…Goldman Sachs has been caught at another racket in the stock market: front-running trades. What a clever gambit, done with the help of the markets themselves – the Nasdaq in particular – in which information on trades is held back a fraction of a second from public view, while the data is shoveled to the computers of privileged subscribers who can execute zillions of programmed micro-trades before the rest of the herd makes a move. This allows them to vacuum up hundreds of millions of dollars by doing absolutely nothing of value.
