Abstract
This study investigates the weak form market efficiency of indices for the Financial returns as listed in the Muscat Securities Market (MSM30 index) in Oman, by conducting monthly observations from January 2010 until December 2014. All macroeconomic variables, covered under Financial Sectoral Index , were found to be co-integrated. Furthermore, the findings exhibit that oil prices as a determinant have the most significant relationship on the Financial Stock Index. It was found that the CPI to exert no influence on the Financial index prices. Whilst inflation appears to be a third determinant, there is a significant effect on the Financial and Service indices prices. The overall findings from the period suggest that the Financial Index Prices listed in MSM30 is inefficient in weak form market efficiency, which is consistent with previous studies examining the weak form of market efficiency.
