[en] This paper examines the Fama-MacBeth test of asset pricing models through its application to the Fama and French model. The Fama and French 25 sorted portfolios, 30 industrial portfolios and their combination have been used. The data of monthly observations span over the period 1963-2008. Fama-MacBeth results reject the validity of the Fama and French model, but the presence of unexpected correlation casts doubt on these results.
