Abstract Beta parameter is one of the commonly used measures of the investment risk of individual stock or portfolio. It plays a crucial role in modern portfolio theory particularly in management of financial investment portfolios. In the field of beta parameter, numerous studies have been conducted, especially beta properties stability in the context of the stock market cycle phases, measuring frequency of rate of return, and the length of a sample period. There are much fewer studies concerned beta parameter in the countries of Central and Eastern Europe which have undergone systemic transformation at the end of the previous century. From a scientific point of view, it is interesting to know how the beta parameter behaves in these countries. The main goal of this article is to examine the beta parameter stability over bull and bear market conditions on the Warsaw Stock Exchange. The paper presents an analysis of beta stability for 134 stocks of the largest companies listed at the WSE during years 2005–2013. To verify statistically the hypothesis of beta parameter stability, we used monthly returns in the Sharpe’s single-index model. In the first part of the article, we present a brief review of the literature and methodology of the study, while in the second part, the obtained results and conclusions are shown.

Agricultural Food

The food sector is one of the most important and fastest growing branches of the Polish economy. It employs almost 15% of all employees employed in the industry. Polish manufacturers are characterised by high competitiveness both in the EU and in the world. The macroeconomic environment in recent years has been relatively stable for the development of the food industry production in Poland, but the dynamics of agricultural-food products has experienced a slight slowdown. There were also fluctuations in profitability ratios in the sector, which may have been somewhat alarming for the investors. The article attempted to evaluate the investment attractiveness of 24 joint stock companies in the food sector, representing various industries, listed on the Warsaw Stock Exchange. The Taxonomic Measure of the Attractiveness of Investments (TMAI) and the company rankings were created for the years 2013 – 2016. The results showed that the Wawel and Astarta companies were at the top of the rankings in the studied years, representing the confectionery and the sugar sector, and the Żywiec company from the beer industry. The meat and fish processing companies were more or less centred on the scale. The companies KSG Argo, Milkiland, Wilbo, Pepees and Pamapol involved in the agricultural-food production and processing received the poorest evaluations of the investment attractiveness. The synthetic taxonomic TMAI measure makes it possible to build company rankings within the analyzed group, from the point of view of the assessment of the financial condition and investment attractiveness of the surveyed companies. It can provide additional help in assessing the company’s situation, e.g., for the investors.

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.
