Yes, funds/analysts know they can manipulate Chinese stocks, but not American stocks. They know they can get info from company from briefings, so they can make money from that. Imagine, the former chair of GS leaked info.. this is going around long enough, just who's getting caught first?
How can one research dept from one trading firm talking down one stock while another investment group from same trading firm own lots of shares? Bias is all around.
But I know one thing SOLAR will come around. Very low PE. Real earning.
