Socially responsible investing has presented itself as a growing, multifaceted, advanced and sophisticated investment philosophy. Socially responsible investment (SRI) involves incorporating social, ethical and responsible investment objectives with financial investment objectives during the investment decision-making process. Social, ethical and responsible investment objectives are set in line with environmental, social and corporate governance (ESG) criteria which are established within the SRI strategy followed. SRI strategies include screening (negative, positive and best-of-sector), shareholder activism and cause-based investing. Although international SRI markets such as that of the United States of America and the United Kingdom are sophisticated and established markets, the South African SRI market is still relatively new and is yet to reach its full potential. Thus, as a growing market, little research regarding the long term risk-adjusted performance of SRI funds in South Africa has been conducted. The long term risk-adjusted performance of the sample of SRI funds was measured through the use of five risk-adjusted performance measures, namely the Treynor ratio, Sharpe ratio, Jensen’s alpha, Sortino ratio and Omega ratio, and through the use of three performance measurement models which included the capital asset pricing model (CAPM), Fama-French three-factor model and Carhart four-factor model. The risk-adjusted performance of the sample of SRI funds was measured with the intent to establish if these funds out- or underperformed against three benchmark categories, namely the Financial Times Stock Exchange/Johannesburg Stock Exchange (FTSE/JSE) SRI Index, a matched sample of conventional investment (non-SRI) funds and the FTSE/JSE All Share Index. The probable effect of the 2007/08 global financial crisis was also measured to analyse whether such a hazardous market event affected the performance of the SRI funds. According to the results and findings, the risk-adjusted performance of the SRI funds has improved over the research period. However, the SRI funds neither outperformed nor underperformed against the three benchmark categories over the research period. The performance measurement models’ analysis indicated that the SRI funds were less sensitive to market fluctuations, more exposed to small capitalisation portfolios, more growth-oriented, and exhibited significant momentum after the period of the 2007/08 global financial crisis. Furthermore, the analysis indicated that the SRI funds significantly underperformed against the non-SRI funds during the Performance of socially responsible investment funds in South Africa research period. Mixed results were obtained with regards to the probable effect of the 2007/08 global financial crisis on the performance of the SRI funds.

Capital Asset Pricing Model (CAPM) is an equilibrium model to test relationship between expected return and market risk (Sharpe, 1964). The model research on pricing and return when the securities market reaches equilibrium and investors are rational and investing by diversification based on Markovitz portfolio theory (Markovitz, 1952). Fama and MacBeth (1973) proposed a cross-sectional testing methodology on CAPM and this regression method has been widely used in testing CAPM in developed markets since then. While CAPM is hard to explain more and more market anomalies (excessive return in smaller market value company) in cross section regression, Fama and French (1992) added two more factors (SMB and HML) and proposed three factor model. The empirical results show that three factor model is superior to CAPM in developed markets. Relevant studies have been conducted by Manjuunatha (2006) and Trimech et al. (2015) but show different results. This dissertation will use Fama-MacBeth cross section approach to test CAPM and Fama-French's three factor model in Chinese and Polish stock market respectively. Following Fama and MacBeth (1972) and Shweta and Anil (2015), three sub periods of Polish and Chinese stock market returns ranging from 2007 to 2018 are examined. The empirical results in this thesis...

Subject background and discussion: In recent decades, issues of human rights, labor and environmental change has been hot topics world wide, which also has influenced the financial market. More and more investors use socially responsible investing (SRI) screens when constructing their portfolios. One form of SRI screen is to choose companies that have satisfied employees. Existing theory says that employee satisfaction is an intangible asset to the firm that will positively affect a firm’s performance in the future. Intangible assets are often unrecognized by the market and thereby not incorporated in the stock price. The efficient market hypothesis has been studied and debated for several decades. Proponents of the EMH argue that all available information is incorporated in the stock price, thus it is not possible to systematically beat the market. However, EMH is controversial, since research has shown different results regarding the possibility to make abnormal return from various investing strategy. Research question: Is it possible to make abnormal returns by investing in a portfolio of worldwide firms with top scores on the SRI screen employee satisfaction? Purpose: The main purpose of this study is to examine investor’s possibility to make abnormal return with controls for multiple risk factors by investing in worldwide firms with top scores in employee satisfaction. One sub-purpose is to examine how the market values intangibles depending on the degree of market efficiency. Another sub-purpose of the study is to test two different portfolio weighting methodologies, equally- and value weighted, and observe the differences between them. Theory: This study deals with the efficient market hypothesis and the concepts of SRI, employee satisfaction, intangible assets and several risk-adjusted measurements. Method: We have chosen to perform a quantitative study with a deductive approach to answer our research question. We used a sample size of 696 firms based on “Great Place to Works”- lists of companies with high employee satisfaction to construct sex portfolios with different holding periods and strategies. These portfolios have been explored and tested significantly with both equally and value weighted methods. Result/Analysis: The study finds significant evidence of an average annual abnormal return of 3,66% and 2,43% for our main portfolio over the market for equally- and value weighted, respectively, using the three-factor model. When adjusting for momentum, thus employing the four-factor model, all the predictive variables still identify strong persistence in the abnormal return, with statistical significance. Conclusion: The results show that it is possible to make abnormal returns, during the observed time period, regardless of the weighing methodology, although the equally weighted received higher abnormal returns. Thus, the market efficiency appears to be in weak form and does not fully value intangibles.
