Integration of the GCC Stock Markets

Abstract

This study analyzes the short- and long-term interdependence among the Gulf Cooperation Council (GCC) stock markets, namely, Kuwait, Saudi Arabia, Bahrain, Emirates, and Oman. The study finds a solid long-term relationship among the GCC stock markets and that each market contributes significantly to that relationship. The short-term relationship is also supported through the causality tests as well as through impulse response functions. The analysis reveals the Kuwait stock market to be the most influential during the examined period. Also, a feedback exists between the Saudi and the Emirates stock markets. In order to corroborate the results, an ARDL model is specified and its results confirm the cointegration tests. Overall, the results place doubts against the investment diversification principle.
