Some rookie investors are sad that they cannot continue to ‘wind up’ or ‘get at’ Hedge Fund Managers by making a run on the stocks of several publicly traded companies including GameStop, Express, Bed Bath and Beyond that the NASDAQ system had a short ‘M’ Automatic flag on trading that stopped action on these stocks temporarily on Wednesday morning January 27 2021.
