Effectiveness of Company Value Creation Based on Excess Market Value-Added Assessment

Abstract

This article aims to assess the usefulness of excess market value added to equity as an external measure of company value creation from the perspective of meeting shareholder expectations. This measure compares the expected value as an increase in stock exchange capitalisation in relation to return on equity, equivalent to its cost, decreased by this capital, in relation to the actually achieved level of capitalisation. This paper investigates relations with other external and internal measures. This research is based on measuring value creation in WIG30 Warsaw Stock Exchange companies in 2017–2023. The assessment of the research results was based on mathematical statistics tools, the density measure and the taxonomic measure of similarity. The study tested four hypotheses. The results of this research showed that the excess measure does not distort market information and can be used to assess the effectiveness of shareholder value creation, taking into account shareholder expectations. Secondly, the paper pointed to an unsatisfactory level of value creation in WSE WIG30 companies. The negative assessment of value creation management refers both to effectiveness and efficiency. Thirdly, shareholders continue to use classical financial measures despite the existence of a wide spectrum of value measures. Fourthly, the paper points to the lack of theoretical equality between the market value added (an external measure) and capitalised economic value added (an internal measure). The presented research contributes to unbiased assessments of whether or not shareholder value is simultaneously created and realised in increased share prices (capitalisation) to a higher degree than shareholder expectations. Up to now, no such research studies have been conducted for Polish and foreign capital markets. The research methodology has practical applications in expectations-based management.
