The aim of this study was to verify the short-term impact of financial variables on the corporate reputation perceived by investors. In the study we applied an approach from the field of business valuation assuming that corporate reputation perceived by investors is reflected in the difference between the valuation of a company by investors and its book value. Using panel data methodology, we analysed impacts of selected financial variables, representing company’s profitability, stability and its level of risk, on these differences in valuations of selected companies listed on the Warsaw Stock Exchange. Particularly, we chose companies operating in Construction and IT sectors to represent different types of activities (industry vs. services), which impacts also the diversity in the structure of their financial statements. In the study we used multiple regression models and analysis of contingency tables (chi-squared tests of independence and Yule’s coefficient of colligation). Our data suggest that there is a lack of strong short-term relations between analysed financial variables and corporate reputation. Nevertheless, we found different determinants of corporate reputation in the Construction sector (stability and profitability as well as their changes) and in the IT sector (stability, changes in profitability and the level of financial risk).

W artykule przedstawiono badanie zależności między kapitałem rady nadzorczej a wyceną spółek. Kapitał rady nadzorczej jest wskaźnikiem oceny efektywnego nadzoru i doradzania przez radę zarządowi. Zależność między kapitałem rady nadzorczej a wynikami została zbadana na poziomie analizy inwestycji w portfele inwestycyjne. Skonstruowano 5 alternatywnych portfeli na bazie walorów 14 spółek, dla których odnotowano najwyższy poziom kapitału rady nadzorczej w populacji wszystkich firm giełdowych. Wykorzystano analizę skumulowanych stóp zwrotu z portfeli, zobrazowano ich położenie względem granicy efektywnej wg teorii Markowitza, a także przeanalizowano ich zachowanie względem rynku za pomocą modeli regresji. Wyniki analiz upoważniają do stwierdzenia, że została zaobserwowana pozytywna zależność dla inwestycji w portfele walorów skonstruowanych z akcji firm o najwyższym poziomie kapitału rady nadzorczej.

The article presents the relationship between supervisory boards’ capital and the value of firms. Such capital is an indicator of efficient supervision and advice offered by supervisory boards to management boards. The link between supervisory boards’ capital and performance is examined by means of an analysis of investment in investment portfolios. Five alternative portfolios have been designed based on the value of 14 companies that had the highest supervisory capital in the population of all listed companies. Cumulative returns on portfolios are analysed, their position relative to the efficient frontier according to Markowitz’s theory is illustrated, and their behaviour towards the market is examined using regression models. The analysis results show a positive correlation for investments in portfolios consisting of stocks of companies with the highest supervisory capital.
