Abstract

The paper analyzes the time variation in volatility in Doha Securities Market and examines the presence of structural changes in GARCH-based conditional volatility during the period 2002-2008. This issue is related to the market liberalization reforms permitting foreign investors to enter the equity market in 2005.The analysis reveals that there is a high risk in return equation. It also indicates that the return is positively and more significantly related to the risk. The GARCH-Mean model shows that the volume term has a more significant parameter in both return and risk equations, and that the information flow provided to the market comes from the risk and return variables. There is a high persistence of the shocks in the volatility, but it was less in the first sub-period compared to its persistence after the entry of foreign investors.
