Nickel just bounced up .7% in any case. In terms of determining a point to exit a stock it seems like common sense to be looking at everything that is going on as much as possible - price, production rate, number of shares, management, amount of resource and weigh it all up.
At present you would be mad to sell agm imho. A bit of a distraction from discussions of dwecke's holiday prospects anyway lol
