That is the game being played right now. Everyone dumps all their money into a few stocks, pump and dump it and move their money into the next stock that comes along. S/he who gets in early ends up rich, others poor.
I have rotated myself between TASR, IPIX, MAGS, MACE, VISG, TBUS and a bunch of others. Made money in half of them, lost money in the other half (wash sales will get me in some of them). Overall, slightly positive. Hoping to find that one stock tip which will get me in early enough.
