Opis:
The article is classifying and presenting the art market indexes, thus supplementing the knowledge about indexes and considering different measuring methods of return of investment on this market. It is also organising the knowledge about methods of measurement, such as indexes, which can be regarded as benchmarks. Due to the universal usage of indexes the benefits could be used both by individual and institutional investors, as well as the art collectors or analysts. Thanks to the provided ranking and indexes, conclusions on the advantages and disadvantages of each benchmark are presented and so are questions constituting the basis for future empirical research. Indexes are determined as one of the key measurement tools for testing investments, risks, volume of trade and market trends on the new, but still little known art market in Poland.

Opis:
It is common opinion among the financial media and a wide range of investors in Poland that the NewConnect (NC) market is not an attractive place for investments. The NC market is dominated by penny companies with low liquidity of shares that encounter significant problems with fulfilling information obligations. This paper disputes this view by referring to companies from the NewConnect market. The authors aim at identifying new solutions, to improve the perception of the NewConnect market among all groups of its participants. These include the construction of new NC indicators: i) an indicator designed to measure the development level of companies from the NC Focus segment (NCGI-Focus) and ii) an indicator measuring the degree of changes in the market value of issuers from the same segment (NCFocusValue). This is supplemented by empirical results.
Wśród mediów finansowych oraz szerokiego grona inwestorów można się spotkać ze stwierdzeniem, że rynek NewConnect (NC) nie jest atrakcyjnym miejscem do dokonywania inwestycji, że na NC dominują spółki groszowe o niskiej płynności akcji, że indeks obrazujący zachowanie kursów akcji emitentów notowanych na tym rynku znajduje się w wieloletnim trendzie spadkowym. W niniejszym artykule podjęta została próba polemiki z powyższym poglądem, a autorzy postawili sobie za cel wskazanie nowych rozwiązań, których wprowadzenie mogłoby w istotnym stopniu poprawić odbiór rynku NewConnect wśród wszystkich grup uczestników tego rynku. Rozwiązania te to wskaźnik mający za zadanie dokonywanie pomiaru stopnia rozwoju spółek z segmentu NC Focus (NCGI-Focus) oraz wskaźnik mierzący stopień zmian wartości rynkowej emitentów z tego samego segmentu (NCFocusValue). Autorzy referatu przedstawili nie tylko zarys metodologiczny, lecz także poparli zasadność wprowadzenia obu miar wynikami empirycznymi odnoszącymi się do okresu funkcjonowania segmentu NC Focus.

Opis:
The main objective of the paper was to study connections between the financial markets including the Polish stock exchange market. The author wanted to respond to the following questions: • How strong are correlations among the main stock exchanges in the world? • What is the time (bear market or bull market) with stronger interdependencies among global financial markets? • What markets are most related to Polish WIG 20 Index? The author gathered data from 1999 till 2011. Correlation is calculated for the main global stock exchanges but it also contains Polish market. We can see that the longer period of calculation the weaker connections among stocks all over the world. Furthermore in crisis time interdependencies are stronger what leads us to support a hypothesis that diversification among stock markets does not work properly because of global economy. Next research in this area should focus on the fundamental determinants of international correlation across equity markets. Studies have to take into consideration industry specifications of each national market as well as the correlation of the countries’ business cycles.

Subject and purpose of work: This paper explores whether herding behavior is formed according to the type of investor, how long the transmission of herding behavior occurs, and identifies how big the reaction of herding behavior is and how the flow of herding behavior connects between investors. Materials and methods: The population in this study are companies whose shares are listed in the LQ45 index list for the period January 2015 to December 2017 on the Indonesia Stock Exchange. To find out further about herding behavior, a VAR test will be conducted in this study. Results: The results of herding behavior analysis, based on the type of investor on the Indonesia Stock Exchange, show that there is herding behavior in each type of similar investor. Moreover, there is a certain period for the spread of herding behavior by type of shareholder. Conclusions: The most influential variables on the four types of successive investors are domestic institutional investors, individual foreigners, domestic individuals, and foreign institutions. The four types of investors respond differently to herding behavior.

Opis:
The profitability of analysts’ recommendations is documented in numerous studies from all over the world. However, the evidence from the Polish market is relatively modest. The primary aim of this study is to fill this gap. The paper contributes to the economic literature in four ways. First, it provides fresh out-of-sample evidence on return patterns following analysts’ recommendations from Poland. Second, it examines the relations between these patterns and the size of the rated companies. Finally, it investigates whether it is possible to design profitable strategies based on the discovered patterns. We use monthly stock level data from Poland and the sample period is 2004-2013. In order to examine the profitability of analysts’ reports, we build market-neutral portfolios and test their performance against CAPM, Fama-French three-factor and Carhart fourfactor models. The principal findings can be summarized as follows. First, we document that the top rated companies deliver better returns than the bottom rated companies. Second, we find that the profitability is particularly impressive among the small companies. Third, the abnormal returns are partially explained by momentum and value based factors. Finally, we provide evidence that strategies based on information in recommendations deliver statistically significant positive abnormal rates of return.

Financial market participants are influenced by the news reaching them from all manner of sources, including the country’s central bank. In this paper we model daily returns of WIG20 index with respect to announcements made by the National Bank of Poland (NBP) regarding the changes of the official interest rate of open market operations (the so-called reference rate) during the period of 2004-2016. The goal is to examine whether the NBP’s announcements have an impact on either stock returns or volatility and whether the content of such communiqué (either interest rate cut or raise) matters. The FIGARCH model is found to be an appropriate specification for the data. Moreover, the results suggest that, in fact, interest rate changes do have a significant impact on both returns and volatility. However, the reactions to news are different with respect to the type of announcement.

Opis:
A number of studies assert that during critical events cross-market correlations change substantially. The main focus of this paper is to explicitly test two research hypotheses concerning the effect of increasing cross-market correlations in the 2007-2009 Global Financial Crisis (GFC) compared to the pre-crisis period. These hypotheses state that there was no contagion and no integration effects among the U.S., the U.K., and selected African stock markets (South Africa, Namibia, Egypt, Nigeria, Morocco and Kenya) during the GFC. The crisis periods are formally detected using a statistical method of dividing market states into bullish and bearish markets. The sample period begins in January 2003 and ends in December 2013, and it includes the 2007 U.S. subprime crisis. Obtained results indicate that there is no reason to reject both research hypotheses. Moreover, the results confirm a heterogeneity of the African equity markets in the context of the influence of the recent global crisis.

Opis:
The paper examines relationships between selected stock market indices in Western Europe, Central Europe, and the United States. The study focuses on two periods, from January 1998 to August 2006 and from September 2006 to December 2016. The first one includes stock quotes from before the financial crisis while the second one covers the crisis and changes in the economic situation in post-crisis years. Relationships between stock market indices in developed economies were more frequent and durable than in Central Europe, although they were subject to changes. In our investigation into Granger causality relationships we observed changes in these relationships and in their direction for stock markets in Central Europe, while bidirectional relationships between indices in developed economies remained stable over time. Changes in relationships between indices, in particular long- -term interdependences, may result from the impact of the 2008 financial crisis. The increased number of causality relationships for the markets in Central Europe may testify to the advancing integration of the EU common market.

Opis:
This paper investigates the properties of South African stock returns and the underlying variance. The investigation into the properties of stock returns and the behaviour of the variance underlying returns is undertaken using model-free approaches and through the application of ARCH/GARCH models. The results indicate that, as with other stock markets, returns on the South African stock market depart from normality and that variance displays evidence of heteroscedasticity, long memory, persistence, and asymmetry. Applying the EGARCH(p,q,m) and IGARCH(p,q) specifications confirms these findings and the application of these models suggests differing characteristics for variance structures underlying the South African stock market. In light of the findings relating to the properties of stock returns and the characteristics of variance and its structure, implications are outlined, and recommendations on how time-series specifications may be estimated are made.

Opis:
In this paper we investigate the characteristics of the low price anomaly, which implies higher returns to stocks with a low nominal price. The research aims to broaden academic knowledge in a few ways. Firstly, we deliver some fresh evidence on the low price effect from the Polish market. Secondly, we analyze the interdependence between the low price effect and other return factors: value, size and liquidity. Thirdly, we investigate whether the low price effect is present after accounting for liquidity. Fourthly, we check to see whether the low price effect is robust to transaction costs. The paper is composed of three main sections. In the beginning, we review the existing literature. Next, we present the data sources and research methods employed. Finally, we discuss our research findings. Our computations are based on all the stocks listed on the Warsaw Stock Exchange (WSE) in the years 2003-2013. We have concluded that the low price effect is present on the Polish market, although the statistical significance is very weak and it disappears entirely after accounting for transaction costs and liquidity.

The aim of the article is to analyse the change in the quotations of Polish listed companies, which change the stock exchange index as part of the periodic change in the composition of the WIG20, mWIG40 and sWIG80 stock market indices. The research methodology uses abnormal return (AR) based on daily logarithmic rates of return of Polish listed companies and daily logarithmic rates of return on the stock market indices (WIG20, mWIG40, sWIG80). In this way, they defined the relative strength of listed shares in relation to the stock indices revision a month before the composition of the stock index, when the drawn up list of companies is changing the composition of the index. In addition, the relative strength of quoted shares in relation to stock exchange indices after the revision of the composition of the stock exchange index in the short-term (one month) and medium-term perspective (six months) was examined. The research was based on quarterly changes in the composition of stock exchange indices in the years 2010-2015. The analyses carried out indicate the existence of positive surplus stock returns a month before the change in the stock index. The average number of quotes of these companies above the stock market index at the time amounted to +0.52 percentage points. In turn, the average increase in the prices of the debuting companies in the new stock exchange index within 6 months after their flotation it amounted to +0.97 percentage points over the benchmark (WIG20, mWIG40, sWIG80).

Opis:
Over the past forty years, stock exchanges have undergone a number of transformations (legal, organizational and technological). They resulted both from general external conditions (including technological progress) as well as were the expression of various economic (structural) policies. Two of which seem to be basic. The first implemented in France, based on optimal centralization of stock exchange trading. The second one, implemented in Germany and Spain, expressing the concept of a complementary and effective combination of the potentials of the main trading floor and regional exchanges. Promisingly, especially in this latter dimension of experience together with the Edinburgh ‘stock market experiment’ that has just begun, they may reveal yet another not yet fully recognized characteristic of the stock market - the institutional exemplification of the market economy.

In the paper common long-term dynamics of return volatility and trading volume of the largest companies listed on Warsaw Stock Exchange in 2005-2011 is examined. The existence of contemporaneous relationship between volatility and volume is implied by the Mixture Distribution Hypothesis which states that volatility and trading volume are jointly generated by information flow process. In the study realized volatility computed on the basis of high frequency data is used as a measure of return volatility. It is more efficient measure of daily return volatility than commonly used absolute or squared returns.

measure of herd behavior
Opis:
According to literature, herding can be observed not only within single stock market, but also on international level. Poland has entrance to Euro Zone in perspective, so especially interesting is answer to the question whether herding is present on the stock markets of candidate countries to Euro Zone? Moreover, whether this tendency will be more noticeable in periods of higher volatility than during the periods of relative market stability, as suggested by psychological theories. To find the measure of herd tendency we can refer both to neoclassical and behavioral theories. Basing on models grounded in rationality assumption, there is a need to assume informative efficiency of markets. Thus, it can be expected that aggregated changes in stock markets should be reflected in the process of prices formation. Behavioral literature pointed that if tendency of herding is present on international level, it can be assumed that markets ‘in average’ will behave in the similar way. Following this idea the size of deviation of the given series from the ‘average’ can be taken as the measure of herding activity in aggregated market. Methodology created by Christie, Huang and Chang, Cheng, Khoran will be used as a starting point for the consideration of this problem. To propose more perfect measure of herding, in the paper this approach will be developed by using alternative methodology for average and measure of deviations construction. Those improvements will cause that, theoretical models will come closer to reality and will take into account both sociological and behavioral tendencies present in investors activity.

Opis:
In this paper we proved that a fast fixed point algorithm known as FastICA algorithm depending on maximization the nongaussianity by using the ne-gentropy approach is one of the best algorithm for solving ICA model. We compare this algorithm with Gradient algorithm. The Abu Dhabi Islamic Bank (ADIB) used as illustrative example to evaluate the performance of these two algorithms. Experimental results show that the FastICA algorithm is more robust and faster than Gradient algorithm in stock market analysis.

Opis:
Advancing globalization provides access to more information. It also affects the frequency of data. Some events are listed on a monthly, daily and even minute basis. Thus, during the time-space study selecting appropriate and relevant information becomes a problem. The paper presents a suggested solution to this problem based on the example of stock exchanges in Central and Eastern Europe.

Opis:
This study examines the mediating role of volatility on the relationship between analyst recommendations and herding in the Malaysian stock market by using data from 2010 to 2020. Volatility is measured by realized volatility and the Parkinson estimator. The empirical evidence suggests that herding exists and realized volatility intervenes in the direct relationship between analyst recommendations and herding. The release of analyst recommendations causes realized volatility to fluctuate and investors are triggered by the volatility, which in turn follow the crowd to herd. Nonetheless, the Parkinson estimator is found to be insignificant, which infers that investors have anchor bias and rely on previous day stock prices to trade and herd. This paper provides an alternative explanation to the direct relationship and enhances the study of informationbased herding. It contributes to academicians, practitioners, investors and policymakers to understand the herding of investors in responding to the arrival of new information.

Opis:
The influence of the spatial relation on the stock market is becoming more frequently the subject of a discussion. Efforts to pinpoint the relation between the dis- tance and the investors choices are relevant to both the intra- and intermarket connec- tions. With the latter one, spatial dependencies may function as a shock transmission channel, resulting with the contagion effect. The object of this paper is to present the results of the research on the influence of spatial and economic distance on the correlation of selected European stock markets during the 2007–2009 crisis period. In order to verify the hypothesis regarding the influ- ence of the spatial relations on the stock market correlation DCC GARCH model was used among with spatial analysis tools.

Opis:
Research background: Research and measurement of sentiments, and the integration of methods for sentiment analysis in forecasting models or trading strategies for financial markets are gaining increasing attention at present. The theories that claim it is difficult to predict the individual investor's decision also claim that individual investors cause market instability due to their irrationality. The existing instability increases the need for scientific research.   Purpose of the article: This paper is dedicated to establishing a link between the individual investors' behavior, which is expressed as sentiments, and the market dynamic, and is evaluated in the stock market. This article hypothesizes that the dynamics in the market is unequivocally related to the individual investor's sentiments, and that this relationship occurs when the sentiments are expressed strongly and are unlimited. Methods: The research was carried out invoking the method of Evolino RNN-based prediction model. The data for the research from AAII (American Association of Individual Investors), an investor sentiment survey, were used. Stock indices and sentiments are forecasted separately before being combined as a single composition of distributions. Findings & Value added: The novelty of this paper is the prediction of sentiments of individual investors using an Evolino RNN-based prediction model. The results of this paper should be seen not only as the prediction of the connection and composition of investors' sentiments and stock indices, but also as the research of the dynamic of individual investors' sentiments and indices.
