The COVID-19 pandemic and the subsequent lockdown brought about an exogenous and unparalleled stock market crash. The crisis thus provides a unique opportunity to test theories of environmental and social (ES) policies. This paper shows that stocks with higher ES ratings have significantly higher returns, lower return volatility, and higher operating profit margins during the first quarter of 2020. ES firms with higher advertising expenditures experience higher stock returns, and stocks held by more ES-oriented investors experience less return volatility during the crash. This paper highlights the importance of customer and investor loyalty to the resiliency of ES stocks.
新冠疫情及随后的封锁引发了一场前所未有的外部股市崩盘。因此,这场危机为检验环境与社会(ES)政策理论提供了一个独特的机会。本文表明,在2020年第一季度,环境、社会评分较高的股票具有显著更高的回报率、更低的回报波动率和更高的营业利润率。广告支出较高的环境、社会企业股票回报率更高,在股市崩盘中,由更多注重环境、社会的投资者持有的股票回报波动率更低。本文强调了客户和投资者忠诚度对环境、社会股票弹性的重要性。
