Sell off
I guess its some of the 28-29m exercised warrants being sold off as could be expected (some of the warrant holders are not long term investors and have made a boat load of money already from warrant exercise so are taking profit). Softness might continue for a bit until some big positive news comes out. I'm more worried if we have massive declines with cumulative volumes of 40-50m shares over a week or so but at the moment not concerned - nothing has changed in the long term investment case.
