Financial Performance and Investment Outcomes of Socially Responsible Firms

Abstract

This study explores whether firms recognized for strong ethical practices also demonstrate stronger financial results and superior risk-adjusted returns. Companies named to Ethisphere’s 2024 World’s Most Ethical Companies list are used as an indicator of ethical commitment. From this group, portfolios of publicly traded U.S. and non-U.S. firms are formed and analyzed from January 2015 to December 2024. Firm performance is evaluated using key accounting measures, including profit margin, return on assets, return on equity, asset turnover, and leverage ratios. Investment performance is examined using stock returns, beta, standard deviation, and commonly used risk-adjusted performance metrics. The U.S. ethical portfolio is benchmarked against the S&P 500 Index, whereas the non-U.S. ethical portfolio is compared to the MSCI World Index. The findings show mixed but significant differences. When adjusting strictly for market risk, the U.S. ethical portfolio trails the S&P 500, yet it produces stronger returns relative to total volatility, indicating more consistent performance with lower overall variability. In contrast, the non-US ethical portfolio exceeds the MSCI World Index on both market-risk and total-risk-adjusted bases. These firms also display stronger profitability, more conservative leverage levels, and reduced volatility in earnings. Taken together, the results question the assumption that ethical corporate conduct comes at the expense of financial success. Instead, the evidence indicates that incorporating ethically recognized firms—particularly outside the United States—may contribute to improved diversification, enhanced risk control, and stronger long-term portfolio performance.
