From the perspective of behavioral finance, this paper explores the impact of investor sentiment on asset mispricing and the moderating role of accounting conservatism in the relationship between investor sentiment and asset mispricing.The research shows that the more optimistic investors are, the more overvalued stock prices are. The improvement of accounting conservatism can alleviate the positive impact of investors' optimism on stock price overvaluation.The conclusion of this study provides a theoretical basis for relevant departments to mitigate the impact of investor sentiment on asset mispricing from the perspective of accounting conservatism, and also provides a way to improve the pricing efficiency of the securities market.
