I don't know PON well enough to compare RAY and PON..
I do know RAY with its potash holdings,share structure,cash on hand,debt load and management team is an excellent buy at this level..
I say nothing about it's other properties..big iron and uranium properties,both well worth todays share price alone..
I never give targets or say when to sell...just what I am buying...
But I did buy a big batch of RAY at $1.65 .....long after a bigger batch at under .50....so am in for the long term..
I don't play for pennies..and am always selling at least double on my top buy price..sort of a little formula I use to sell..but never shoot a running horse either..
Never lose money that way..
