Radian legacy business is still a hole and no one knows how bad it will be, because it depends on so many factors. So it is quite normal that institutional buyers are waiting on the sideline and obviously short sellers are taking it all over. $2.5, $2.2, $2.0, $1.8, are all foreseeable. On the flip side, $3.0, $3.5, $4.0, $5.0, $8.0, $15.0 could also become reality if Europe takes on expansionary policies and US keeps pumping up its economy with QE tricks.
This stock is purely a gamble. Make your bet and don't complain, just like what you did in a casino in Vegas.
