Abstract

There are a lot of theoretical and empirical literature of models of price formation in securities markets, based on the relationship between the expected return on assets and different measures of its risk. Using monthly returns for size-based portfolios from January 1982 to December 1998 we investigate the empirical specification of some multi-factor models in the Spanish stock market. The work has a double aim: to analyze if the betas of the factors considered in each model have a significant role in the explanation of the returns, and to compare the performance of the different models. We consider three static models: the standard CAPM, the three factor model by Fama and French and an APT with asymptotic principal components as risk factors; and two conditional models: a conditional CAPM and the intertemporal model by Campbell (1993). We find that conditional models do a better job than static models. Este trabajo consiste en la contrastación empírica de cinco de los modelos de factores más representativos en materia de valoración: el CAPM estándar, el modelo de tres factores de Fama y French, un CAPM condicional, el modelo intertemporal sin consumo de Campbell y un APT general en el que los factores se aproximan mediante la técnica de los componentes principales asintóticos. Aunque el objetivo del estudio reside en la comparación y ordenación de tales modelos en base al buen ajuste a los datos de nuestro mercado bursátil, en la primera parte del trabajo se realiza una estimación tradicional de las primas de riesgo de los factores que considera cada modelo para analizar su significatividad. Después, la estimación por el Método Generalizado de los Momentos, utilizando como matriz de ponderaciones la propuesta por Hansen y Jagannathan (1997), nos permitirá la comparación entre los distintos modelos. Los resultados de ambas partes son consistentes entre sí e indican un mejor comportamiento de los modelos condicionales.
