In this research we investigate whether quarterly earnings announcements are informative using awide sample of firms listed in the Spanish Stock Market (SIBE). We study the period comprised between thethird quarterly of 2002 and the fourth quarterly of 2003. We analyse whether abnormal returns are related tothe quarter in which the announcement is released, whether the announcement implies good or bad news forthe firm, the source of the information, the size of the firm and whether the firm is followed by analysts.Results show that quarterly earnings announcements are informative. We also obtain evidence of a possibleuse of insider information in the case of the announcements disclosed in the first quarterly of the year, thoserelated to small firms and to firms not followed by analysts. Se pretende comprobar si el anuncio de beneficios trimestrales tiene contenido informativo a través del estudio de la rentabilidad de títulos cotizados en el mercado continuo español para el período que abarca del tercer trimestre del 2000 al cuarto trimestre del 2002. Se analiza la presencia de rentabilidades anormales con la metodología del suceso y se incide en diferentes aspectos como son: el trimestre al que el anuncio hace referencia, el carácter positivo o negativo del beneficio, la fuente de información, el tamaño de la empresa y si se trata de una empresa seguida por analistas financieros o no. Los resultados obtenidos confirman la existencia de contenido informativo en los anuncios de beneficios trimestrales y presentan indicios de utilización de información privilegiada en la publicación de anuncios de beneficios correspondientes al primer trimestre del año y en el caso de empresas pequeñas y de empresas no seguidas por los analistas.
