"It's interesting to watch stocks grow and watch them fall," said Jaydyn Carr, a fifth grader who made a 5,000% profit on stock in the video game retailer GameStop. His mother bought him the stock as a Kwanzaa present before it rose in price so dramatically. "One of the biggest things you're going see here is how everybody got swept up in this," Jarvis said. They were swept up in the big increase that Wall Street hedge funds were betting would fall. In the parlance of the financial world, they were short selling GameStop.
