The impact of ESG investment on fund performance: Evidence from mutual fund style drift
This study analyzes the impact of ESG investment on fund performance using a sample of China's open-end mutual funds from January 2006 to December 2020. ESG investment style scores were constructed based on portfolio weights and MSCI ESG investment styles. The results show a significant positive correlation between overall ESG investment styles (including the environmental, social, and governance sub-dimensions) and fund performance. After adjusting for four-factor risk, the High-Low strategy (Long-short) yielded monthly excess returns ranging from 0.371% to 0.465%. After considering different degrees of style drift, the funds with lower style drift experienced a stronger positive impact from ESG investment styles, with the High-Low strategy contributing up to 0.615% in monthly excess returns. These findings offer practical strategies for fund managers to optimize portfolio allocation and provide valuable guidance for investors selecting ESG-style funds. This study provides theoretical and empirical support for sustainable finance development in emerging markets.
