EVALUATING HEDGE FUND INVESTMENTS: THE ROLE OF PURE STYLE INDICES
Francois-Serge Lhabitant

INTRODUCTION

Lhabitant joins the quest for a sound method to use in evaluating risk in portfolios of funds. He finds attractive the use of a small number of risk drivers (“factors”) in order to reduce the complexity of the task. Like other authors he proposes a linear factor model (a linear regression) to identify the risk drivers. Since there is ample research demonstrating that hedge fund returns have option-like (i.e., nonlinear) features, he proposes using as candidate factors, variables that are known to be nonlinear functions of more primitive risks. The natural set of candidates then are hedge fund style indexes.

Lhabitant then illustrates how this estimation approach can be used to compare a hedge fund’s stated approach to the styles that actually explain the fund’s returns. This technique might also be useful for evaluating style drift, a risk which is particularly difficult to monitor for hedge fund investors. This approach also suggests which index benchmarks might be most useful for evaluating performance. Finally, this approach provides a coarse means for an investor to establish (or verify) that their hedge fund portfolio effectively contains a diversified set of styles.

Lhabitant suggests that VaR could be calculated for any fund or portfolio of hedge funds even without the benefit of obtaining position information from the managers. First the VaR of each of the style factor indexes is calculated. The fund VaR is composed of two (appropriately combined) elements. The first element is in effect the VaR of a portfolio of style indexes, with weights provided by the funds betas with respect to each style. The second element is the VaR of the fund variance that is unexplained by the style factors.
