Lock quiti know that one of the reasons is that he could not sell option shares for 2 cents profit.
He must be very upset about the SP performance and could not see when he could sell his option shares (8cents) for 3 cents profit. He must be getting quite old and don't have the time to wait.
As previous NAG holder, i wish Lock all the best, no matter what he will do in the future.
PS. I don't own any NAG shares at this moment. I am currently holding some CQ.v shares and are accumulating a few other penny stocks at the prices like steal.
