Interestingly, when Soros was a partner with Jim Rogers, Soros was the trader and Rogers was the strategist. So I don't know how much he knows in the conventional sense and how much is inside information.
Soros knows how to move markets for profit. If he is doing something publicly it is most likely because he wants to capitalize on the counter move. Just look at what he did to the British pound in the early 90's.
