The size of the short position is so big in relation to the float I would be very nervous if I were short. After the reversal yesterday, the volume has collapsed. This could get extremely illiquid as we approach quarters end. After that, you are looking to new quarter where people will be looking to accumulate for the distribution. I predict this could begin the new quarter with quite a sharp rally, perhaps as high as $15.
IMO will need to break through the 20dma of around 14.60, Thus should make for a great short squeeze to the 50dma 16.97, breaks through that and the sky's the limit. I'm looking for this to happen over the next few weeks. 16.97.....seems like no problem
