A characteristic of hedge funds is not only an active portfolio management, but also the allocation of portfolio performance between different accounts, which are the accounts for the external investors, an account for the management firm and a provision account. Despite a lack of transparency...

High frequency transaction prices exhibit two major cha racteristics: they are discrete in level and only exist at random transaction dates. In this paper, we seek to model transaction price dynamics, taking into account these two features. We specify the transaction price process as a Markov...

This paper reviews the fund ratings based on Sharpe performance measures. We define a battery of performance measures in a mean-variance framework. They differ by the information taken into account in their computation, but also by the potential use of the fund by the investor. We apply these...

This paper analyses how an external adverse shock will impact the financial situations of banks and insurance companies and how it will diffuse among these companies. In particular we explain how to disentangle the direct and indirect (contagion) effects of such a shock, how to exhibit the...

The standard mean-variance approach can imply extreme weights in some assets in the optimal allocation and a lack of stability of this allocation over time. To improve the robustness of the portfolio allocation, but also to better control for the portfolio turnover and the sensitivity of the...

We develop a new methodology to analyse the dynamics of liquidation risk dependence in the hedge funds industry. This dependence results either from a common exogenous factor, or from conta- gion phenomena caused by an endogenous behaviour of fund managers. Our empirical analysis shows that the...

This paper presents a simple and efficient exogenous outlier detection & estimation algorithm introduced in a regularized version of the Kalman Filter (KF). Exogenous outliers that may occur in the observations are considered as an additional stochastic impulse process in the KF observation...

This paper introduces a new fund performance measure, called the L-performance. It is proposed as an alternative to the Sharpe performance measure that is commonly used for fund performance valuation despite its inability to account for skewness and thick tails of fund return distributions. The...
