The New York Stock Exchange repeatedly halted trading in the stock of the video game retailer GameStop on Feb. 25 as its price surged above $100 per share in overnight trading. The stock has been favored by small investors who congregate on the Reddit forum r/Wallstreetbets.
By 10 a.m. on Feb. 25, the exchange had blocked trading of GameStop four times, at 9:33, 9:42, 9:48, and 9:56 a.m., each time for about five minutes. That means traders were only able to buy it for about 10 minutes in the first 30 minutes after the exchange opened.
