This research analyzes the effect of ESG disclosure scores on stock price synchronicity among Australian mining companies, exploring each pillar’s contribution. The final sample consists of 275 firm-year observations of Australian listed mining companies covering the period from 2020 to 2024. Data was collected from Bloomberg and Factset. This study adopts the price synchronicity model proposed by Hutagaol-Martowidjojo et al. (2023) and panel data regression is employed to analyse and test the research hypotheses. The study concludes that ESG disclosure is significantly associated with higher price synchronicity, implying that while ESG disclosure scores enhance overall market visibility, they may simultaneously reduce the uniqueness of firm-specific information.

摘要

This research analyzes the effect of ESG disclosure scores on stock price synchronicity among Australian mining companies, exploring each pillar’s contribution. The final sample consists of 275 firm-year observations of Australian listed mining companies covering the period from 2020 to 2024. Data was collected from Bloomberg and Factset. This study adopts the price synchronicity model proposed by Hutagaol-Martowidjojo et al. (2023) and panel data regression is employed to analyse and test the research hypotheses. The study concludes that ESG disclosure is significantly associated with higher price synchronicity, implying that while ESG disclosure scores enhance overall market visibility, they may simultaneously reduce the uniqueness of firm-specific information.
