Performance vs Persistence : Assess the alpha to identify outperformers

TL;DR

This paper evaluates the effectiveness of additional factors in analyzing alpha persistence and assesses manager quality based on investment choices within the context of performance attribution models.

Contribution

It extends Fama and French's 3-factor model by incorporating two additional factors to better analyze alpha persistence and manager quality.

Findings

Additional factors improve alpha persistence analysis.

Manager investment choices correlate with alpha generation.

Enhanced model offers better performance attribution insights.

Abstract

The number of pension funds has multiplied exponentially over the last decade. Active portfolio management requires a precise analysis of the performance drivers. Several risk and performance attribution metrics have been developed since the 70s to guide investors in their investment choices. Based on the study made by Fama and French (2010) we reproduce the experiment they had carried out in order to complete their work using additionnal features. Throughout this study we draw a parallel between the results obtained by Fama and French (2010) with the 3-factor model. The aim of this paper is to assess the usefulness of two additional factors in the analysis of the persistence of alphas. We also look at the quality of the manager through his investment choices in order to generate alpha considering the environment in which he operates.
