Spatial Dependence in the Hedge Fund Returns

We apply an exploratory spatial data analysis framework for integrating the time series of hedge fund returns to its neighborhood, mapping, and local analysis for the feasible spatial modeling. By comparing the classic risk factor analysis of hedge fund performance of ordinary least squares regression with spatial autoregressive models, we investigate each model¡¯s respective ability to produce fair estimates of risk-premiums per hedge fund styles. The time series analysis of hedge fund returns from the Barclays Hedge indicates that, for some of the sub-investment styles such as equity long-short, equity long-bias, event-driven arbitrage, convertible arbitrage, fixed-income arbitrage, distressed securities, multi-strategies, and commodity trading advisors, the spatial autoregressive modeling may provide consistent estimates of factor risk-premiums by correcting spatial dependence through the measure of endogeneity of implied volatilities. The spatial specification employed here includes spatial lag (SLM) and spatial error (SEM) models and also applied to a relatively short time series of a failed credit hedge fund previously marketed its vanishingly rare talent of return predictability and consistency. Both SLM and SEM models used to explore some practical implications in an ad hoc screening through the missing spatial autoregressive heterogeneity in the ordinary least squares approach.
