Abstract EN

This study aimed to measure the efficiency of the Jordan Stock Exchange at the semi-strong level in light of the accounting disclosure applied during 2018.

In order to reach such objective of the study, the methodology of the event study was used to identify the efficiency of the Jordan Stock Exchange, and to determine whether there is an impact on the disclosure of the financial statements on the stock prices on the day of the announcement of these statements, by calculating the average unusual return of shares of a sample of 80 listed companies.

In Jordan, the results of the event study showed that there is no statistically significant effect on the extraordinary returns of the stock exchanges under consideration on the day of the financial statements, which confirms the inefficiency of the Jordan Stock Exchange at the strong semi-level.
