World Cup Forecasting Challenge For Quants 111

Posted by timothy from the kickoff-in-four-days dept.
databuff writes "As a break from projecting the strength of subprime mortgages, credit default swaps, and other obscure financial instruments, quantitative analysts at Goldman Sachs, JP Morgan, UBS, and Danske Bank have modeled the 2010 FIFA World Cup. Now Kaggle has set up a forecasting competition, allowing statisticians to go head-to-head with these corporate giants. The challenge is to predict how far each country will progress in the tournament."

    For the record, quants rarely try to predict things in the market. That's left to people who work in econometrics. The main job that a quant does is to price financial instruments in a way that is consistent with the market prices of other liquidly traded assets. I'm being deliberately vague about what precisely is meant by "consistent" because that often depends on the choice of model, but there are also model-free results which require certain asset prices to obey certain relations: put-call parity [wikipedia.org], for example.

      I'm not sure the distinction you are using. Quants predict nothing. They are used to see which companies appear undervalued, and thus would be good values (and not in the sense of a value vs growth company). They are also used to determine which appear overpriced. Then, if you hold shares in an overvalued stock, you sell it and buy the undervalued one. Of course, Google has perpetually be "overvalued" even while rising in value greatly

        I think that's more like a financial analyst. A quant typically works one level of abstraction away from the stock market itself, calculating prices and hedging strategies for stock options or credit default swaps, say.

        I know there's a lot of anti-quant sentiment around at the moment, and this being slashdot, I'd like to add a disclaimer: I'm just trying to describe the job that a quant does in theory.

So they can tell you, statistically, what losses may be incurred on an asset in a given time frame or how you should hedge the risks attached to a complex financial security with simpler, more liquid securities. Now, of course quants can't predict the future, but they can (or at least should be able to) prepare you for future eventualities by assigning future eventualities with a probabilistic d

    15 years ago, when I was working as a Systems Analyst at a Brazilian bank that shall remain nameless, it was common knowledge that trading desks all over the country were engaging in this kind of thing. They would create "financial products" tied to World Cup statistics and use all the technology, corporate and individual knowledge at their disposal to try to predict the outcomes and win or lose huge sums of money. Individuals bet with their own money and the corporations they worked for (and who provided the infrastructure for this) tended to look the other way. One such "product" I remember well was the so-called "GDC" ("Gols Da Copa" - Cup Goals) which created a market around the total number of goals to be scored during the World Cup. I knew one trader who payed for his house with his GDC money. Most of the time it was a mostly harmless hobby (if you discount the fact that gambling is illegal in Brazil) but as the World Cup final approached, I was very aware that the resources who were supposed to be working on models of commodities, foreign exchange and other markets did little else than model the World Cup; this included both people and computational resources. I wonder if some of my old colleagues in Brazilian banking ended up finding positions in Wall St.

    • I would think that if I were running an investment bank I would encourage my employees to engage in this sort of behavior - use company resources, but not funds. I think this sort of thing would make for remarkably good training for predicting actual financial markets.
