You can get more the 100% without naked shorts, sure, but is that legal?, does SEC allow that?, nobody is concerned that if there is a short squeeze there is no chance in hell to close out? (like we are seeing here)
The point I tried to make was - this short was done to drive price down to zero (it can do that with that large of a position) in collusion with negative media reports from friends... That is manipulation. And they got caught with their pants down.
I'm also not convinced on no naked shorts, we'll see...
As for robinhoods closure of trade, they only disabled buy, not sale... as for reason, are you speculating? I did not see any clearing house comment. This was brought up by Cuomo as well in interview.
As for illegal on robinhoods part, we'll see, there will likely be an investigation. Especially since they are owned by the company that bailed Melvin Capital out.
