This was me. I lost money on GME betting on the fact that more shorted shares still had to be covered.
The short squeeze wasn't a complete failure. It happened, it was just much smaller than many predicted. I still wonder what would've happened if Robinhood didn't shut off demand by preventing people from buying shares. My investment thesis didn't foresee this happening. I don't think anyone did.
The other large part of the problem was that a lot of people, including myself, were going off of stale short interest data. Updated estimates for GME were reported to be 39% of float vs +100% on 1 Feb [1]. Hedge funds pay for more accurate data which us retail investors don't get visibility on.
It's over for now, but please bear this in mind when talking to people that may have lost money on this. Some people did some research, knew the risk and allocated money they were willing to lose. I learned a lot along the way, it might make some hedge funds think twice about aggressively shorting a stock, and it was just plain fun to be part of it.
