I know this author's work well, he does not post short calls often (every few years at most), but when he does, look out!
His last call was a short squeeze on LOCM about 4 years ago and it went from $3 to $13 within a few days.
That he is calling this the most highly leveraged short squeeze as a percentage of float that he has ever seen tells me the party's over for the easy short money here. I'm getting on board for this one, should be fun.
