from 2 reliable idisne sources that the WS crooks (GS, MS, JPM, etc.) buy and sell on total idisner trading (Leaked key earnings, economic data, black swan events like the S P downgrade, EU news) and only the rest of us schleps try and beat the odds using t/a. Remember about a year ago news came out that the major WS firms made windfall profits as their trading in a 30 or 60 day period was perfect, not a single loss in any of the firms during that period.
