Jimmy Cramer was on a rant tonight, saying the big brokerage houses are using their proprietary trading information to move in and out of the market. In particular , there was a huge German insurer supposedly selling large yesterday AM. When they were through, and the brokers know exactly when the last share is sold, then they step in to pick up the 'bargains'. Nothing new about this, but its a nice reminder as to how the big money is really made, the old fashioned way. Inside dope.
