Don't know if there will be a "short" squeeze or not but I do agree that the float is getting smaller.
I have been watching for a definite proof of a short squeeze but never really seen it. If it exists, it does not last long.
Go back and check ICPT, went up like crazy from the 50s to 400s,500s. Was there a big short % ? if yes, then there is proof of a short squeeze.
