M.Comm. (Financial Management) / Since the late 1990s South African companies have started to dual list their shares in different countries, mainly to source capital from larger and more developed economies. In addition to this the level of participation by foreigners in the buying and selling of South African shares has increased. This leads to the question: should a local or a global CAPM (capital asset pricing model) be used to value shares that are traded in integrated global capital markets? This study focuses on dual-listed South African shares as these shares are most likely to be traded by investors globally. This study replicated aspects of earlier studies conducted in the Unites States of America and the United Kingdom, which are developed economies. By applying the same principles within a South African context, valuable insights might be derived relating to companies from developing economies. The main purpose of this study is to investigate the impact of using a global CAPM instead of a local CAPM to determine the cost of equity of South African companies. To this end, a sample of 26 dual-listed South African companies was selected using non-probability judgement sampling. Descriptive research was undertaken using quantitative analysis of secondary data. The cost of equity using the local and global CAPM was calculated for each of the selected dual-listed South African companies. The historical monthly returns of the dual-listed shares as well as each of the local and global risk factors during the period from 1 January 2005 to 31 December 2009 were used to calculate the local and global beta coefficients. The estimates of the local and global cost of equity were compared to ascertain whether there were significant differences for individual shares, as well as across different market sectors. While the results from similar previous studies on shares of developed countries by Koedijk and van Dijk (2004:474); Koedijk et al (2002:911); and Mishra and O‟Brien (2001:28) indicated insignificant differences between the local and global CAPM, this study indicated differences of 400 basis points and above for the sample of dual-listed South African companies. The findings in this study therefore suggest that the findings from studies conducted in developed economies cannot be generalised for companies in developing economies. In the South African market, shares across different sectors behave differently towards global risk factors; therefore this study highlighted the need for financial analysts to carefully consider using the global CAPM instead of the local CAPM when valuing shares that are traded in globally integrated capital markets. Using the incorrect cost of equity may result in incorrectly valuing a company as well as incorrect decision making.

Over the past two decades a number of Chinese companies have issued shares on both the Hong Kong Stock Exchange and on one of the Chinese stock exchanges. The Hong Kong-listed H-shares of Chinese dual-listed companies have traded at a persistent discount rate relative to the China-listed A-shares. As these shares represent the same ownership rights and cash flows, the shares should theoretically trade at the same price. The price differential between H-shares and A-shares should decrease as international markets continue to converge. The paper analyzes the persistence of the discount rates and the effects of both market and investor sentiment on the price disparity between the two shares. The paper also examines whether certain sectors consistently trade at larger discount rates relative to others.

M.Com. (Financial Management) / In 1995, the South African government needed to address the widening poverty gap. The manner in which they would do so was through the process of financial market liberalisation of the JSE. The intention behind the process of financial liberalisation on the JSE was to increase the liquidity of the JSE. The significance of this study is that it would provide regulators of financial markets, policy makers and academics information on the effectiveness of the liberalisation of the JSE on dual listed companies’ ability to grow in a sustainable manner. Previous literature has found the risk sharing benefit associated with financial market liberalisation. With the increased number of participants in market would increase the chance of successful trades. Previous studies have found that there is a positive correlation with financial market liberalisation and market liquidity. Exchange controls have been put in place to prevent capital flight in sudden economic down turns. Certain studies have found that financial market liberalisation on has had minimal impact on the market capitalisation This study investigates the effects the financial liberalisation on the JSE had on dual listed companies’ sustainable growth rates. A purposive sampling technique was used in this study and a sample of 28 dual listed companies was selected. The approach to this study was an explanatory approach and the research paradigm was archival. The statistical tools which were utilised in the study were broken into two components, namely, the descriptive statistics and the inferential statistics. The data that were used in the study were secondary data collected from I-Net Bridge. The results of this study indicated that the financial liberalisation of the JSE did have an impact on the sustainable growth rates of dual listed companies on the JSE. Recommendations were made in this study for the dual listed companies to improve their net profit margins. The methods in which the dual listed companies are able to improve their net profit margins are by finding competitive sustainable advantages. It was further recommended that the Income Tax Act No. 58 of 1962 needs to be amended to create a conducive economic environment for the dual listed companies to grow sustainably. It was further recommended that the dual listed companies on the JSE invest in human capital in order to improve their sustainable growth rate.
