Bag-holders hoping to recoup losses on anyone dumb enough to buy.
This stock is for traders only who plan on selling very quickly (24-48 hours) on upside moves.
The stock is broken as is the company. It struck out once with Synavive earlier this year; struck out again when Z160 did not pan out; then with Exalgo going 100% generic next May, that will be the third strike.
IMO, money will drop the floor out of ZLCS when it fails to get any new funding for Z994.
While there could be some good news on the horizon in 2015, SYN possibly, maybe, kinda-of, putting some money into more development of Big Red, however, ZLCS will probably be BK by then, so, that news won't help.
I see there has been no law suits filed against ZLCS since the R-S which indicates that there probably is not much money in ZLCS coffers to pay the lawyers fees, filing fees, etc., or, maybe there are no grounds for a suit?
