A Suggestion for Remedying the Overstated Performance of Non-Investable Hedge Fund Indices

Investable indices tend to recursively underperform their non-investable versions. In light of recent events, we can wonder whether the liquidity crisis that occurred in the wake of the Lehman collapse and had a significant impact on the performance of hedge fund strategies (more particularly on the strategies that are exposed to credit risk) has increased this excess return or not. In this respect, it would be interesting to compare the excess returns of non-investable indices and those of their investable counterparts before and after 2008.
