This research paper investigates the impact of the Hindenburg Research report published in January 2023 on the stock prices and financial performance of the Adani Group of companies. An event study methodology is employed to analyze the effect of the Hindenburg report on Adani Group stocks. Additionally, a panel data regression model is used to assess financial performance. The model included abnormal returns as the dependent variable and Size, Leverage, Liquidity, Profitability, and Tangibility as independent variables. The analysis reveals significant negative abnormal returns for Adani Group stocks following the report’s release, indicating a substantial decline in stock prices. This suggests that the market reacted strongly to the allegations of fraud and manipulation. The financial performance analysis further highlights a marked adverse impact on the companies’ quarterly results post-report. This research addresses a critical gap in existing literature by focusing not only on the immediate aftermath but also on the sustained effects of the Hindenburg report on Adani Group’s stock performance and financial health. Investors, regulators, and policymakers can gain valuable insights from this study on the importance of monitoring and responding to corporate allegations. It emphasizes the necessity for due diligence and the potential market repercussions of financial misconduct.
