The impact of the adoption of IFRS standards on the informational relevance of financial performance indicators of companies listed in the Casablanca BVC[L’impact de l’adoption des normes IFRS sur la pertinence informationnelle des indicateurs de performance financière des sociétés cotées à la BVC de Casablanca]

The adoption of international financial standards should provide companies with enormous benefits, especially through the production of reliable and high-quality financial information by strengthening the explanatory power of accounting and stock market performance indicators. These indicators are key elements used to assess the value created by firms. This article is proving to be a great contribution to scientific research in this field. It will allow an empirical approach to assess the impact of the adoption of IFRS standards on the informational relevance of financial performance indicators. In figures, 93 observations were collected from companies listed on the Casablanca stock exchange from 2015 through 2020. We used a theoretical framework based essentially on the theory of financial market efficiency and a series of empirical tests on the two samples: IFRS- Sample Standards and Local- Sample Standards. Ultimately, our main results seem to indicate that the implementation of IFRS standards contributes to slightly to the improvement of the informational relevance of accounting figures for Moroccan companies listed in the Casablanca stock market.
