Abstract:This paper contrasts the performance of three time series models, a simple stochastic drift, GARCH (generalized autoregressive conditional heteroskedasticity), and a time varying parameter CAPM (capital asset pricing model) for three of SADC's smallest equity markets: Namibia, Swaziland and Mozambique. Analysis of the portfolio characteristics for each reveals the level of integration with South Africa using optimized portfolio frontiers. In addition, the implications of adopting a minimum investment retention levy by the smaller States is examined. Namibia is found to exhibit the greatest degree of integration with South Africa, followed to a much lesser extent by Swaziland and Mozambique. The evidence suggests that investors in the smaller markets would face considerable additional costs should such a policy be adopted. Bibliogr., notes, ref., sum. [Journal abstract]
