It has nothing to do with being a great stock picker, it's precisely because in the last 12-18 months stocks have been hammered so low that they're trading at bargain discounts. A little bit of good news for the few that are worthwhile do huge things to those stocks. The same should happen to CUU, but the idea that because they were hammered so low that other companies that have had successful drill results, PEA, PFS and BFS's haven't also soared is silly. Plenty of companies made great returns for those who bought in the weak market before good news came out. There have been plenty of upsets as well, but even with those many traded to ridiculouslu unsustainable low levels and would have given you a nice return if you bought when it started to show strength again.
I'm sure there will be plenty of opportunities when CUU does eventually pay out, the question is if there will be more or less; and ones that you've identified yourself.
