Opis:
The risk parity portfolios are characterized by equally weighted contributions of all assets. Very often, the idea of risk parity is considered as a special type of the diversification strategy. This approach became very popular among investors after the last economic crisis, when many portfolios perceived as well-diversified suddenly became undiversified portfolios. Usually, risk parity is calculated for individual stocks. In this article, the method of estimating risk parity portfolios for grouped stocks is discussed. The presented model is applied to selected stocks belonging to different groups (sectors, size of companies) and quoted on the Warsaw Stock Exchange. The main goal of the empirical research is the analysis of the risk parity portfolios calculated for the groups of stocks and also for individual stocks. Additionally, the risk parity portfolios are compared with the naive portfolios and minimum variance portfolios. All portfolios are compared according to the risk, rate of return, Sharpe ratio and the future profits.

Opis:
The classical models used for the construction of an investment portfolio do not take into account the fundamental values of the companies in question. The model of a fundamental portfolio adds this dimension to the classical criteria of profitability and risk. It is assumed that an investor selects stocks according to their attractiveness measured by some fundamental values of companies. In the paper the authors propose an analytical solution of the optimization problem of constructing a fundamental portfolio and present empirical examples of the calculation of fundamental portfolios of stocks listed on the Warsaw Stock Exchange.
Klasyczne metody wyboru portfela inwestycyjnego nie biorą pod uwagę wartości fundamentalnej spółek. Model portfela fundamentalnego dodaje ten wymiar do klasycznych kryteriów zyskowności i ryzyka. Zakłada się w nim, że inwestor wybiera spółki według ich atrakcyjności inwestycyjnej, mierzonej za pomocą pewnych wskaźników fundamentalnych. W artykule przedstawiono propozycję analitycznego rozwiązania problemu optymalizacyjnego konstrukcji portfela fundamentalnego. Zaprezentowano też przykłady wyznaczania tą metodą portfeli fundamentalnych złożonych z akcji spółek notowanych na Giełdzie Papierów Wartościowych w Warszawie.

Opis:
Diversification is one of the most important elements considered in the process of the construction of investment portfolios. A special role is attributed to the diversification in periods of rapid changes in the financial markets. In the article, the problem of international diversification was analysed on the example of selected European, American and Asian markets. The level of diversification was assessed by various measures: Portfolio Diversification Index, Rao’s Quadratic Entropy and Diversification Ratio. In the study diversified portfolios were compared. These portfolios were constructed for the data from the periods before, during and after the last economic crisis. The conducted research showed that European markets were most diversified, regardless of the nature of the analysed period. The study also showed that strongly interrelated countries did not necessarily have strong influence on diversification.

Opis:
The subject of portfolio investment seems particularly significant given that the current fluctuations on international financial markets make it necessary to perform an analysis of their causes and effects. It seems reasonable to make considerations regarding the direction of the flow of portfolio investment in the twentieth and twenty-first century. This article presents theoretical considerations concerning the characteristics and effects of the flow of portfolio investment in the global economy and an analysis of flow directions in the years 1960-2015. These considerations are based on data of the International Monetary Fund and the World Bank, which collate net inflows of the portfolio investment to particular countries in the indicated period. Our considerations show the links between the financial markets of countries and regions, together with the general tendencies of movements of capital at the time of crisis and the stabilization periods of global financial markets. The article shows the link between the financial markets of individual countries, together with the general trend of movement of capital in the period of crisis and the stabilization of financial markets

An important question on the battlefield of product innovation is how to invest effectively limited resources in research and development and product innovation process? Useful in solving this problem are various methods of portfolio management. Today’s new product designs will determine the product range and market profile of the company in the future. Product portfolio renewal rate increases in a variety of companies in various economic sectors. Already about 50% of current sales come from new products launched in the past five years (approximately 30% of sales come from new products launched in the last three years). Managers who can optimize their investments in R & D and product innovation, have a much better chance of winning in the long run. But how to manage a portfolio of product innovations projects in order to achieve a sufficient and satisfactory return on investment? There are many different methods and tools to gain valuable information, but even their use does not give easy answers. In this article we shall identify the modified methods, objectives, areas and problems of new products portfolio management.

Opis:
The aim of this article is to examine the flow of portfolio investment in the 21st century in the further use of the Lucas paradox observed in the world economy in the twentieth century. Portfolio investments are perceived in the literature and empirical research as less significant, while both their size and importance to the development of capital markets are usually only indicated. Data for the study were obtained from the balance of payments of individual countries and groups of countries, as well as data on the size and level of development of capital markets in these groups. The course of this research confirmed the importance of the flow of capital in the form of portfolio investments in the global economy. This has shown the further occurrence of the Lucas paradox, also in portfolio investment. It shows the weakness of the capital markets of LDCs in conjunction with the insufficient inflow of portfolio investments. The originality of the article lies in the combination of portfolio investments and determinants of the attractiveness of individual capital markets for investors in international financial markets. The small inflow of portfolio investments is both the cause and the consequence of the insufficient level of development of capital markets in the least developed countries (LDC). Hence the need to make a diagnosis and to build paths of development of such markets based on the experience of more developed countries, in order to adapt them to attract and retain capital in the form of portfolio investments

The main aim of the article is to conduct the analysis of the different levels of development of Indonesia and Singapore capital markets between 1995 and 2015 and show that in both cases a sudden stop occurs, especially in the period of regional and global financial crises. However, it is possible to see a faster return to stabilization in the developed market, and therefore better opportunities for attracting foreign capital. International capital flows in this article shall be construed as a shift of capital across national borders, recorded in the account balance of payments.

Opis:
Głównym celem tej pracy jest wskazanie możliwości zastosowania świec japońskich w analizie portfelowej. W literaturze przedmiotu znajdujemy już opisy świecy japońskiej za pomocą skierowanej liczby rozmytej. W przedstawianym artykule jeden z tych modeli świecy został wykorzystany jako oszacowanie nieprecyzyjne określonej wartości bieżącej. Zastosowany model opisu świecy japońskiej został jednoznacznie określony. W ten sposób wartość bieżąca pojedynczego instrumentu finansowego jest dana jako skierowana liczba rozmyta. Wykorzystano tutaj zrewidowaną definicję skierowanej liczby rozmytej. Zorientowana wartość bieżąca portfela jest przedstawiona jako liniowa kombinacja świec japońskich składników portfela. Dzięki takiemu ujęciu portfela aktywów finansowych pokazano możliwość zastosowania świec japońskich do analizy portfelowej. W podsumowaniu wskazano na istniejące zorientowane rozmyte indeksy finansowe mogące znaleźć zastosowanie w tak ujętej analizie portfelowej.
The main purpose of this work is to show the possibility of using Japanese candles in portfolio analysis. In the subject literature, we already have descriptions of a Japanese candle using the ordered fuzzy number. In this article, one of these candle models is used as an estimation of an imprecisely determined present value. The applied model description of a Japanese candle has been explicitly defined. In this way, the present value of an individual financial instrument is given as the ordered fuzzy number. The revised definition of the ordered fuzzy number has been used here. The oriented present value of the portfolio is presented as a linear combination of Japanese candles that are components of this portfolio. Thanks to this approach to the financial assets portfolio, the possibility of using of Japanese candles for portfolio analysis is shown.

Opis:
On a daily basis, managers in risk management teams use a number of methods to manage various types of risk. One of the most popular methods of measuring market risk is Value at Risk. Estimation of Value at Risk gives a possibility to determine a loss, which can occur or can be exceeded with a given probability and tolerance level. Moreover, this measure of risk shows in just one number entire risk of the portfolio. In addition, various methods and probability distributions can be used to estimate Value at Risk. A goal of this paper is the evaluation of Value at Risk estimation methods on the basis of backtesting results. In the empirical part, the data for 4 investment portfolios was used. The portfolios were diversified in terms of geographic location of firms that were taken into consideration.

By adopting the perspective of a US equity investor, in this study we empirically verify the diversification benefits resulting from investing in commodities. We make an assessment for specified commodity groups using the commodity sector indices. In the employed methodology we focus only on the risk characteristic of the analyzed portfolios. Our results indicate that the diversification potential of different commodity groups is highly cross-varying, however, at any time greater than the risk-reduction possibilities offered by Emerging Markets equities.

Opis:
The investment attractiveness of capital markets, e.g. the degree of distinction between regional and global markets, determines the ability to adapt to changing environmental conditions and information transparency. Market effectiveness as one of the pillars of the capital market is based on the stability and transparency of the legal framework that determines the possibilities of entering into a transaction. The main research goal of this article is the presentation of the inflow process of portfolio investment in Islamic countries, with a particular focus on the markets of Indonesia and Malaysia, in connection with their investment attractiveness. The strong interest in the capital markets of Islamic countries, especially after the financial crisis of 2008, has led to the dynamic development of these markets as well as the threat of the outflow of the so-called “hot capital”. The causes and effects of these processes are not sufficiently described in the literature.
O atrakcyjności inwestycyjnej rynków kapitałowych, a więc o stopniu wyróżnienia się spomiędzy rynków regionalnych i globalnych, decydują możliwość dopasowywania się do zmieniających się warunków otoczenia oraz przejrzystość informacyjna. Efektywność informacyjna rynku, jako jeden z filarów rynku kapitałowego, opiera się na stabilności i przejrzystości zasad prawnych, które decydują o możliwościach zawierania transakcji. Przedmiotem artykułu jest analiza napływu inwestycji portfelowych w krajach islamskich ze szczególnym uwzględnieniem rynków Indonezji i Malezji. Silne zainteresowanie rynkami kapitałowymi państw islamskich, szczególnie po okresie kryzysu finansowego z 2008 r., powoduje dynamiczny rozwój tych rynków, a także zagrożenie odpływem tzw. gorącego kapitału. Przyczyny i skutki tych procesów nie są jeszcze w literaturze szczegółowo opisane.

Opis:
In this paper the main objective is to examine whether the selection of the performance measure influences the evaluation of individual investments and the performance rankings generated on that basis. This study presents the values of 16 performance indicators along with their detailed descriptions. All calculations were made using the R program, and the source code can be found at the end of the article. Nine selected stock indices were analysed during the period January 1997– December 2015, and the monthly logarithmic rates of return for these indices were calculated. For 14 out of the 16 measures analysed it was shown that the choice of effectiveness measure had no influence on the evaluation of individual investments; therefore it is not important whether the investor uses the Sharpe ratio or the Calmar ratio as an indicator of efficiency since both measures are almost identical in rank for a particular investment. This has not been confirmed for the Upside Potential ratio, which means that using this indicator may lead to different investment decisions in which the objective is to maximize efficiency. Moreover, based on the analysis it was found that the OMXC 20, DAX 30, and OMXS 30 indexes had the highest efficiency during the period January 1997–December 2015, while the AEX, WIG 20, and PSI 20 indexes were characterized with having the lowest levels of efficiency.

The subject of this paper is the forecast of prices and volatility on the Day Ahead Market (DAM). The analysis was made for two portfolios of four contracts from 30.03.2009 to 28.10.2011 for two fixings on DAM. Four out of 24 contracts noted on DAM were chosen by PCA. Prices were forecast by the SARIMA models incorporating autocorrelation and seasonality. Value-at-Risk calculated through the DCC model was used to forecast volatility. These models describe well the prices and volatility on the DAM and may be used for forecasting purposes. Prices on fixing 2 are characterized by higher volatility than prices on fixing 1.

The significance of computerization of the state is permanently increasing. There is extensive evidence for that, like establishment of the Ministry of Administration and Digitalization, creation of Digital Poland Operational Program or designation of more than EUR 3.25 billion in 2014– –2020 for related activities. Information society infrastructure development is planned to be performed on both state- and regional-government levels. This approach enables better identification and meeting of needs but, on the other hand, enforces a need for firm coordination. A dedicated project was appointed to create the system of coordination. The present paper is a summary of results of this project. The results of diagnostic works are presented in the initial sections. The purpose of the diagnosis was to create a solid foundation for the system. The following sections present the system. The presentation of the system is focused on theoretical assumptions for the system and the way of implementing these assumptions in practice. In the conclusion the most important challenges of system implementation were identified and presented.
