Does anyone have access to recent, good quality research on this company. I made the mistake of buying in too high, quite some time ago and need to make a decision on whether to hold or cut my losses. The sp is improving now at long last but what is the upside potential? It is pretty obvious that the POG is critical but in the last big run up, NEM didn't perform that well so other factors (e.g. mines in third world countries or poor management) must be at issue.
