Risk management of financial crises: An optimal investment strategy with multivariate jump-diffusion models

Abstract

This paper provides an optimal asset allocation strategy to enhance risk management performance in the face of a financial crisis; this strategy entails constructing a good asset model- A multivariate jump-diffusion (MJD) model which includes idiosyncratic and systematic jumps simultaneously- A nd choosing suitable asset allocations and objective functions for fund management. This study also provides the dependence structure for the MJD model. The empirical implementation demonstrates that the proposed MJD model provides more detailed information about the financial crisis, allowing fund managers to determine an appropriate asset allocation strategy that enhances investment performance during the crisis.
