GRZ made a new 52w low yesterday and again today. KRY is just a mere .13 above its 52 week low and to be honest I think at this point we will see it at least tested before we go up.
But what has changed with GRZ? With KRY? Nothing. When fundamentals or a catayst situation diverge from price it is a time to buy and be patient. We have more positive movements re: permit than we did when KRY was valued much higher and gold was much lower. Eventually this will equalize out.
If you do not believe the catalyst/fundamentals present a reward/risk that is acceptable, then you should sell. Otherwise, hang on and try to use the movement to offset losses.
