Abstract: Purpose - This study aims to comprehensively understand market reactions to Bursa Malaysia's announcement on mandatory climate-change-related disclosures, exploring sector-specific dynamics and cross-sectional influences. Design/methodology/approach - The study uses event study methodology on 412 listed firms to analyze market reactions around the announcement date. The sector-wise analysis further delves into variations across industries. Cross-sectional analysis explores the significance of environmental, social and governance (ESG) scores and firm controls in explaining the differences across sample firms. Findings - The event study reveals initial negative market reactions on the event day, with a subsequent shift from positive to negative cumulative impact, indicating the evolving nature of investor sentiment. The sector-wise analysis highlights heterogeneous effects, emphasizing the need for tailored strategies based on industry-specific characteristics. The cross-sectional findings underscore the growing importance of ESG factors, with firm size and performance influencing market reactions. Financial leverage and liquidity prove insufficient to explain cumulative abnormal return (CAR) differences, while past returns and volatility are influential technical factors. Practical implications - The economic significance of the results indicates a growing trend where investors prioritize companies with more substantial ESG scores, potentially driving shifts in corporate strategies toward sustainability. Better ESG performance signifies improved risk management and long-term resilience in the face of market dynamics. Regulatory bodies may respond by enhancing ESG reporting requirements, while financial institutions integrate ESG factors into their models, emphasizing the benefits of sustainability and financial performance. Originality/value - This research contributes to the existing literature by providing a nuanced analysis of market responses to climate-related disclosures, incorporating sector-specific dynamics and cross-sectional influences. The findings offer valuable insights for businesses and policymakers, emphasizing the need for tailored approaches to climate-related disclosure management.
