This paper demonstrates that the use of GARCH-type models for the calculation of minimum capital risk requirements (MCRRs) may lead to the production of inaccurate and therefore inefficient capital requirements. We show that this inaccuracy stems from the fact that GARCH models typically...

This paper investigates the frequency of extreme events for three LIFFE futures contracts for the calculation of minimum capital risk requirements (MCRRs). We propose a semi-parametric approach where the tails are modelled by the Generalized Pareto Distribution and smaller risks are captured by...

This paper compares a number of different extreme value models for determining the value at risk of three LIFFE futures contracts. A semi-nonparametric approach is also proposed where the tail events are modeled using the Generalised Pareto Distribution and normal market conditions are captured...

Factor models are frequently applied to hedge fund returns in an attempt to separate the return from identified risk factors (beta) and from manager skill (alpha). More recently, these same techniques have been used to replicate the returns from hedge fund strategies with varying degrees of...
