This paper aims at examining the impact of oil price on GCC countries’ stock market returns. We apply wavelet analysis model for examining the relationship between oil and stock market returns. Using monthly data from May 2005 to December 2011, our results suggest that not all stock market in GCC region have a positive relationship with oil price as some have, instead, negative relationship with oil price. Oil price has a negative relationship with Bahrain, Saudi Arabia and United Arab Emirates. However, in consistent with literature review, oil price has a positive relationship with Kuwait, Qatar as well as Oman. | The dynamic co-movements between oil and stock market returns in: The case of GCC countries
