The Joys of "Flash Trading"
from Rolling Stone magazine, March 4, 2010:
"Say you're working for the commodities desk of a big investment bank, and a major client — a pension fund, perhaps — calls you up and asks you to buy a billion dollars of oil futures for them. Once you place that huge order, the price of those futures is almost guaranteed to go up. If the guy in charge of asset management a few desks down from you somehow finds out about that, he can make a fortune for the bank by betting ahead of that client of yours. The deal would be instantaneous and undetectable, and it would offer huge profits. Your own client would lose money, of course — he'd end up paying a higher price for the oil futures he ordered, because you would have driven up the price. But that doesn't keep banks from screwing their own customers in this very way.
The scam is so blatant that Goldman Sachs actually warns its clients that something along these lines might happen to them. In the disclosure section at the back of a research paper the bank issued on January 15th, Goldman advises clients to buy some dubious high-yield bonds while admitting that the bank itself may bet against those same shitty bonds. "Our salespeople, traders and other professionals may provide oral or written market commentary or trading strategies to our clients and our proprietary trading desks that reflect opinions that are contrary to the opinions expressed in this research," the disclosure reads. "Our asset-management area, our proprietary-trading desks and investing businesses may make investment decisions that are inconsistent with the recommendations or views expressed in this research."
Banks like Goldman admit this stuff openly, despite the fact that there are securities laws that require banks to engage in "fair dealing with customers" and prohibit analysts from issuing opinions that are at odds with what they really think. And yet here they are, saying flat-out that they may be issuing an opinion at odds with what they really think.
To help them screw their own clients, the major investment banks employ high-speed computer programs that can glimpse orders from investors before the deals are processed and then make trades on behalf of the banks at speeds of fractions of a second. None of them will admit it, but everybody knows what this computerized trading — known as "flash trading" — really is. "Flash trading is nothing more than computerized front-running," says the prominent hedge-fund manager. The SEC voted to ban flash trading in September, but five months later it has yet to issue a regulation to put a stop to the practice."
