The share price decline has been steady but continuous. I've thought several times about getting into this but right now I wouldn't touch it personally until we find the reason for the fall.
There's usually someone in the know with these things and they may have been disposing of stock gradually before the bad news hits. On the other hand it may be as you say just selling due to lack of interest and no newflow. Time will tell but I've lost money on falling knives before and now prefer a little upward momentum before buying in.
