The Us

The study explores the relationship between the unemployment rate in the United States and South Africa’s stock prices from the beginning of 2013 to the last day 2017. The objective of this paper is to examine the impact of the US unemployment rate announcement on the South African financial market. Results of Impulse Response analysis show that there is a very minimal impact from the US unemployment announcement to South Africa’s stock prices which disappears within two days of the announcement. In addition, the Johannesburg stock exchange index marginally responds to own shocks, which marginally fades away within two days. These findings imply that the changes in the US employment policies have a direct ripple effect on the South African macroeconomic environment, its investing public sentiments and corporate confidence on the future prospects of businesses.

The objective of this study is to determine whether companies listed on the Johannesburg Stock Exchange overreacted to unexpected favourable and unfavourable company-specific news events during the period 1970 - 1984. The JSE appears to be inefficient in reacting to the announcement of unfavourable news; economically significant abnormal returns up to one year following the event are observed. The JSE does not appear to overreact to news of a favourable nature, there is only weak evidence of short-term overreaction. The selling pressure caused by panic selling could depress prices well below levels justified by the unfavourable news. The magnitude of the overreaction to unfavourable news is sufficient to enable astute investors to outperform the market by taking positions in these securities. Knowledge of the pattern of market overreaction can also be of value to investors for transactions that are to take place anyway.

Background: Integrated reporting has attracted much attention in the past few years, and South Africa has taken the lead in its development worldwide. An annual survey is published by Ernst & Young regarding the quality of the integrated reports of the top 100 entities listed on the Johannesburg Stock Exchange (JSE).Aim: The study on which this article is based was aimed at determining whether the assessment of an entity’s characteristics can predetermine the quality of the integrated report generated by that entity. Setting: This article focuses on an analysis of the integrated reporting of the top 100 entities listed on JSE for the financial years ending in 2013, 2014 and 2015.Methods: Comparison of categorical variables, mixed-model repeated measures ANOVA and generalised estimating equations were applied to identify the best classificators to distinguish between excellent integrated reporting and those reports where progress could still be made. Results: The results show that the type of industry the entity finds itself in, the size and profitability of the entity, as well as the composition of the members of the board, have an effect on the quality of the integrated report.Conclusion: Our results indicated that the type of industry, size of an entity, the profitability and composition of the board of directors, all have an effect on the quality of the integrated reporting. Our evidence will assist current and prospective stakeholders in evaluating the expected quality of an entity’s integrated report, through the evaluation of certain firm characteristics.

For any business to operate effectively, a governance framework that operates at the relevant maturity level is required. An organisational governance maturity framework is a tool that leadership can use to determine governance maturity. This study aims to determine whether the organisational governance maturity framework (developed by Wilkinson) can be applied to the selected retail industry organisation to assess the maturity of the organisation’s governance, limited to the ‘leadership’ attribute. Firstly, a high-level literature review on ethical leadership, ethical decision-making, ethical foundation and culture (‘tone at the top’), and organisational governance and maturity was conducted. Secondly, a Johannesburg Stock Exchange (JSE) listed South African-based company was selected for the empirical part of the study using a single case study research design. The empirical results confirmed that the organisational governance maturity framework can be used to determine the maturity level of organisational governance for the selected attribute of ‘leadership’.

Measure Of Dependence

The Johannesburg Stock Exchange as an efficient market. Finality has not yet been reached on the question whether the Johannesburg Stock Exchange complies with the requirements of the efficient market hypothesis. The results of the research that are published in this article is therefore an attempt to make a contribution to the debate regarding the Johannesburg Stock Exchange as an efficient market. By way of serial correlations as well as runs tests an investigation was carried out into the behaviour of the prices of 94 quoted shares for the period 1970 to 1977. The results of the study give rise to the conclusion that the Johannesburg Stock Exchange does not statistically comply with the weak form of the efficient market hypothesis (the random walk hypothesis), as a measure of dependence between successive price changes was found. Seen from an economic point of view it is, however, doubtful whether investors could use this small degree of dependence between price changes to gain higher returns on share investments.Uitsluitsel met betrekking tot die mate waartoe die Johannesburgse Effektebeurs aan die vereistes vir 'n rasionele mark voldoen, is nog nie verkry nie. Die resultate wat in hierdie artikel voorkom is daarom 'n poging om 'n bydrae in die debat rakende die Johannesburgse Effektebeurs as 'n rasionele mark, te maak. 'n Ondersoek na die markpryse van 94 genoteerde aandele vir die periode 1970-77 is deur middel van reekskorrelasiekoeffisiente en die lopietoets uitgevoer. Die resultate van die studie gee aanleiding tot die gevolgtrekking dat die Johannesburgse Effektebeurs nie statisties aan die swak vorm van die rasionele markhipotese (die willekeurige beweging van markpryse) voldoen nie, aangesien 'n mate van afhanklikheid tussen opeenvolgende prysveranderings gevind is. Uit 'n ekonomiese oogpunt gesien is dit egter twyfelagtig of beleggers hierdie afhanklikheid sal kan aanwend om hoer opbrengste op aandelebeleggings te bewerkstellig.

This study seeks evidence supporting the existence of market efficiency and exchange rate sensitivity on stock prices in the Johannesburg stock exchange (JSE). The sample includes the daily price indices of all securities listed on the JSE, and the exchange rate of the USD/Rand for the period since January 2000 to December 2004. The results from the unit root test, the ADF test and the causality test at the Granger sense provide evidence that the Johannesburg stock exchange (JSE) is informationally efficient. It has a long run comovement with exchange rate, and long run equilibrium or steady state. Hence, in JSE there is a strong possibility that foreign direct investors and forex market traders cannot influence and gain abnormal extra benefits by using exchange rate mechanism or by using exchange rate to forecast stock prices in the market. So, JSE is semi-strong form efficient. Through cointegration test, this paper gives more insight on the concept of market efficiency and the reliability of the results. These results are important to security analysts, investors, and security regulatory exchange bodies in policy making decision to improve the market conditions
