The subject of this publication is an analysis of the sentiment of stock exchange investors in terms of making investment decisions in the energy sector of the Polish stock exchange. The investment mood is considered in the context of the possible impact of weather factors on investment decisions. Possible effects are verified in relation to the rates of return and the volume of trading of energy sector entities. The analysis is carried out both in terms of co-integration analyses as well as in econometric terms, in the cross-section of classic OLS models or causality analysis using VAR vector autoregression models. The main purpose of the issues discussed is the problem of indicating (illustrating) the presence or absence of mutual relations between weather factors and the stock market in terms of the methods considered.

Abstract In the modern portfolio theory investment risk plays a crucial role. It is the subject of numerous studies and publications, in particular in relation to the management of investment portfolios. Commonly used measure of investment management in equities is a beta parameter, which is used to estimate individual stock risk and portfolio risk. In particular, numerous studies the subject of which are the beta parameter properties such as stability in the context of the stock market cycle phases, intervalling effect, length estimation sample etc. The main objective of this paper is to investigate the intervalling effect on the beta parameter. The empirical analysis is carried out for the 33 largest companies of the Warsaw Stock Exchange (WSE) on a sample from the years 2005 to 2012 on the basis of daily, weekly and monthly rates of return. Statistical verification of the hypothesis of the importance of the frequency measuring the return of shares will be based on the single-index Sharpe’s model.

The main aims of this article are to verify whether rates of return might be determined by stock prices and to evaluate low price anomaly on the example of Warsaw Stock Exchange. The author states that cheap assets characterized by nominally lower prices are more attractive to buy and bring higher profits in comparison to assets described as expensive. In order to verify the hypothesis, database of 13789 quotations from 1.07.1999 to 30.12.2013 was created. The sample was divided into three groups – cheap, average, and expensive stocks. Finally, the statistical analysis was conducted using 2924 records including only cheap and expensive units. Statistical analysis confirms that low–priced assets generate higher profits and lower losses.

Recent researches on behavioral finance have tested for, among others, evidence for the relations between weather, investors’ mood, and investment decisions. Many of the researches related to the influence of some weather factors, such as sunshine duration on stock exchange returns, but there is no complex research taking into account a wide group of weather factors determining investors’ mood. The main goal of the article is to verify the influence of weather factors on basic market parameters of energy sector companies quoted on the Warsaw Stock Exchange. Rates of return, trading volumes, and values of trading volume are taken into account during the research. All analyses are based on econometric models assuming the existence of typical problems of estimation such as: autocorrelation of residuals, heteroskedasticity, or abnormality of residuals. The best approximation of models was obtained for GARCH (Generalized Autoregressive Conditional Heteroskedasticity) type models.

If corporate social responsibility (CSR) is expected to work efficiently, there should be a standardised approach for implementation of the CSR concept for all businesses, including companies operating in the energy sector. Although many companies declare compliance with CSR standards, further investigation should be undertaken to evaluate if and how those standards have been applied in practice. The aim of this research is to examine the level of standardisation of the CSR activities within Polish energy companies and explore the good practices developed by those companies. The Polish energy companies have been selected for the investigation as the literature review we conducted demonstrates that there is limited research in this area and there is a knowledge gap regarding how Polish energy companies apply CSR regulation in practice. To accomplish the stated aims, the following research questions were developed: (1) What is the essence of applying the CSR concept in Polish energy companies, and at what level of development is the concept applied? (2) To what extent do Polish energy companies have a common approach to the CSR concept, and in what areas are there differences? (3) To what extent have Polish energy companies applied global CSR standards and solutions? (4) Is there a gap between the declared measures of CSR and their actual implementation in Polish energy companies? The research methodology of this study is based on a systematic literature review of the sources acquired from databases such as ProQuest, Emerald, SCOPUS and the Jagiellonian University Library. The multiple case study approach was identified as the most suitable research tool. Companies for the study were selected according to their affiliation to the energy sector and listing on the main market of the Warsaw Stock Exchange. These two assumptions allowed us to base this study on the largest Polish energy companies that have international status. Six areas of CSR annual report disclosures have been identified and used for the investigation and analysis. This research looks at similarities and difference between these six aspects of CSRs disclosed by Polish energy companies. The investigation allows us to conclude that the top three energy companies use similar tools to build their CSR strategies: formalised CSR concept, published CSR reports, disclosure of CSR information on the company website, CSR related activities offered to stakeholders, obtained CSR certificates, and CSR awards. This indicates the existence of a standardised approach to CSR across Polish energy companies.

Abstract Research purpose: Seven of 10 companies that have won the Polish Forbes edition Merge & Acquisition 2018 Ranking are listed on Warsaw Stock Exchange. The aim of the conducted research was to test if the biggest acquisitions have an impact on stocks value and is it possible for typical investor to create extra profit by using knowledge of acquisition based on public information. Design/Methodology/Approach: Using data from Warsaw Stock Exchange (quotations), typical measures such as rate of return, standard deviation (risk), correlation and transaction volume changes were calculated. Each of the case results obtained for the company was compared with the result for stock market indexes: WIG (Warszawski Indeks Giełdowy – main WSE index), WIG20 (WSE sub-index of the 20 largest companies), mWIG40 (WSE sub-index of 40 medium companies) and sWIG80 (WSE sub-index of 80 small companies). In addition, the outcomes were confronted with public news (from WSE Electronic System for Information Transfer). Findings: Conducted research has shown that generally successful finalisation of acquisition results in changes of stock prices behaviour. Unfortunately, observed reactions were not the same. Acquisitions induced both increases and decreases in stock prices; there was also no rule in case of risk change. Generally, acquisitions and merges had rather good influence in banking sector (which is still concentrating), but there was no common reaction in other sectors. Originality/Value/Practical Implications: The results will be useful for investors acting on Warsaw Stock Exchange, especially for individual investor who are not able to carry out detailed analyses. The research provides results including possible pre-effects and after-effects of making big acquisition by a large company. The negative market reactions were also shown.

<p>Earnings management in Polish listed companies was the subject of only several studies, mainly theoretical, but none of them is related to earnings management to meet analysts’ expectations. The aim of the paper is to detect any signals of earnings management to achieve zero or small positive earnings surprises. The sample comprises 609 observations from years 2012-2014 related to medium size companies listed at Warsaw Stock Exchange. Distribution of scaled annual earnings surprise (difference between realized and forecasted earnings scaled by beginning total assets) is analyzed. It contains unusually high frequency of small positive surprises. If the module of earnings surprise is small it is more probable that the real value was higher than the forecast - meeting or beating the forecast, so small positive earnings surprises are more probable than negative. If the module of earnings surprise is high it is more probable that the forecast of income was higher than the real value - neither meeting nor beating the forecast. Results are not sensitive to the choice of earnings surprise metric.</p>

This paper presents new methods and models for forecasting stock prices and computing hybrid models, combining analytical and neural approaches. First, technical and fractal analyses are conducted and selected stock market indices calculated, such as moving averages and oscillators. Next, on the basis of these indices, an artificial neural network (ANN) provides predictions one day ahead of the closing prices of the assets. New technical analysis indicators using fractal modeling are also proposed. Three kinds of hybrid model with different degrees of fractal analysis were considered. The new hybrid modeling approach was compared to previous ANN-based prediction methods. The results showed that the hybrid model with fractal analysis outperforms other models and is more robust over longer periods of time.

The study posed a research question: did the situation caused by COVID-19 affect the economic position of energy companies? The aim of the study is to investigate the impact of the situation of the epidemic state introduced in 2020 on the activities of the efficiency of energy sector companies. The subject of the research will be the ten largest Polish power plants in terms of electricity production, including four capital groups to which they belong. Financial data from 2014 to 2020 will be used for the research. To test the effectiveness, the tools of the ratio analysis will be used. The analysis of the financial statements in terms of investments in manufacturing activities confirms the hypothesis that companies investing in new solutions and technologies will be best prepared for an exceptional situation. The results of the research show that those capital groups which in the period preceding the outbreak of the epidemic made the largest investment outlays and at the same time their financial ratios and market valuation on the Warsaw Stock Exchange were the highest, they also achieved the highest financial results during the pandemic—they had the most favorable economic situation.

The main purpose of this article is to determine the impact of changes in the fair value of assets and liabilities on the overall net result of selected banks listed on the Warsaw Stock Exchange. The research covered the consolidated financial statements of five banks, for the years 2014-2018. Methods of analyzing the literature on the subject, financial statements, and legal acts, including selected IFRS, were used. It has been shown that, on the one hand, fair value revaluations have a significant impact on the financial result of the described entities; on the other hand, the fair value in these entities is determined mainly at the 1st level of the hierarchy. This means that the basis for determining the fair value is observable prices on the market, and that the impact of subjective estimates on the financial result is small.
