Definition of Research Problem
Question 1:
Do risk measures derived from Sharpe‘s Capital
Asset Pricing Model and Modern Portfolio Theory
adequately display the risks of Alternative
Investments?
Question 2:
What risk measures more accurately reflect the
inherent risks of Alternative Investment Portfolios?

Statistical Analysis
Naught Hypothesis:
There is not sufficient statistical evidence that traditional risk
measures derived from Sharpe’s CAPM and mean-variance
analysis adequately reflect shortfall and default risks of nontraditional investments
Alternative Hypothesis:
There is sufficient statistical evidence that Sharpe’s CAPM and
mean-variance analysis adequately explains the inherent risks
of non-traditional investments
It is the aim of the research study to show that H0 is indeed
true.

Statistical Analysis





To evaluate the two hypotheses, the following characteristics
of Hedge and Private Equity Funds will be studied in detail:
Skewness of probability distributions and the likeliness of
extreme results (default risks)
survivorship bias and the exclusion of sunk funds in existing
surveys
managerial bias and the impact of fund manager skills on
the risk dimensions
shifts in market correlations due to unforeseen events
short performance history and statistical inference from
limited sample sizes

Distribution of Returns
Use of Derivatives and Hedging
Instruments
Unbalanced Allocation of funds
between Equity and Bond
markets
Financial Leverage to enhance
performance from Arbitrage
Trades


Lower degree of overall
variation in performance
history

Alternative Investment
Funds return distributions
display excess kurtosis
and are negatively skewed

Higher risk of returns to
fall significantly below the
expected mean (‘Fat
Tails‘)

Effects of Autocorrelation
Effects of Managerial Bias and
Performance Smoothing
Survivorship Bias and the
exclusion of sunk funds

Distribution of funds
returns appear smoother
than they actually are

Performance of Alternative
Investment Funds (entire
industry) appears better
than they actually are 
Industry Indices
Other effects of Autocorrelation

Changing Market Correlation
Disruptive market events can
significantly change the
interrelation between market
and single investment/Portfolio
Alternative investment funds
tend to be more susceptible to
disruptive market events

Beta may be an
inappropriate measure of
risk in the event of
changing market
correlations

Adapted Beta measures
may improve the
assumptions derived from
the CAPM
Beta fails to reflect risks of
investments over the long-term

Statistical Inference
Short Performance History of
Alternative Investment Funds
Inappropriate Levels of
Confidence in Statistical
Inference

Limited degree of usability
of time series analysis

Accuracy of simulated time
series

Analysis of Fund of Funds
or Style Indices leads to
biased results
Limited availability of data on
Hedge/Private Equity Funds

Proposed Analysis Framework





In order to provide Analysts and prospective investors with
a holistic risk analysis framework the study will…:
Try to evaluate how existing risk measures can be adapted
Provide analysts and investors with innovative measures to
assess risks
Estimate in what domain and under what circumstances
those risk measures hold true
Evaluate what risk measures should be assigned to what
alternative investment strategies
Assign weightings to risk measures according to their
relevance
Adapted risk measures will be subject to the same statistical
analysis as traditional risk measures
