An approach recently developed by Fama and French (2000) is applied to the study of whether UK company proﬁtability is mean-reverting. A sample of roughly 987 ﬁrms per year for a period from 1982–2000 is used, drawn from Datastream. In a simple partial adjustment model convergence towards the mean at a rate of about 25% per year is found. The results are very similar in direction to those of Fama and French (2000) but the results do not display signiﬁcant non-linearities. The change in proﬁtability appears to be more strongly inﬂuenced by dividends in the UK.
