Zeev, re: mainehiker's little bios (from a slightly diffeent perspective).
I've been following, and learning to trade, 6 of them (ARIA, CRIS, DNDN, GERN, INGN and ONCY) for about 9 months. I've had good results with all except GERN, which has been a water treading experience thus far.
My experience has been that they are terrific swing traders, often giving significant profits (~5-10%) in a matter of days. They often make violent and completely unpredictable moves, but do not always offer intraday opportunities. Of course, I'm not so quick as some at taking advantage of that last.
The trick I've learned about them, as I'm sure I don't have to tell you, is to buy right and be patient.
regards,
