Research Purpose

1. Comparative time series analysis of Fund of Hedge Funds vs. Single Manager Funds

2. Estimating the impact of leverage on downside volatility and risk

3. Constructing style indices from risk parameters and AUM weightings

4. Automating data import and data analysis for future quantitative analysis (‘dashboard’)

Code Execution (1/2)

Data Import •Extract relevant data from Access (SQL)•Import data as Pivot table report

Data Treatment •Test for serial correlation / normality•Calculate adjusted excess returns

Data Analysis •Select funds with consistent data series •Determine fund specific risk parameters

Code Execution (2/2)

Weighting •Estimate weighted average parameters•Construct style indices

Comparative Analysis •Calculate within-group variation•Calculate between-group variation

Data Output •Tabular display of aggregate results•Construction of line - bar charts

Significance

Empirical Findings (1/2)

• Measures of volatility and downside risk were significantly improved for FoHFs, compared to their single-strategy peers

• No evidence was found that FoHF strategies overcharge for risk diversification benefits

• With reference to continuous drawdown, attrition rates and VaR, FoHFs are a valuable supplement to the institutional portfolio

Empirical Findings (2/2)

• It could not be established whether gearing affected hedge fund performance – either favourably or adversely

• Some statistical evidence could be found of a higher exposure of leveraged funds to the recent subprime crisis

Extended Research

• Hedge Fund Linear Pricing Models– Sharpe Factor Model (Sharpe, 1992)– Constrained Regression (Otten, 2000)– Fama-French Factor Model (Fama, 1992)

• Factor Component Analysis (Fung, 1997)• Simulation of Trading component (lookback
