Subject and purpose of work: This study investigates the effectiveness of equity investment in
renewable energy companies. The aim of the research is to compare the effectiveness of investing
in the stocks of companies from the conventional and renewable energy sector on the Warsaw
Stock Exchange.
Materials and methods: The research material consisted of the stock prices of selected energy
companies listed on the Warsaw Stock Exchange’s Main Market and NewConnect. Representative
investment portfolios were created and their average monthly logarithmic rates of return, standard
deviations and Sharpe ratios for the period 2013–2020 were examined.
Results: The portfolios of renewable energy companies were characterised by higher risk, but also
higher average returns; as a result, they achieved higher risk-adjusted efficiency ratios than the
portfolios of conventional energy companies.
Conclusions: Shares in renewable energy companies, despite a significant risk, can be an attractive
form of investment, which is crucial for privately financing the energy transformation in Poland.
