Abstract

There are a variety of different approaches to benchmarking hedge fund strategies, however peer-based or manager aggregate indices remain the most widely used. Biases that exist within these indices affect the ability of an investor to fully understand the return characteristics of a given strategy. In this paper we add to the existing literature by documenting a new hedge fund index bias – High Water Mark Bias (“HWM Bias”).

Rather than being a database bias, this bias is a practical issue as result of the propensity for hedge funds to charge a performance fee, typically with a high water mark, and it describes one particular issue for investors seeking to replicate hedge fund indices.

The paper include both a empirical study of the bias using the Newedge CTA Index, and provides a theoretical framework for quantifying the HWM Bias for any index. We show the key factors to be; the frequency of rebalancing, the number of “managers” turned over within a portfolio, the average drawdown depth for the index constituents, and the future return path for new allocations.
