However, these databases' representation of the hedge-fund universe is significantly distorted: hedge-fund managers only contribute to these databases voluntarily. Moreover, each database has a significant way to go in order to cover a sufficiently large part of the universe.
Small samples obtained by means of a non-random drawing process and extracted from a heterogeneous population lead to a significantly biased representation. Hedge-fund indices are built using these databases and therefore inherit their shortcomings. If one is to believe that hedge-fund indices estimate the average return of the total, the hedge-fund universe is thus illusory. In fact, in indices it is impossible to separate out returns from fluctuations on the hedge-fund market and the variation due to discrepancies in index construction. The latter is particularly important, as the heterogeneity of hedge funds indices reveals.
Indeed, two indices which aim to represent the same strategy can betray monthly-return differentials of more than 1,400 basis points (bp). O......................
