Effect of Corporate Social Responsibility on Portfolio Performance: Evidence From Turkey

Metin Borak and Hatice Dogukanli

SAGE Open, 2023, vol. 13, issue 4, 21582440231216192

Abstract: This study investigates the performance of corporate social responsibility (CSR) portfolios based on ESG scores of stocks traded in Borsa Istanbul (BIST). It also evaluates the performance of a trading strategy that represents buying portfolios that include companies with high CSR performance and selling portfolios comprising companies with low CSR performance. Therefore, two portfolios with high and low CSR performance were formed from stocks traded in Borsa Istanbul. These portfolios’ performances were compared from July 2010 to June 2020. The findings show that the alpha coefficient of the portfolio containing stocks of companies with high CSR performance is generally positive and significant. Thus, companies’ past CSR performances provide valuable information for investors. Additionally, based on this, investors can achieve a superior performance against the market. However, the alpha of the difference portfolio, which shows the difference between the two portfolios’ performance, is, in most cases, insignificant. This suggests that there is no proof that the portfolio comprising companies with high CSR performance is superior to the portfolio including companies with low CSR performance. These findings are supported by additional testing. Consequently, our result provides supporting evidence for the “no effect†hypothesis.
