Abstract

The objective of this study is to contrast the effects of market share and industrial conditions on the performance of companies, basing our evaluations on their stock value and their resources. The basichypotheses are: i) That an increase in market share that isn't supported by changes in the fundamental resources of the firm does not generate value (performance); and ii) that industrial conditions influence a firm's performance. The methodology uses a recursive model taken from Financial Theory to estimate theannual changes in the firms' value (which reflects the influence of the fluctuations in their resources), and the effects that industrial conditions have on their performance. The method also employs other statistical techniques to demonstrate the relationship between the annual fluctuations in a firm's value and the annual changes in its market share. The novelty of this approach is that it allows us to examine the interactions, one by one, that occur among the different firms of a given sector. Based on the results obtained from the application of this model to nine companies in the Spanish construction sector, we demonstrate that an industry effect does exist, but that there isn't sufficient statistical basis to demonstrate that the gains in market share of a given sector in which the firms experience no changes in their comparative resource situations, do not generate excessive profits. El objetivo del trabajo es contrastar los efectos de la cuota de mercado y de las condiciones de la industria sobre los resultados de las empresas, tomando como punto de partida las cotizaciones bursátiles así como los recursos empresariales. Las hipótesis de partida son: i) que los incrementos en la cuota de mercado que no vienen apoyados por cambios en los recursos de las empresas no generan valor (resultados); y ii) que las condiciones de la industria influencian los resultados. La metodología aplicada utiliza un sistema recursivo de la Teoría Financiera para estimar los cambios anuales en el valor de la empresa (refleja la influencia del cambio en los recursos), y los efectos de las condiciones de la industria sobre los resultados; así como diversas técnicas estadísticas para demostrar la relación entre la variación anual en el valor de la empresa y los cambios anuales en la cuota de mercado. Como novedad, el procedimiento permite examinar las interacciones, una a una, entre las empresas. Como resultado de la aplicación a nueve empresas constructoras españolas, se demuestra que existe un efecto industria, pero no hay suficiente base estadística para concluir que los incrementos en la cuota de mercado de un sector, entre cuyas empresas no se producen cambios en sus posiciones relativas de recursos, no generan excesos de beneficio.
