ABSTRACT
This paper analyses returns and volatility on the Namibian and South African stock
markets. We use daily closing indices of the Namibian Stock Exchange (NSX) and
the Johannesburg Stock Exchange (JSE). The sample covers the period from January
4, 1999 to March 20, 2003. Our methodology has three main parts: (i) unit root
tests, (ii) cointegration analysis and (iii) volatility modelling. The results
show that both markets exhibit very low correlations, while there is no evidence
of linear relationship between the markets. Furthermore, volatility analysis shows
evidence of no spillover effects. Our results suggest that NSX is an attractive
risk diversification tool for regional portfolio diversification in Southern Africa.
