The aim of the article is to analyse the change in the quotations of Polish listed companies, which change the stock exchange index as part of the periodic change in the composition of the WIG20, mWIG40 and sWIG80 stock market indices. The research methodology uses abnormal return (AR) based on daily logarithmic rates of return of Polish listed companies and daily logarithmic rates of return on the stock market indices (WIG20, mWIG40, sWIG80). In this way, they defined the relative strength of listed shares in relation to the stock indices revision a month before the composition of the stock index, when the drawn up list of companies is changing the composition of the index. In addition, the relative strength of quoted shares in relation to stock exchange indices after the revision of the composition of the stock exchange index in the short-term (one month) and medium-term perspective (six months) was examined. The research was based on quarterly changes in the composition of stock exchange indices in the years 2010-2015. The analyses carried out indicate the existence of positive surplus stock returns a month before the change in the stock index. The average number of quotes of these companies above the stock market index at the time amounted to +0.52 percentage points. In turn, the average increase in the prices of the debuting companies in the new stock exchange index within 6 months after their flotation it amounted to +0.97 percentage points over the benchmark (WIG20, mWIG40, sWIG80).

This paper is aimed at presenting application of bootstrap interval estimation methods to the assessment of financial investment’s effectiveness and risk. At first, we give an overview of various methods of bootstrap confidence interval estimation, i.e. bootstrap-t interval, percentile interval and BCa interval. Then, bootstrap confidence interval estimation methods are used to estimate confidence intervals for the Sharpe ratio and TailVaR of the Warsaw Stock Exchange sectoral indices. The results show that the bootstrap confidence intervals of different types are quite similarly positioned for each of the analysed index and measure. Taking into the account the locations of confidence intervals for both the Sharpe ratio and TailVaR, the real estate sector tends to be the most advantageous from the investor’s viewpoint.

The paper employs a threshold regression framework conditioned by two COVID-19 related proxies, to investigate whether Bitcoin and Ether exhibit short-term safe haven or diversiefir features for stock and bond markets. Both cryptocurrencies fulfil a diversiefir role for the responsible investments represented by sustainable stock market indices, a safe haven role for major bond markets and a mixed role for a selection of representative stock market indices. Furthermore, in times characterized by an increasing number of COVID-19 daily cases or deaths the statistical relationship between both cryptocurrencies and the main nfiancial market determinants weakens.

Wśród mediów finansowych oraz szerokiego grona inwestorów można się spotkać ze stwierdzeniem, że rynek NewConnect (NC) nie jest atrakcyjnym miejscem do dokonywania inwestycji, że na NC dominują spółki groszowe o niskiej płynności akcji, że indeks obrazujący zachowanie kursów akcji emitentów notowanych na tym rynku znajduje się w wieloletnim trendzie spadkowym. W niniejszym artykule podjęta została próba polemiki z powyższym poglądem, a autorzy postawili sobie za cel wskazanie nowych rozwiązań, których wprowadzenie mogłoby w istotnym stopniu poprawić odbiór rynku NewConnect wśród wszystkich grup uczestników tego rynku. Rozwiązania te to wskaźnik mający za zadanie dokonywanie pomiaru stopnia rozwoju spółek z segmentu NC Focus (NCGI-Focus) oraz wskaźnik mierzący stopień zmian wartości rynkowej emitentów z tego samego segmentu (NCFocusValue). Autorzy referatu przedstawili nie tylko zarys metodologiczny, lecz także poparli zasadność wprowadzenia obu miar wynikami empirycznymi odnoszącymi się do okresu funkcjonowania segmentu NC Focus.

It is common opinion among the financial media and a wide range of investors in Poland that the NewConnect (NC) market is not an attractive place for investments. The NC market is dominated by penny companies with low liquidity of shares that encounter significant problems with fulfilling information obligations. This paper disputes this view by referring to companies from the NewConnect market. The authors aim at identifying new solutions, to improve the perception of the NewConnect market among all groups of its participants. These include the construction of new NC indicators: i) an indicator designed to measure the development level of companies from the NC Focus segment (NCGI-Focus) and ii) an indicator measuring the degree of changes in the market value of issuers from the same segment (NCFocusValue). This is supplemented by empirical results.

The article also includes a comparative analysis of the results of indexes RESPECT, WIG20, mWIG40 i sWIG80, and also WIG-BANKI, WIG-BUDOW, WIG-CHEMIA, WIG-DEWEL, WIG-ENERG, WIG-INFO, WIG-MEDIA, WIG-PALIWA, WIG-SPOZYW, WIG-SUROWC, WIG-TELKOM. Analysis of the global index was based on data obtained from the Datastream database, the data to the comparison RESPECT Index with other indices came from the databases of Warsaw Stock Exchange and Parkiet The newspaper of the Stock Exchange. The data being presented show that the performance indices (trend) in the chosen periods behave similarly, but their efficiency varies. Not all index's values for two of the examined periods were characterized by growth. The results also show that investments in socially responsible businesses in selected capital markets are not associated with resistance to the collapse of the stock market. Information about the participation of the company in the index is not a guarantee to the investor that the investment in the company in question will bring a reasonable return.

W artykule przytoczono dane wskazujące na obserwowany trend dotyczący wzrostu znaczenia społecznej odpowiedzialności biznesu. Istotne z punktu widzenia tego wzrostu było zestawienie funkcji, jakie pełnią obecnie giełdowe indeksy CSR/SRI/ESG. Głównym celem niniejszego artykułu jest analiza zachowania się wybranych światowych indeksów giełdowych spółek społecznie odpowiedzialnych (DJSI World, DJSI North America, FTSE4GOOD Global, MSCI KLD 400 Social, CALVERT Social (CSI), MSCI World ESG, STOXX Europe Sustainability, DJSI Europe). Opracowanie obejmuje także analizę porównawczą wyników indeksów RESPECT, WIG20, mWIG40 i sWIG80, a także WIG-BANKI, WIG-BUDOW, WIG-CHEMIA, WIG-DEWEL, WIG-ENERG, WIG-INFO, WIG-MEDIA, WIG-PALIWA, WIG-SPOZYW, WIG-SUROWC, WIG-TELKOM. Analiza dotycząca światowych indeksów była oparta na danych pozyskanych z bazy Datastream, natomiast dane do części publikacji związanej z porównaniem indeksu RESPECT z innymi indeksami warszawskiej giełdy pochodziły z serwisów Giełdy Papierów Wartościowych w Warszawie oraz Parkietu Gazety Giełdy. Zaprezentowane dane wskazują, że wyniki światowych indeksów (trendy) w badanych okresach zachowują się podobnie, jednak ich efektywność jest zróżnicowana. Nie wszystkie wartości indeksów w badanych dwóch okresach charakteryzowały się wzrostem. Otrzymane wyniki pokazują również, że inwestycje w przedsiębiorstwa społecznie odpowiedzialne na wybranych rynkach kapitałowych nie są związane z odpornością na załamania na rynku akcji. Informacja o udziale spółki w indeksie nie jest dla inwestora gwarancją, że inwestycja w daną spółkę przyniesie odpowiednią stopę zwrotu.
