First, this is probably done by hedge funds in NY [or the Cayman Islands]. I am guessing that Soros is not involved because it is not his style, actually. His investment style is to let things get way out of wack because a lot of people have stampeded in a heard mentality and gone way too far, and then try to time the market turn and bet on the correction. I know Soros is despised around here, and I don’t like his politics, but there has been a method to his investment madness.
I heard London or Dubai but there's lots of wild rumors raging.
