I havent looked at BFAR. I think HSYT was put on the pinks because it went 4 days without trading. I saw a post to that effect on here. HSYT often files NT10K.
I think Chinese stocks in general are trading at low p/e multiples because so many of them are scams. This one all you have to do is go to Home Depot Lowes or costco to see their products.
I think there has been one large seller sending this one down.
