|Eurekahedge and Mizuho-DL Financial Technology partner on new hedge fund alpha ranking|
Eurekahedge and Mizuho-DL Financial Technology have partnered to deliver a customised alpha measure. The Eurekahedge Systematic Alpha (ESA) runs on a fund level across the entire breadth of the Eurekahedge Global Hedge Fund Database.
The ESA statistic is a systematic approach to measuring the excess returns or alpha of a hedge fund, and is available for display on individual fund factsheets on the Eurekahedge platform as well within the multitude of Eurekahedge hedge fund databases.
As part of the roll out of the ESA statistic on a fund level basis, Eurekahedge will through its proprietary methodology identify and short-list the top ranking alpha funds as potential constituents for the new Eurekahedge Systematic Alpha Hedge Fund Indexes .The Eurekahedge Systematic Alpha (ESA) methodology is as follows.
|Accessing Alpha, Subsidising Alternative Beta: The Appeal for Investors|
In recent years, academic empirical studies have shown that representative hedge fund indices can be replicated with some stylised, tradable systematic risk factors at the range from 40% to 80% of the risks (variances) of the indices. This implies that a part of hedge fund returns can be captured through systematic exposure to various risk factors, the range for which has varied across empirical studies on the following accounts:
Despite the aforementioned challenges, it has been concluded based on empirical research coming out of these multi-factor regression models that hedge fund returns can be decomposed into traditional beta, alternative beta and the residual or unexplained portion – the manager’s alpha.
However, given the nature of actively managed investments such as hedge funds, not all sources of excess returns can be replicated with tradable risk factors. This implies that alpha which may be attributed to the manager’s skill could very likely be that portion of alternative beta which cannot be effectively modelled or replicated.
Despite this limitation, a systematic approach to quantifying alpha offers investors the opportunity to identify and access hedge funds with exotic sources of returns that would help diversify their portfolios. Furthermore, the prospect of successfully modelling a hedge fund manager’s systematic drivers of returns (i.e. alternative beta) gives investors the opportunity to access a part of the fund manager’s return at a lower cost through either replicator indices or via synthetic products.
With this in mind, Eurekahedge has launched the first of its kind ‘pure alpha information’ on a fund level across the entire breadth of our hedge fund database covering all geographic and strategic mandates. This information, as captured by the Eurekahedge Systematic Alpha (ESA) statistic allows investors to identify, rank and compare individual hedge funds based on their ability to deliver excess returns or pure alpha.
The Eurekahedge Systematic Alpha (ESA) utilises multifactor regression analysis against seven pre-specified common risk factors to assign an alpha value to individual hedge funds based on the manager’s ability to deliver returns in excess of the systematic risk factors modelled. The constant term in the regression analysis is recognised as the ESA statistic for an individual fund.
The seven risk factors consist of
Returns are regressed against the specified risk factors over a 36-month period to assign ESA values to individual hedge funds.
Based on the ESA values, funds are subsequently ranked across the breadth of the Eurekahedge Global Hedge Fund Database.

|Limitations – The challenge with a systematic approach|
As the first of its kind systematic approach to assigning alpha values on the individual fund level basis (as opposed to the more ubiquitous index level analysis), the ESA statistic’s investor friendly appeal should be viewed with caution for some of the main reasons listed below.
Table 2: A systematic approach to quantifying alpha has limitations
ESA rankings; which are intended as a guide towards identifying managers with exotic sources of alpha, should be viewed in relation to the manager’s full track record, and are intended more as a helpful guide to the manager’s recent performance against common market risk factors, as opposed to a seal of approval (or disapproval) on their ability (or lack thereof) to deliver excess returns.
