I set my son up on a virtual trading platform, and he does quite well with it (better than I do, ugh). I told him to keep an eye on RENU, but according to his opinion, "it's not time yet".
He's played a few stocks where he has done very well, consequently, they are now on my "watch" list..... (pretty sad when you're taking investment advice from a 14 yr old.......)
Anyway.... time will tell. Know what you hold, hold what you know. As soon as "what you know" changes, it's time to get out. (Put here for my own sake, as much as anyone else's.....)
Best of luck.
