The market efficiency hypothesis has become an important concept for all investors looking to own internationally diversified portfolios, which coincides with an increase in investment flows between all countries, both developed and undeveloped. This study was aimed at investigating the efficiency of a group of Arab stock markets located in the Middle East and North Africa (MENA) region according to the Random Walk Hypotheses (RWH) at weak form. The study covered the markets of Jordan, Egypt, Saudi Arabia, UAE, Bahrain, and Oman.
The empirical results of all tests used in this study rejected the RWH at a weak form for all markets through all tests applied – Unit root test, Variance Ratio Test, and Run Test.
The result of this study contradicts the results of many studies conducted on developed and emerging markets. This can be a good indication of the ineffectiveness of the reforms that have been adopted by responsible bodies on these markets.
Based on this result, all efforts made to expand and deepen these markets should be intensified by improving liquidity, transparency, enhancing investment culture in these countries; supporting legislative and regulatory reforms to attract investment, and developing the financial sector in these markets as a whole.

The present study aims at testing the weak form of market efficiency of the individual stocks listed on the Bahrain Bourse for the period 2011 to 2015. Weak form of EMH is tested using the Kolmogorov-Smirnov goodness of fit test, run test and autocorrelation test. The K-S test result concludes that in general the stock price movement does not follow random walk. The results of the runs test reveals that share prices of seven companies do not follow random walk. Autocorrelation tests reveal that share prices exhibit low to moderate correlation varying from negative to positive values. As the study shows mixed results, it is difficult to conclude the weak form of efficiency of Bahrain Bourse.

Investment Management and Financial Innovations Volume 16, 2019 Issue #2 pp. 101-115 Views: 2019 Downloads: 300 TO CITE АНОТАЦІЯThis research explores the influence of foreign ownership on non-financial public shareholding firms in the Amman Stock Exchange (ASE). The study involved an investigation into the connection between non-Jordanian ownership and the company growth opportunity, stock liquidity, leverage, dividend policy and business output. The results highlight that foreign ownership can provide improved corporate governance practices by playing a decisive role in increasing the growth opportunity and enhancing the firms’ market valuation, as measured by Tobin’s Q. Moreover, the findings indicate that companies with foreign board membership have better operating performance and higher firm value. The rewards were reaped by foreign investors based on their superior monitoring ability, which affects the decisions made and actions taken by management.

Investment Management and Financial Innovations Volume 15, 2018 Issue #1 pp. 311-327 Views: 1939 Downloads: 223 TO CITE АНОТАЦІЯExtant literature shows the positive impact of institutional development on investor rationality and market efficiency. The authors extend this evidence by investigating the performance-flow relationship in the Chinese mutual fund market before and after the enforcement of the revised Law of the People’s Republic of China on Securities Investment Fund. Empirical evidence reveals that Chinese investors irrationally chase past star performers before institutional reform, but gradually become rational and less obsessed with star-chasing behaviors after reform. Moving one percentile upward in the relative performance among the star funds is associated with money inflows by 0.532% after reform, much lower than 1.433% before reform. The findings confirm the positive influence of institutional development on investor rationality and market efficiency. The successful experience can be borrowed by other emerging markets with less developed institutions.
