Abstract The aim of this paper is to analyze the occurrence of the so called day of the week effects in market return time series from the period of January 2003 to September 2013 (and additionally January 1999 to December 2002). The study focuses on four indices of the Warsaw Stock Exchange (WIG, WIG20, mWIG40 and sWIG80) and additionally five indices of major world stock exchanges (NIKKEI 225, DAX, CAC40, S&P 500, and IBEX). The main data sample was divided into three subperiods in order to determine whether or not the intensity of day of the week anomalies is constant in time. The study revealed a substantial number of the day of the week anomalies in earliest subperiods and very limited evidence of those effects in later ones, giving rise to the conclusion that the intensity of the day of the week anomalies is diminishing with time. The most common effect identified on the WSE was a positive Friday effect. The Monday effect often described in early literature on the subject matter seems to currently occur very rarely. The study also indicates that the day of the week effects were more persistent among stocks with smaller market capitalization on the WSE.

This research critiques Sumiyana (2007a) that is actually weak methodological research design. Sumiyana (2007a) investigates trading and nontrading periods return only, or it doesn’t split intra-day return into short interval period. Although Sumiyana (2007a) found strongly the phenomenon of the Monday effect, but it could not capture the inside occurrence in the intra-trading periods. This study examines the day of the week and Monday effect phenomena in the Indonesian Stock Exchange using intraday data in every 30 minutes interval. Samples of the data are the firms listed in LQ45. Sequentially, samples are filtered to stocks that actively traded in the Indonesian Stock Exchange based on trading frequency in observation period from January to December 2006. This study uses regression analysis with multiple dummies constructed by separating trading periods in every day into 12 return periods. This research finds that day of the week phenomena occur consistently in Indonesian Stock Exchange, but the occurrence are not evenly in the same day. In addition, this study concludes that Monday effect exists partially and incidentally only.

Small and medium-sized enterprises are the foundation for the development of each contemporary national economy. Their number affects macroeconomic indices of economies and directly translates into the labour market created by SMEs. This article aims to investigate the key conditionings behind the macroeconomic significance and legal factors of the financial market operation in Poland and the UK, with particular emphasis on the stock exchange as the fundamental element of the capital market. Both AIM and NewConnect are platforms dedicated to SMEs, which have been allowed easier access to this capital market segment by minimising mandatory legal conditions. This study analyses the number of listed companies and their capitalisation values in 1999–2015, covering: the rules of the financial market operation, with a special focus on the legal bases of the stock market operation in the economies investigated; legal conditions for the development of this economic segment; and a detailed analysis of the number of participants and capitalisation values achieved on the Warsaw and London Stock Exchanges, in particular AIM and NewConnect. This paper builds on source data from various annual reports and stock exchange publications drawn up and made available by stock exchanges and financial supervisors. The attempt to compare the indices and capacities of the WSE and the NC with the biggest European player is motivated by the fact that the Warsaw Stock Exchange is classified as the largest and most dynamically growing stock exchange in Central and Eastern Europe.

<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>

We develop a random financial time series model of stock market by one of statistical physics systems, the stochastic contact interacting system. Contact process is a continuous time Markov process; one interpretation of this model is as a model for the spread of an infection, where the epidemic spreading mimics the interplay of local infections and recovery of individuals. From this financial model, we study the statistical behaviors of return time series, and the corresponding behaviors of returns for Shanghai Stock Exchange Composite Index (SSECI) and Hang Seng Index (HSI) are also comparatively studied. Further, we investigate the Zipf distribution and multifractal phenomenon of returns and price changes. Zipf analysis and MF-DFA analysis are applied to investigate the natures of fluctuations for the stock market.

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.

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.

Data have shapes, and human intelligence and perception have to classify the forms of data to understand and interpret them. This article uses a sliding window technique and the main aim is to answer two questions. Is there an opportunity window in time series of stock exchange index? The second question is how to find a way to use the opportunity window if there is one. The authors defined the term opportunity window as a window that is generated in the sliding window technique and can be used for forecasting. In analysis, the study determined the different frequencies and explained how to evaluate opportunity windows embedded using time series data for the S&P 500, the DJIA, and the Russell 2000 indices. As a result, for the S&P 500 the last days of the patterns 0111, 1100, 0011; for the DJIA the last days of the patterns 0101, 1001, 0011; and finally for the Russell 2000, the last days of the patterns 0100, 1001, 1100 are opportunity windows for prediction

Purpose: The objective of this article is to assess how many entities have faced going concern problems and to identify what uncertainties may affect a going concern, especially during the COVID-19 pandemic. Methodology/research approach: The subject of the research was financial reports of com-panies listed on the main market of the Warsaw Stock Exchange in the following sectors: clothing and cosmetics, recreation and leisure, and transport and logistics. Thirty-three (out of 37) reports for the first half of 2020 were examined. We analysed the content of full ver-sions of the descriptive parts of financial statements, reports on the auditor’s review and management comment letters. Results: Nearly half of the surveyed entities that declared they were a going concern dis-closed going concern uncertainties. The pandemic affected the scope of disclosures present-ed in the reports. The variety of presentation styles and the selectivity of the place of the disclosure may hinder stakeholders when drawing conclusions. Research limitations/implications: Only three sectors were examined, and the sector analysis was conducted only in listed companies with complete and available reports. We analysed half-yearly reports that were reviewed by statutory auditors. The reports were analysed early in the pandemic. The article may be an inspiration for further research, including comparative research, in companies from the same and other sectors. The issue is vital, all the more so as the impact of the pandemic may change over time. Originality/Value: The article is a practical study of going concern disclosures during the pandemic. The study reveals the multifaceted nature and complexity of the issues related to continuation assessment.

Purpose: The aim of this article is to present a practical study of disclosures of events after the reporting period in the financial reports of listed companies from selected European countries. The paper presents the results of empirical research based on the source material in the form of financial statements for the year 2018 of listed companies included on the following stock exchange indices: DAX, PSI-20, OMX25, BUX, WIG20, which comprise companies listed on the stock exchanges in Germany, Portugal, Denmark, Hungary and Poland. Methodology/approach: The research sample includes 110 companies. Content analysis of full versions of individual financial statements was performed. Findings: The results show that listed companies comply with the International Financial Reporting Standards regarding the disclo-sure of events after the reporting period. The occurrence of such events in the business practice of com-panies listed on the Warsaw Stock Exchange is much more frequent than in other European countries. The results of the study also present the diversity of events disclosed by respective companies included in the sample after the reporting period. Originality/value: The research allowed us to compare the scope of financial reporting disclosures of events after the reporting period in companies listed on the Warsaw Stock Exchange and in other European companies. Comparisons of this kind have not yet been carried out in international empirical research, which makes this article all the more valuable.
