FEINBERG JEFF most probably sold all of his shares!
I believe the primary seller, FEINBERG JEFF, of the huge blocks during the previous week sold all of his shares.
During September 10 he sold 1845069 at $1.03 and 815000 at $1.09, allowing him to remain with 1,623,507 shares. If one notices the slight volume decrease after the huge sell of during the 10th, then such a conclusion might be safe; sell of the remaining 1.6 million shares is more than possible.
