IMO. The MMs knowing the PPS would go up with pending ELI-216 Patent Grant publication, heavily Naked Shorted the market the past 16 days and with prior arrangements to buy Trellus shares Covered the Naked Shorts. The MM made money (1)with the Naked Shorting and (2) sale of the Trellus remaining shares.
The sign was given premkt to all the MMs when the B/A was flashed at $0.14/$0.15 even though the previous day close was $0.168
