Abstract

Resumen:Este artículo analiza el efecto de los anuncios de cambios en el control corporativo (Ofertas Públicas de Adquisición - OPA) sobre el precio de cotización en Bolsa de Endesa, Hidrocantábrico y Scottish Power y el impacto que estos acontecimientos tienen sobre los rendimientos de los competidores más cercanos a la empresa OPAda. Por medio de la metodología de estudio de acontecimiento", empleando modelos GARCH y MCO, se encuentra que las OPA lanzadas sobre estas empresas hacen que ellas presenten rendimientos anormales positivos, estadísticamente significativos a un nivel del 1%. Los resultados también sugieren que en industrias con alto poder de mercado, el anuncio del lanzamiento de una OPA tiene un impacto positivo estadísticamente significativo sobre los rendimientos de los competidores más cercanos a la empresa OPAda.Abstract:This paper analyzes how announcel changes in the corporate control (takeover) of Endesa, Hidrocantábrico and Scottish Power affect their stock market returns and the impact that these events have on the stock market returns of competitors of the target firm. Using an "event study" methodology we find that takeovers positively and significantly affect at the 1% level, the stock market return of the target firm. Results are robust across several econometric specifications as GARCH and MCO models. Also, the results suggest the announcement of the launching of a takeover positively and significantly affects the stock market return of the target firm´s competitors in industries with high market power."
