The Fear Index – if you’re a Wall Street algorithm and you’re five microseconds behind, you’re a loser.

Robert Harris’ latest book, “The Fear Index,” stars a hedge fund driven by an algorithm run wild. In researching his book he went to observe a hedge fund in London. Basically it was a room full of computers and in the course of 20 minutes he watched one computer made $1.5m by itself. The interview below with Paul Solman of PBS is quite revealing when you consider the lengths that some will go to get a competitive edge on their opponents. In the book they develop an algorithm that can predict the markets by analysing the incidence of fear-related words on the Internet, trends on Facebook, Twitter, the sense of a mood. Although Harris thought that this was original he subsequently found out it has been going on for sometime. Bloomberg News feeds are digitalized and go straight into the machine, and buzzwords are picked out, “panic, rumor, fear, slump.” A few milliseconds could be the difference between success and failure in the markets.

The extent that these traders will go to in extreme. In the U.S., high-frequency firms represent only 2 percent of the 20,000 or so trading firms operating today. But they now account for nearly three-quarters of all trades. And the average time a stock investment is held these days is 22 seconds. If time is money, microseconds are now millions. In a recent TED talk on cutting-edge technology, tech whiz Kevin Slavin wowed the audience by describing buildings now being hollowed out in Lower Manhattan. Why? So that high-frequency trading firms can move in and get as close as possible to New York’s point of entry for the Internet at a so-called carrier hotel in Tribeca.

Just to give you a sense of what microseconds are, it takes you 500,000 microseconds just to click a mouse. But if you’re a Wall Street algorithm and you’re five microseconds behind, you’re a loser.

    To me this says be a long term investor. Trading is a zero sum game. For every winner there is a loser. In fact trading short term is simply gambling and as such is a terrible drain on any economy as it adds nothing useful.

    Agreed – the issue I have about CDO’s and CDS’s is that there is no value
    generation and the income is derived from actually creating nothing. Have you watched the movie – Inside Job? Well worth a look.
