PIOTROSKIS FUNDAMENTALA SIGNALER;ÄR DE VÄRDERELEVANTA?
EN NUTIDA STUDIE PÅ STOCKHOLMSBÖRSEN
This study aims to evaluate the value relevance of Piotroski?s (2000) nine fundamental signals. In order to do this, the signals are tested on the OMX Nordic Exchange Stockholm between the years 2003 and 2009. The hypotheses of the study are whether the signals are value relevant and if the value relevance has changed. To test this, a Chi-square test and a regression are used. The tests show that some signals are value relevant, and that some are not. We also find evidence for a change in the value relevance during the years of the observation. Some explanations to why the value relevance has changed is also discussed.
