$GameStop(GME)$When we see moves like these where we are at 400 one day and under 100 another .. it is sad but someone else was stuck with the bill while someone stood to gain. At one point it was hedge funds. Which is fair as they are forced to cover. 

But when the short interest dipped, and there was the buying frenzy, the person stuck with the bill was the retail investor that was blinded by possible opportunity and entered at $300 only to find his portfolio down 70% now.
