BAU has had flees for a loooong time. It has traded well below cash backing for an eternity and there are a lot holding that purchased in the late 20 c range and quite a few in the 30's.
It deflies belief that it could trade so far below cash backing but it has and one must.... ask why is this so ? As the great professor would say.
On numerous ocassions of more recent times it has had a little spurt only to be sold into, needs some real volume to make this baby sing. For those fortunate to have picked up a few at 10c they are in the money but also in the minority.
