This study examines the potential impact of ESG performance on stock misvaluation, using a sample of Taiwanese listed companies with TEJ ESG scores, excluding the financial industry, from 2016 to 2023. Additionally, the study analyzes the moderating effects of information asymmetry and public ESG sentiment on the relationship between corporate ESG performance and stock misvaluation. Empirical results show that the company's ESG performance, as well as the performance of the three pillars E (environmental), S (social), and G (governance) in the previous year, significantly negatively affect stock misvaluation. In other words, companies with better ESG performance exhibit significantly higher pricing efficiency, especially for companies with overvalued stocks. However, the positive impact of ESG performance on pricing efficiency is significantly diminished when information asymmetry becomes more serious or public ESG sentiment becomes higher, indicating that both factors play an important moderating role.zh永續性錯誤定價定價效率市場情緒SustainabilityMisvaluationPricing EfficiencyMarket Sentimentmaster thesis
