It's now three month's since we started trading a portfolio designed to replicate the performance of hedge funds by picking those stocks with maximum exposure to the dynamic trading risk factor.
The portfolio's performance peaked in early August, and has been in a drawdown since then. It was hit hard on the 1st. September, when all the financial stocks dramatically underperformed the market. However, it is still profitable after fees.
UPDATE 03/15/2010: The performance chart has been replaced with the one for this current year. As you can see, the system is currently in a small drawdown.
