I agree - I may be wrong but it appears that most of the short selling occurs during the first and last 30 minutes of trading, and before/after hours. To me, that's a sign that their influence is weakening. The share price is so artificially low that there's very little room for it to go down which means there's a considerable risk for the shorts to stay much longer. Don't forget they still have to cover in order to buy more shares to short, and at this level - why take on the additional risk.
