IMO kerx trading pattern of the last several days indicates increasing short covering, using typical techniques they have tried to walk the price down mid-morning which has then promptly been followed by a pick-up in volume and upward price pressure. I suppose it could also be that some who want exposure peri results are choosing kerx in place of aezs out of concern that the ATM could limit short term upside. We'll never know unless we get a squeeze which would be utterly unmistakable.
I'm long here. But I never doubted that the stock would fill the gap from the ATM sell-off. Knew it would happen and expected it to on far less volume than it made the gap. The significant price area is obvious from just one glance at the daily chart. Longs want to see the mid $1.80's print on BIG volume. AEZS does that and turns that low $1.80's resistance into a floor and then we'll see what comes next. Until then however, no trade is really significant.
