Schiff mentionPeter Schiff rarely plugs individual miners but he referenced FR on his podcast yesterday (5/18). Not actually by name but "a silver miner that is (already) up over 4 times", clearly referring to First Majestic. In his usualy hyperbolic style, he also said that these kinds of gains would barely be noticed on a long term chart a few years from now. (Not that I necessarily disagree.)
Good time perhaps to take some profit if you got in at the low. (Due completely to blind luck, I bought my entire position exactly at the 3.50 low, something which will probably never happen again with any stock.)
But I wouldn't risk trading out your entire position. Too much potential for the silver price to break out to the next level without any notice.
