business. "I am kicking myself for not buying more when it dropped below $50," said Youngblood. "After research I believe GameStop has a good chance to pull it off." The latest resurgence in GameStop shares has reinvigorated true believers. Still, many analysts point to the rally in beaten-down "meme stocks" championed in forums such as Reddit's WallStreetBets as evidence for speculative excess in stimulus-fueled markets.
