Polish Journal of Management Studies

Vol. 24, No. 2

414--430

The COVID-19 pandemic has forced changes in the global economy and caused the world to focus on the IT sector. The goal of the article is to determine the influence of the pandemic on the investment effectiveness in the shares of IT sector companies. The investment effectiveness during the pandemic was analyzed on the example of investments in selected stocks of companies listed on the WSE in the years 2019-2020. Returns on selected stocks and risk-adjusted measures of profitability based on the Capital Asset Pricing Model (CAPM) were used, and statistical verification of the quality of asset management in relation to the performance of the WIG index was carried out. The results show that during the pandemic, the effectiveness of investments in the shares of the Polish IT sector differed significantly from the WIG investment portfolio. This information can be discounted in the management process at the market risk estimation stage.

Pandemia COVID-19 wymusiła zmiany w światowej gospodarce i spowodowała, że cały świat przeniósł uwagę na sektor IT. Celem artykułu jest określenie wpływu pandemii na efektywność inwestycji w akcje spółek sektora IT. Efektywność inwestycyjną w czasie pandemii analizowano na przykładzie inwestycji w wybrane akcje spółek notowanych na GPW w latach 2019-2020. Wykorzystano stopy zwrotu wybranych akcjach i skorygowane o ryzyko miary rentowności oparte na modelu wyceny aktywów kapitałowych (CAPM). Przeprowadzono statystyczną weryfikację jakości zarządzania aktywami w odniesieniu do indeksu WIG. Wyniki pokazują, że w czasie pandemii efektywność inwestycji w akcje polskiego sektora IT znacznie różniła się od portfela inwestycyjnego WIG. Tego typu informacje mogą być dyskontowane w procesie zarządzania na etapie szacowania ryzyka rynkowego.

Power engineering is one of the key areas of sustainable development. Many countries create new concepts of environmental safety management and modify their energy systems to be in line with the goals of sustainable development in the EU. Sustainable development indicators can be a tool for monitoring the set goals of environmental safety management. The aim of the article is to assess the environmental safety management of the energy sector in Poland in relation to EU as well as presenting the concept of sustainable energy development and indicators used to assess the development of energy in the following dimensions: social, economic and ecological. The indicators used to assess the sustainable development of energy in the following dimensions were compared: sustainable consumption and production, marking the production and consumption of energy; organizations and sites with eco-management and audit scheme (EMAS); registration climate change, marking GHG emissions and the share of renewable energy in gross final energy consumption; sustainable transport, marking the energy consumption of transport relative to GDP. The article will test the hypothesis that the structure of obtaining energy in Poland and the tempo of change in this respect differ from the EU average.
