It is possible the steady slide down has something to do with the merger. There seems to be a lot of uncertainty in the market as to whether it is going to happen or not. But it may also be a bit bewildering when companies like KDR Kidman resources & LPI Lithium power finds a bucket load of lithium and the SP rockets to within a whisker of a company that is producing. Go figure.
I would say some money has dropped off GXY and gone onto some of these other Lithium players for now.
One may also conclude that GXY is being manipulated for the purpose of accumulating until this merger is completed then it may continue on its way to where it should be. Possibly shorters having there last feed before the merger is signed off also.
whatever it is I will wait patiently until the tide turns, Not long now.
