I don't think this it the time to give up. The same boots-on-the ground sleuthing that finds frauds (LPH et al) also finds growth (CLNT)...so there's legitimacy out there. In addition, just read today that GSCO is expecting big China growth this year, which should bode well for legit businesses. I don't think i'm sophisticated-enough of an investor to know what's a fraud and what isn't, and i've surely been around long enough to know the risk involved. but i also know the reward - and it's excellent, and has been excellent. When traders/investors stop reacting to seemingly legit catalysts, that might be the time to hang up the cleats.
Solid DD combined with timeliness and conviction is a recipe for profits.
