    Dynamic density forecasts for multivariate asset returns


    Stoja, E & Polanski, A, 2011, ‘Dynamic density forecasts for multivariate asset returns’. Journal of Forecasting, vol 30., pp. 523 - 540


    We propose a simple and flexible framework for forecasting the joint density of asset returns. The multinormal distribution is augmented with a polynomial in (time-varying) non-central co-moments of assets. We estimate the coefficients of the polynomial via the method of moments for a carefully selected set of co-moments. In an extensive empirical study, we compare the proposed model with a range of other models widely used in the literature. Employing a recently proposed as well as standard techniques to evaluate multivariate forecasts, we conclude that the augmented joint density provides highly accurate forecasts of the ‘negative tail’ of the joint distribution.
