Abstract

This paper examines how to improve tactical asset allocation by better risk management instead of concentrating on maximising returns. This is achieved by using forecasts of the time- varying conditional covariance matrix of returns obtained from a new specification of the multivariate GARCH process that is particularly well suited to modelling asset returns due to its generality, parameter parsimony and relative ease of estimation. We show that for a portfolio of four UK assets over the period 1976-1997 it would be possible to reduce portfolio risk by on average 5% compared with using the constant sample covariance matrix.
