Abstract

The objective of this paper is to observe the reaction of the Spanish Stock Market tothe signature of a collective agreement at a company level, measuring abnormal returns,abnormal volume and the associated risk on the day the information reaches the market.Bearing in mind that this type of agreement tends to increase salaries with respect to those ofthe sector, the initial hypothesis is that a company agreement incorporates negativeinformation with the expectation of abnormal negative returns and positive volume on theevent day. The arrival of new information not only modifies the average expectedperformance of the group of companies concerned, but also affects performance volatility. Itis expected, according to the variant of the traditional hypothesis of market efficiency, thatrisk and expected performance will vary in the same direction, depending on the sign of theinformation on the company involved. El objetivo de este trabajo es analizar la reacción del precio, volumen negociado y volatilidad de las acciones de las compañías cotizadas en el mercado continuo español ante la firma de un convenio colectivo a nivel empresa. Teniendo en cuenta que este tipo de convenios sesga al alza los salarios respecto a los del sector, la hipótesis de partida es que un convenio de empresa incorpora información que podría considerarse de forma negativa por los inversores. Esto conllevaría la venta de los títulos de tal empresa y una caída en su precio. Por tanto, esperamos encontrar incrementos en el volumen negociado acompañados de rendimientos negativos para estas empresas en torno a la fecha del acontecimiento. Los resultados generales de este trabajo confirman esta hipótesis, si bien se observan reacciones distintas dependiendo del sector al cual pertenezca la empresa. Por otro lado, la llegada de la nueva información que contiene la firma del convenio, podría afectar a la volatilidad específica de dichos rendimientos. Cabe esperar, según la variante de hipótesis tradicional de eficiencia de mercado, que si la nueva información reduce la incertidumbre sobre los flujos futuros de las empresas que firman el convenio, la volatilidad específica de las mismas sea menor a partir de esa fecha. Así ocurre con los datos de nuestra muestra.
