The longer we go without news, the more the market seems to repond as if news is not likely to be coming anytime soon. Recent tax loss selling may have put some downard pressure on the stock price heading into the end of the year, but now that tax loss selling is no longer a factor, the only reason for low/lower share prices (in the face of rising prices among some other explorers) is failing confidence in near term progress.
Please note, however, that any opinions regarding the future direction of this stock are largely meaningless when looking at exceptionally poor trading volumes. In my opinion, then, any news could - could, not will - bring in the kind of volume that causes the PPS to break strongly in one direction or the other. ...could even be something out of left field.
