Mr Xu’s research focused on how to estimate the portfolio value-at-risk and how to evaluate the multivariate density forecast. These issues are related to the portfolio selection and the multivariate option pricing. Traditional portfolio theory often does not support empirical evidence that the portfolio returns are asymmetrically distributed. Consequently, it has been found to be questionable in explaining the financial market. In view of this, Mr Xu used a new and highly sophisticated statistical instrument, called the Archimedean copula, to model the asymmetrically distributed portfolio returns. The research results are beneficial to financial risk management as they demonstrate that the Archimedean-copula-based portfolio model is an efficient tool for the purpose of international risk diversification.
