I can't say for sure but I think it has to do with the fact the market doesn’t trust Chinese Micro / Small cap stocks. I read a news article some time ago about that.
I owned this company a while back and took a real beating bought way to high. Just a thought if Chinas economy is going so strong that they have to raise interest rates and CPSL is not moving? I owned CPSL CDII CIIC CSGH and others.
My self I stay away from I’ll say most of China stocks .
