Norway is not what you would call a hotbed for hedge funds. Due to restrictive regulatory requirements and an almost uniformly long-only focused investor-community, there are only a handful of hedge funds managed out of Norway.

Despite this, Norwegian Warren Short Term Trading (WST) is one of the best performing hedge funds in the world. Since the fund’s inception in November 2011, its return has been 46.7% with a net 2012-return of 29.1% after fees (pdf).

WST hedge fund manager Peter Chester Warren explains how this works:

Our hypothesis is that most of what happens in the markets during a single day is noise created by orders, rumors and other temporary influences and that there is no informational value in this. Unlike our other funds, we do not try to separate the signal from the noise in WST but accept it for being just noise. … Time is instead spent on creating mathematical and statistical models meant to uncover short-term human behavior.

This is a significantly different strategy than that of most other hedge funds, which typically own assets over a period of time. WST rarely owns assets longer than a few minutes or sometimes even a few seconds.

And every day when the asset manager goes to sleep, he holds zero assets. Then, when he gets back in to the office the next day, he starts from scratch again, looking for tiny opportunities in the markets using a combination of correlations, math and experience. (more…)
