I don't know for sure, but I do know it started trading with out any Market Makers!!! Sort of like a gray sheet stock might. Frankly I trusted it more because there were no MM's to manipulate the damn thing, just buyers and sellers!
The caviat emptor means little me. I have seen stocks rise from the dead, and others crash from the heavens of NASDAQ so I am not sure it really means that much more to tag it onto to old news.
I did not buy a lot of shares, but I bought them cheap, and figured I would just set them aside for a few years and see what happens. I owner 3 or 4 other china stocks like it, and like buying shares it what looks like short and bear mauled bloody shares, that have a real business and real revenue, etc.
I do know it has sold recently at prices that are least twice I paid for my little stash of shares.
