The paper tries to find evidence supporting the impact of continuous policy reforms on the market efficiency on the Dhaka Stock Exchange (DSE). Different policies formed/reformed from 1994 to 2005 were categorized in eleven groups depending on their time of issue and subject matter. To get the result, both nonparametric test (Kolmogrov-Smirnov normality test and run test) and parametric test (autocorrelation test, autoregression) have been performed. Analyses were done for each policy group, and it is found that formed/reformed policies for DSE during the study period failed to improve the market efficiency even in the weak form level.

Different policies formed/reformed from 1994 to 2005 were categorized in eleven groups depending on their time of issue and subject matter. To get the result, both non-parametric test (Kolmogrov-Smirnov normality test and Run test) and parametric test (Auto-correlation test, Auto-regression) has been performed. Analyses were done for each policy group, and it is found that formed/reformed policies for DSE during the study period failed to improve the market efficiency even in the weak form level

<p>We study the random walk behavior of Chittagong Stock Exchange (CSE) by using daily returns of three indices for the period of 2006 to 2016 employing both non-parametric test (run test) and parametric tests [autocorrelation coefficient test, Ljung– Box (LB) statistics]. The skewness and kurtosis properties of daily return series are non-normal, with a hint of positively skewed and leptokurtic distribution. The results of run test; autocorrelation and Ljung–Box (LB) statistics provide evidences against random walk behavior in the Chittagong Stock Exchange. Overall our result suggest that Chittagong Stock Exchange does not exhibit weak form of efficiency. Hence, there is opportunity of generating a superior return by the active investors.</p>

Since 1988, Indonesian capital market, especially Jakarta Stock Exchange has been grown fast. Then, come up questions about capital market efficiency. The capital market is efficient if the securities prices reflecting all available informations and the prices are fair. Thus, investor could not achieve abnormal return. So, with this reasons and facts, the research analyze weak form Indonesia capital market efficiency at Jakarta Stock Exchange in periode January-July 2001. This research used samples 25 emitent. Autocorrelation test, run test, and variance ratio test were used to test the capital market efficiency. The result is that Indonesian capital market is efficient in weak form with 1% significance level. It means that securities movement have random walk pattern. Thus, investors could not achieve abnormal return if just used technical analysis with past securities prices data to predict prices in the future.

This study aims to determine the extent to which the Boards of Directors of the industrial Jordanian Companies listed on Amman Stock Exchange (ASE) comply with the controls of composing audit committees, their working mechanisms, and the impact on the corporate governance. To achieve the objectives of this study, (155) questionnaires were developed and distributed to the staff members relevant to the subject matter of the study. Out of distributed questionnaire, (144) responded questionnaires only were collected from respondents. The number of questionnaires analyzed was (135) and a T-test has been used to test the hypotheses. The results of the study showed that there is a statistically significant correlation on the existence of the commitment of the Boards of Directors of the Jordanian Listed Companies to the disciplines of audit committees&rsquo; formation and their mechanisms of work. The results also demonstrated the existence of impact of this commitment on the governance of these companies. The commitments to these controls and their work mechanisms have been developed to enhance corporate governance in Jordanian companies.

Objectives: Europe is one of the important markets for traditional tobacco. We analyzed the impact of exchange consolidation on securities market efficiency, so as to enable tobacco enterprises to improve the financing efficiency of the stock market and carry out transformation and upgrading. Methods: In this work. We’re based on efficient market theory, the merger of Pan-European Stock Exchange and Oslo Stock Exchange, Norway in June 2019 is analyzed through empirical analysis. The logarithmic returns of 25 listed companies in the Oslo Stock Exchange OBX-25 index were analyzed using OLSN Chow and KPSS tests. Results: It is found that of 72% of securities, the explanatory power of market returns for securities returns is increased, which shows significant improvement in market efficiency. The merger of stock exchanges can indeed improve the market efficiency. In addition, through the KPSS test, it is found that the merger of stock exchanges can improve the market efficiency. As time goes by, however, the validity decreases. Conclusion: The improvement of the efficiency of the securities market will be conducive to the financing efficiency of listed tobacco companies in the secondary market, promote the transformation of enterprises, and contribute to the tobacco control and the health of the population in Europe.

Background: There are various studies that confirm the efficiency of the Johannesburg Stock Exchange (JSE), implying that there are no opportunities for active portfolio managers to earn excess returns over the long run.Aim: The aim of the research is to prove that the sub-indices on the JSE go through cycles of efficiency and inefficiency even though the JSE as a whole might be considered informationally efficient.Setting: Although the JSE as a whole can be considered to be weak-form efficient, portfolio managers are not bound to investing in large liquid stocks alone. Many aggressive funds allow managers to also allocate a portion of their portfolio to smaller stocks. This has implications when considering the efficiency of the stocks being selected.Methods: Given the impact efficiency has on portfolio selection, we test for the adaptive market hypothesis using a representative sample of stock indices by means of the automatic variance ratio test, the Chow–Denning joint variance ratio and the joint sign test on the JSE.Results: Our results confirm that some of the smaller, and in some instances younger, indices are not always as efficient as the all share index, thus allowing portfolio managers with an active management approach some opportunities to profit from informational inefficiencies in the market.Conclusion: The practice of active management by portfolio managers in the South African market seems to defy logic if one considers the fact that the JSE as a whole is at the very least weak-form efficient. By proving that some of the sub-indices that make up the all share index are inefficient most of the time, this article shows that the phenomenon of active portfolio managers is less of a surprise.

Purpose This study aims to provide one of the first empirical investigations of market efficiency for developed markets during the recent global financial crisis. Design/methodology/approach Using the Morgan Stanley Capital International (MSCI) country indices as proxies for national stock markets, the study conducts a battery of econometric tests in assessing weak-form market efficiency for the developed markets. Findings The inferential outcomes are consistent among the different tests. Specifically, the study finds that the majority of developed markets are weak-form efficient while the USA is the sole equity market to be commonly diagnosed as weak-form inefficient across the different tests when using full period data spanning the January 2008-November 2011 period. However, when basing the analysis on one-year subsamples over the identical time period, this study fails to reject weak-form market efficiency for all of the developed markets and presents evidence consistent with the Adaptive Market Hypothesis as described by Urquhart and Hudson (2013). When applying technical analysis for the case of the USA over the full study period, the results indicate that the return predictabilities can be exploited for some horizon of variable length moving average (VMA) trading rules. Originality/value This study provides one of the first empirical investigations of market efficiency for developed markets during the recent global financial crisis using an extended set of econometric tests. The study contributes to the existing body of empirical research that formally assesses the impact of a financial crisis on stock market efficiency and underlines the significance and relevance of examining market efficiency through subsample analysis.
