This study empirically tests and compares the performances of three famous financial asset valuation models in the Moroccan stock exchange: CAPM, the Fama and French three-factor model, and the Fama and French five-factor model. Our sample considers monthly data covering the sample period of July 2002 to June 2020. The main findings reveal that the GRS test typically rejects each of the examined model. On the basis of our analysis, we find that the value effect is more pronounced than the size effect. However, profitability and investment effects are almost absent. Regarding the factor spanning tests, the results show that the value factor was not redundant. Beyond this, the size and investment factors are the redundant factors. In Morocco, the market factor is the most powerful factor, perhaps assisted by value and profitability factors. Although the CAPM performs poorly in capturing the variation in Moroccan returns, the market factor continues to play an important role, even after adding other factors. Overall, all the tested models were improved slightly, but leave part of the variation in Moroccan stock returns unexplained.

Fundamental anomalies are explored, for the first time, in the Moroccan stock market. The sample includes non-financial companies from July 2001 to June 2020. We carry out, initially, sorts of returns on anomaly indicators, then, we follow through a regression analysis using a fixed-effect model and the system generalized method of moments methodology. The findings emphasize a significantly positive relationship between returns and the book-to-market ratio and a significantly negative relationship between returns and each of the price-to-earnings and the price-to-cash flow ratios. Regarding the size and the leverage effects, the findings highlight their absence. Finally, we cannot ascertain the existence of a positive or negative price-to-sales effect considering the contradictory results of the tests.

Résumé : Objet : Dans cet article, nous testons et comparons le pouvoir explicatif des deux modèles d’évaluation des actifs financiers : le MEDAF et le modèle à trois facteurs de Fama et French (1993). Méthodologie : En respectant la méthodologie de Fama et French (1993), notre étude s’étale sur la période de juillet 2012 à juin 2020. Résultats : Les principaux résultats soutiennent la supériorité du modèle à trois facteurs. Les facteurs taille et book-to-market jouent un rôle important dans l'explication des rendements des titres marocains. En outre, les résultats affirment la présence d'un effet book-to-market faible mais d'un effet taille significatif. Malgré la prééminence du modèle de Fama et French dans la description de la série chronologique des rendements des actions, le modèle laisse une part inexpliquée de la variation des rendements des titres marocains. Originalité : notre étude est la première à confronter les deux modèles populaires dans la littérature financière dans le marché Marocain qui est un marché émergent. Ainsi, notre étude vient corroborer d’autres études conduites dans des marchés émergents et confirme l’hypothèse selon laquelle les spécificités de ces marchés impactent significativement le pourvoir explicative des modèles d’évaluation des actifs financiers.
