This paper studies the issue of socially responsible investing (SRI), showing that there is a correlation between growth companies, innovation and sustainability. It begins with a definition of SRI and then examines the history of SRI. Establishing that the concept of SRI has been in existence for hundreds of years, it then presents the four principal areas of current SRI activities namely: social research, shareholder advocacy, social venture capital, and community investing. In addition, it also looks at the four SRI strategies: screening, divesting, shareholder activism, and positive investing. The paper also examines the crucial question of whether SRI makes good business sense. Our methodology for finding out whether SRI makes business sense involves comparing the performance of socially responsible funds, with that of vice funds. The paper concludes with an analysis of the results of the findings, as well as suggestions for further research.
