The primary objective of this research is to measure the information asymmetry before, during, and after earnings announcements and how it relates to the drift in post-earnings announcements over an extended period. The study uses the bid-ask spread as an information asymmetry proxy and employs a market model to assess daily data on Indonesia’s equity market before, during, and after the earnings announcement. Data were analyzed using the t test and least squares regression. The study provides empirical evidence showing that the bid-ask spread increases significantly before the earnings announcement, indicating information uncertainties between sellers and buyers. The findings show that the market reacts to accounting information indicated by a significantly reduced bid-ask spread soon after the market digests the information, following the concept of semi-strong market efficiency. The study shows a cumulative abnormal return and bid-ask spread strongly correlated a few days following earnings. However, the analysis found no long-term association between bid-ask spread and post-earnings announcement drift. The study found that stock market sellers and buyers use accounting data to set prices and that earnings releases reduce the bid-ask difference. The study suggests that the market regulator supports timely disclosure of this information.

The substitution hypothesis postulates that various corpo- rate governance forms and dividend disbursements serve as alternatives. Given that transparent information disclosure mitigates agency issues by lessening information asymmetry and fortifying corporate governance, this study aims to explore the influence of Material Information Dis- closure which includes Groups A, B and Other Cases—characterized by their promptitude and significance—on dividends. Examining the period from 2018 to 2021 and encompassing a sample of 173 listed firms from the Tehran Stock Exchange, the findings affirm the substitution hypothesis. Moreover, Board independence is identified as a moderator in the rela- tionship between Material Information Disclosures and dividend. Fur- thermore, the findings indicate that during the Covid-19 period, Group A and Other Cases were more potent factors for dividend reduction than Group B disclosure.
