This study examines 139 socially responsible and 4,898 conventional U.S. mutual funds from 2013–2020, analyzing social responsibility and irresponsibility by screening fund holdings. SR funds show higher weighted ESG ratings and subscores than conventional funds but underperform regarding corporate scandals, driven by social and governance issues, with no significant differences in environmental scandals. Passive SR funds tend to show higher weighted ESG scores than active SR funds. The findings offer valuable insights for ethical investors and fund managers to enhance investment strategies and decision-making.
