they could however, it is most likely not going to come out early, this is only wishful thinking of which you hope it could happen because you want the pps to go up quicker. Unfortunately the way in which to expose the short position is not an overnight operation, thus why it is taking longer. Patience upper, the shorts will get what is due to them, but as the saying go, slow and steady wins the race.
My advise is to not look for this covering every day... It is still min a month a way.. Which is well worth the wait, however if you look for it happening every day you will get frustrated, in the mean time further the pps will fluctuate. Do not fall victim to the belief that many have that the stock is going to go straight up forever, as profit taking will happen and we will have red days ahead. Overall though the trend is remaining up.
hope this helps.
