Panelowa baza danych o spółkach notowanych na Giełdzie Papierów Wartościowych w Warszawie dla potrzeb analiz finansowych
A Panel Database of the Companies Listed on the Warsaw Stock Exchange for Financial Analysis

Summary/Abstract: Any verification of financial hypotheses (theories) requires appropriate data. Such a requirement is met by panel data, which make it possible to use observations of many companies in many periods. The paper discusses the properties of the unbalanced panel of 112 domestic companies (excluding banks) which was constructed by the authors. At the end of 2019 these companies had been listed for at least 3 years, i. e. they had entered the WSE no later than December 31, 2016. The companies in the panel were described using 76,000 numerical values. This does not exhaust the possibilities offered by the panel because, using the variables in the panel, one can create, depending on one’s research needs, subsequent variables.
