Bayesian Performance Evaluation

Abstract: This paper proposes a Bayesian method of performance evaluation for investment managers. We begin with a flexible set of prior beliefs that can be elicited without any reference to probability distributions or their parameters. We then combine these prior beliefs with a general multi-factor model and derive an analytical solution for the posterior expectation of "alpha", the intercept term from the model. This solution can be computed using only a few extra steps beyond maximum likelihood estimation and does n… Show more

“…In some applications, one may wish to relax the constraint in equation (10) and allow certain types of managers to have a positive expectation of α . This case is solved in a previous version of the paper (Baks, Metrick, and Wachter (1999)). …”

“…Por exemplo, Baks et al (1999) utilizam uma abordagem bayesiana, definindo priors para os alfas de acordo com a habilidade do gestor na seleção de ativos. Chevalier e Ellison (1999), por sua vez, utilizam características pessoais dos gestores dos fundos para explicar diferenciais de performance (como resultado, encontram que gestores mais jovens, e provenientes de faculdades com maiores SAT's, obtêm resultados significantemente superiores).…”
