Glen, it's relative since we're talking about the battery industry only, specifically Chinese battery industry. Turns out that CRTP has a niche within that industry, environmentally friendly lead-acid batteries. But if we were to lump the China battery makers together, it would simplistically look something like this:
CBAK PE=yeah right
AONE PE=yeah right
ABAT PE=13
HPJ PE=17
CSGH.OB PE=9
CRTP PE=11
CSGH is interesting, but they get the OTCBB penalty on their valuation. One might wonder why CMTP isn't listed; they don't do batteries, so they're a little peripheral in my mind. So there you have it; 4 good ones and two suspect ones.
Solid DD combined with timeliness and conviction is a recipe for profits.
