While I was reading the information on these separately managed accounts I came across an interesting performance statistic - down capture ratio and up capture ratio. These statistics are the fraction of the market gain a manager captures in months when the market rises and vice versa. It is easy to compute in an Excel spreadsheet. The Aletheia Large Cap Growth Managed Account reports an up ratio of 1.65 and a down ratio of 0.47. This is a very impressive asymmetry. According to Alexander Ineichen, asymmetric returns are the hallmark of hedge-fund like performance. So of course I computed my ratios for the last 36 months: 1.22 up and 0.71 down. Not bad. It wasn't always that way :) The asymmetry is increasing over time. In my early days of investing the asymmetry went in the opposite direction!

Following my discussion yesterday with Rich Gates and BackOfficeMonkey (love the handle!) I took another look at the correlations of my returns (since October 2002) with several other assets and managers. As I knew already, my largest correlation is with the MSCI World Index. I have a small negative correlation with the TIAA Bond Market Fund and a small positive correlation with the Australian Dollar. I estimated a regression against all these factors and only the beta on the MSCI World Index was statistically significant. If I had the data to hand I'd do a more sophisticated analysis, but the point is that the MSCI is not a bad benchmark.
