Weaknesses of models used to analyse Hedge FundsWeaknesses of models used to analyse Hedge Funds
Models currently used to analyze hedge funds generally display a number of majorweaknesses:
The models do not pay sufficient attention to the asymmetry of hedge fund returns (hedgefunds returns are not normally distributed). VaR type models therefore do not measure riskaccurately.
The models do not correct for the presence of widespread auto-correlation causingsignificant understatement of volatility of hedge fund returns.
Benchmarks used are not often significant resulting in spurious comparisons.
The models do not consider the impact of asymmetry on dependence measures such ascorrelation.
The models do not consider the persistence of any alpha.
The models generally seek to condense all of the relevant detail into one single
standardized comparative number that is frequently meaningless.
The weaknesses in existing models mean that the unique characteristics of hedge funds andrisks are not captured.

Attempts to address the non-linear dependence of hedge funds by coming upwith an analogue or modified correlation matrix using the additional co-skewness and co-kurtosis matrices. This allows for a better understanding ofthe underlying risk factors within the portfolio
