Abstract

Este documento resume 1.466 respuestas a una encuesta por e-mail realizada a directivos de empresas y a profesores de finanzas europeos. 1.143 personas utilizan rentabilidad exigida y 824 utilizan betas para calcularlas. La mayoría (717) de estas 824 personas justifican las betas que utilizan con regresiones, webs, bases de datos, libros o artículos. Solamente 70 personas justifican las betas que utilizan empleando únicamente el sentido común. La proporción de directivos que utilizan rentabilidad exigida pero no utilizan betas para su cálculo (44%) es muy superior a la de los profesores (8%). La proporción de directivos que utilizan sólo el sentido común para justificar las betas que utilizan (15%) es muy superior a la de los profesores (2%). Sorprende que, con los problemas que presentan las betas calculadas por regresión, un gran porcentaje de los profesores y directivos todavía las utilicen para calcular la rentabilidad exigida. La mayoría admite que hay muchos problemas en su determinación, pero continúan enseñándola y utilizándola por diversas razones: "ha obtenido el Premio Nobel en Economía", "se utiliza mucho", "permite defender una valoración, impresionar a la dirección y parecer un gurú financiero"
