From Replication to Forecasting Γ’β¬β Creating a new and active hedge fund benchmark
1) The document discusses replicating hedge fund returns through dynamic long/short trading of liquid futures using mechanical rule-based and multi-factor modeling approaches.
2) It presents fin4cast's two-stage integrated multi-factor approach to replicating the HFR Hedge Fund Index returns.
3) The authors propose going beyond replication to creating a new active hedge fund benchmark through combining return replication models with return forecasting models.

Forecasting
The replication of hedge fund returns aims:
to deliver similar month-to-month returns to a particular hedge
fund style
to replicate the statistical properties of a particular hedge fund
index
to separate the hedge fund alpha of a particular hedge fund style
from the traditional and the alternative beta
to lower cost and provide greater transparency and liquidity
to provide benchmarks for investments in hedge funds
to provide liquid underlings for structured products
to eliminate single-manager risk and style drift
to provide access for a larger number of investors

Limits of hedge fund replication β good to know
From Hedge
Fund Replication
Replication of hedge fund indices (average return of hedge funds), but NOT
to Hedge Fund
Forecasting a single hedge fund
Quality of replication vary considerably among different hedge fund styles,
i.e. Global Macro, Long/Short Equity or Market Neutral
Replication results very among different providers of hedge fund indices,
i.e. HFR or CS/Tremont
Quality of replication suffers from:
the lack of liquid instruments to replicate specific risk premia, i.e. emerging market
and M&A
the time lag to adjust the modelβs coefficients with respect to βexternal shocksβ and
regime switches
the time lag of the data availability, i.e. 15th of each month
the low frequency of the available data, i.e. monthy returns
the short history, i.e. just 167 data points since January 1994 for CS/Tremont Hedge

Building of forecast models to predict the direction of the

Combining the results of the forecast models with the results of
the replication models by adjusting the modelβs coefficients:
if the return forecast is positive the coefficients stay the same as
for the replication model
if the return forecast is negative the coefficients are multiplied
by -1
The objective is:
βΊ to create a new and active hedge fund benchmark
βΊ to out-perform the average of the hedge funds by generating
positive returns during periods of negative returns of

How to replicate?
Replication of CS/Tremont Hedge Fund Composite Index using fin4cast two stage multi-factor
integrated Hedge Fund Replication Approach
Good to know:
Replication works for average hedge fund returns, but not for a single hedge funds
Replication quality varies among differnt hedge fund styles and index providers
Replication lags behind due to time lag of the data availability and adjustment of the modelβs
coefficients
What are the results?
βΊ Our results give strong evidence that the synthetic hedge fund portfolio is able to replicate the
statistical properties of the monthly returns of the CS/Tremont Hedge Fund Index with respect to
the month-to-month return and the standard deviation
βΊ Our findings show that the compound alpha of the CS/Tremont Index compared to the cost and
interest rate adjusted returns of the synthetic portfolio is negative
New idea about an active hedge fund benchmark was born:
