I have not touched GDN this year, but I keep them in my watchlist. Maybe its because they seem to be the most talked about stock on hot copper.
I think you should hold because the price will go back up. In any GDN thread there is an army of mindless rampers. I'm posting as a genuine disbeliever in GDN, but I think if you sell now you will have bought at the high and sold at the low. And the price will rise again as it always has.
Good luck
