Related: About this forumRaging Bulls: How Wall Street Got Addicted to Light-Speed Trading
Wall Street used to bet on companies that build things. Now it just bets on technologies that make faster and faster trades.Editors note: One of the most interesting things about the catastrophe at Knight Capital Groupthe trading firm that lost $440 million this weekis the speed of the collapse. News reports describe the bulk of the bad trades happening in less than an hour, a computer-driven descent that has the financial community once again asking if their pursuit of profit has lead to software agents that are fast, dumb, and out of control. Were posting this story in advance of its publication in Wireds September issue because it examines how Wall St. got to the point where flash failures come with increasing frequency, and how much farther traders seem willing to go in pursuit of ever-greater speed.
The 2012 New York Battle of the Quants, a two-day conference of algorithmic asset traders, took place in New York City at the end of March, just a few days after a group of researchers admitted they had made a mistake in an experiment that purported to overturn modern physics. The scientists had claimed to observe subatomic particles called neutrinos traveling faster than the speed of light. But they were wrong; about six months later, they retracted their findings. And while special relativity upheld is the worlds most predictable headline, the news that neutrinos actually obey the laws of physics as currently understood marked the end of a brief and tantalizing dream for quantsthe physicists, engineers, and mathematicians-turned-financiers who generate as much as 55 percent of all US stock trading. In the pursuit of market-beating returns, sending a signal at faster than light speed could provide the ultimate edge: a way to make trades in the past, the financial equivalent of betting on a horse race after it has been run.
Between the time the first paper came out in September and last week, a guy in my shop had written two papers explaining how it could be true, a graying former physicist said ruefully, sipping coffee near an oversize Keith Haring canvas that dominated the room at Christies auction house where the conference was held. Of course, youd need a particle accelerator to make it work.

(793 posts)1. The Salkind Superman movie came on a few weeks ago...
...with Christopher Reeves, Margot Kidder and Gene Hackman(oh, and Marlon Brando!). For its age it was a great film to grow up with. This article had my thinking about that scene where Superman, failing to save Lois Lane from Lex Luthor's nuclear-induced mega-quake, flies around the planet at light speed to reverse the earths rotation and time with it, bringing Lois back to life.
The Higgs Boson discovery may open the door to anti-gravity and who knows what. Perhaps we will learn how to alter the past or live to be 5,000 years old. And with such possibilities, these quacks hope to acheive the glory of wringing a few more bucks or a million out of the market. Thats their aspiration if given the "Fire of the Gods"? What losers!
