The most recent addition to the field approaches the problem in a different manner. Instead of reflecting the performance of actual hedge funds, they take a statistical approach to the analysis of historic hedge fund returns and use this to construct a model of how hedge fund returns respond to the movements of various investable financial assets. This model is then used to construct an investable portfolio of those assets. This makes the index investable, and in principle, they can be as representative as the hedge fund database from which they were constructed. However, these clone indices rely on a statistical modelling process. Such indices have too short a history to state whether this approach will be considered successful.
