Документ Analysis Dynamics of the Market Development of Funds for Investment: on the Example of Major ETF(2023) Serhiienko, Olena; Bril, Mykhailo; Lyashenko, VyacheslavThe sustainable functioning and development of both the economy as whole and individual business entities requires constant investment. Such an investment is possible both with the help of bank lending and on the basis of investment. Each of the approaches has its own advantages and disadvantages. In this paper, we consider investment. Investing comes in various types and forms. One of the types of investment is raising the necessary funds through investment funds. For these purposes, stock market instruments are used. We are considering an ETF fund. We examine the dynamics of the fund's main ETF instruments. For this analysis, we use descriptive statistics and wavelet analysis tools. The paper presents many graphs and charts that allow you to understand the course of the study and evaluate the results.Документ Analysis of the Dynamics of Prices for Shares of Leading IT Companies: IBM, Intel, Apple, Microsoft, Casio Computer Co.(2023) Samorodov, Borys; Zastola, Yevhen; Lyashenko, VyacheslavAnalysis and comparison are research tools that allow you to consider various trends and make the necessary informed decisions. Currently, much attention is paid to IT technologies that contribute to the development of business entities, the introduction of new processes, and the formation of an innovative paradigm. This allows us to talk about the importance of IT companies in the formation of sustainable economic development, relationships between contractors and partners. Most of these companies are listed on the stock market where their securities are located. The display of such an appeal is the dynamics of prices for the relevant shares. The paper considers quotes for shares of leading high-tech companies. To do this, we use standard statistical methods, a quantitative comparison procedure, and wavelet theory. As a result of the analysis, we obtained various dependencies and data estimates, which are presented in the form of stock prices. The findings allow us to understand the dynamics that exist in the IT companies market. We can also develop approaches to the choice of investment strategies when implementing innovative solutions. The article contains many figures and diagrams. This helps to understand the progress of the research.Документ Assessment Dynamics the Development of Financial Markets in the UK and Japan in the Context of COVID-19 Pandemic(2022) Lyashenko, Vyacheslav; Bitner, Irina; Bilotserkivskyi, OleksandrThe negative dynamics of the spread of the COVID-19 pandemic affects all areas of daily and economic activity. At the same time, the degree of such influence is largely determined by the continuity of the movement of various financial flows, the possibility of their rapid renewal in cases of emergency slowdown or interruption of movement. For the analysis of the movement of financial flows, it is important to study the development of financial markets. It is important to carry out such an analysis from the point of view of different segments of the financial market. At the same time, it is also necessary to take into account the general trend in the development of the financial market, the relationship of its individual segments. This can be done based on the analysis of the relevant stock indexes. The paper considers the dynamics of the real values of stock indices, which reflect the dynamics of the development of individual sectors of the financial market. The paper also takes into account the aspects of conducting a comparative analysis, which allows us to identify common patterns. To do this, we consider the values of the UK and Japan stock indices. To conduct a comparative analysis, we use the methodology for constructing wavelet coherence estimates. The paper presents many graphs and charts for specific real data. This allows you to understand the logic of the study and the results obtained.Документ Assessment Relationship Between Components of the World's Leading Stock Indices in Reflection on the World Financial Market Dynamics(2021) Lyashenko, Vyacheslav; Sergienko, Olena; Bilotserkivskyi, OleksandrThe development of the global economy presupposes the stable functioning of all its constituent parts, institutions, and markets. Among such markets of the global economy, a special place is occupied by the financial market, which is able to redistribute financial resources. However, such redistribution must be protected from various risks, unfavorable development of negative situations. To solve such problems, the concept of stock indices is used, which reflects the dynamics of price changes for different groups of securities. Knowing the dynamics of the values of stock indices, one can analyze and predict the development of the financial market as a whole. It is also necessary to take into account the relationship of stock indices and the relationship between the components of various stock indices. Based on this, the paper examines a qualitative assessment of the relationship between the components of the world's leading stock indices in reflecting the dynamics of the world financial market. It is proposed to consider such a qualitative estimate taking into account the wavelet coherence. To this end, the paper proposes a general approach to considering a qualitative assessment of the relationship between the components of the world's leading stock indices. The paper considers real data in the context of various world stock indices, presents research results, and draws general conclusions.Документ Comparative Analysis of the Dynamics of Futures for the Dow Jones, S&P 500 and Nasdaq(2023) Serhiienko, Olena; Novikova, Tetyana; Lyashenko, VyacheslavThe stock market plays an important role in the functioning of individual business entities and the development of the financial market as a whole. To understand such dynamics, an important aspect is to study quotes for futures, indices and stocks. Based on this, the paper examines various aspects of conducting a comparative analysis of data on futures for the Dow Jones, S&P 500 and Nasdaq indices. We consider simple aspects of statistical analysis, as well as the mutual dynamics of such indicators. For these purposes, the methodology for estimating wavelet coherence is used.

This helps to understand the results obtained.Документ Development of the Energy Sector in the Display of Key Exchange Indices(2023) Petrukhnov, O. V.; Negliad, A. V.; Lyashenko, VyacheslavEconomic development makes it necessary to provide a sufficient amount of resources and sources of their receipt. Among such objects, a special place is occupied by those that allow you to receive energy. This type of resource is important for the implementation of all types of activities and the functioning of any types of business entities, households. Obtaining this resource is associated with the use of minerals or the possibility of using renewable sources. In the first case, it is important to know the availability of minerals, which is generally determined by the dynamics of the respective prices. These prices are formed as a result of trading on the stock exchange and are determined by the dynamics of the respective stock indices. We consider various exchange indicators. The dynamics of the relationship of such indices is also considered. The paper presents a series of graphs and charts that allow you to understand the progress of the study. The results obtained make it possible to assess the dynamics of the development of the global energy sector.Документ Dynamics of Changes in Commodity Indices for Commodities: Wheat, Corn, Soybeans, Sugar, Cocoa(2022) Lyashenko, Vyacheslav; Serhiienko, Olena; Bilotserkivskyi, OleksandrCommodity indices determine the weighted price of various groups of goods. At the same time, the dynamics of such indices reflects the dynamics of prices for the corresponding goods. In turn, commodity indices are interconnected with the dynamics of indices, both the securities market and the general world market. An analysis of this relationship helps to understand the dynamics of the functioning and development of individual market segments, the economy as a whole, and various business entities. An important aspect of this analysis is the assessment of relationships, primarily between groups of goods that are placed on the commodity market. Based on this, the paper considers the main aspects of the analysis of the dynamics of commodity indices, presents graphs of commodity indices for individual groups of goods, and considers the main statistical characteristics of such data. To assess the mutual analysis of the dynamics of changes in commodity indices, the wavelet coherence methodology was used. This methodology makes it possible to evaluate the mutual dynamics of commodity indices over different time horizons. We can better understand the dynamics of the relevant relationship, which is important for making investment decisions. Such assessments are also important for making decisions about interaction in different segments of the world market or the stock market. Some results of assessments of such a methodology are presented. The paper presents a lot of factual material, which helps to understand the logic of the study.Документ Dynamics of commodity indices and shares of manufacturing companies as a factor in managing the assortment and inventory of an enterprise(Center for Tech and Media Research, 2024) Pyrohova, Svitlana; Gudymenko, Viacheslav V.; Lyashenko, VyacheslavThe study of the effective functioning of various business entities is one of the key areas in the research of various authors. At the same time, one of the factors in achieving such efficiency is to consider the issue of providing the enterprise with inventory for production. A solution to this issue is proposed based on an analysis of the dynamics of quotations of the corresponding commodity indices and shares of companies producing goods. Such an analysis is carried out based on the study of various data series using descriptive statistics and wavelet ideology. For the study, the methodology of wavelet coherence assessments was used, which allows us to obtain the necessary solutions. The work presents various graphs and diagrams that allow you to understand the progress of the study and the results obtained.Документ Dynamics of the Market for Shares of Medium-Sized Enterprises in the Cluster of US Food Companies with a Minimum Market Capitalization(2023) Bilotserkivskyi, Oleksandr; Kaganovskyy, O. S.; Lyashenko, VyacheslavThe functioning and development of business is closely related to the concept of security. Such security applies both to the direct conduct of certain activities and to the content surrounding the enterprise. Food security is of particular importance in this aspect. This type of security largely determines the economic aspects of the stable activity of various areas in ensuring sustainable interaction between business entities, countries and the population. Therefore, the analysis of the activities of enterprises from the cluster of food companies occupies a special place and is important in making appropriate decisions. Among the various characteristics of the activities of enterprises, attention should be paid to the dynamics of the prices of its shares. This allows you to analyze how the functioning of the business entity itself, and to obtain comparative aspects of such activities in comparison with other companies. In the article, on the example of a number of individual enterprises, a cluster of US food companies is considered. A feature of this consideration is the analysis of the activities of companies with a minimum market capitalization. The work presents a lot of drawings and diagrams. This allows us to understand the course of the study, to consider the activities of medium-sized businesses.Документ Estimating the Relationship Between Inflation and Tax Revenues in Selected European Countries: Austria, Germany, France, United Kingdom and Italy(2023) Pyvavar, Iryna; Sokolova, Natalia; Lyashenko, VyacheslavThe state as a special subject of economic relations is constantly in the sphere of influence of various internal and external factors. Among such attributes of doing business, inflation and tax revenues can be distinguished. These metrics are under constant scrutiny. Since it is these attributes that determine the policy of the state in the field of economic relations, and the state can regulate them through its powers and a number of institutional institutions. Thus, the analysis of the dynamics of inflation and tax revenues is an important element in the development of appropriate public policy. The more important point is the study of the relationship between inflation and tax revenues. To solve this problem, we consider a retrospective change in the values of indicators for selected attributes. We also take into account the regional aspect of such interdependence, which is revealed through the analysis of data for different countries. As a research apparatus, we use various statistical methods. We consider the comparative aspect of the obtained results. The paper presents a lot of empirical material in the form of separate graphs and diagrams. This allows a better understanding of the presented analysis. The results obtained can be used to substantiate the strategy of the state's behavior in the sphere of regulation of economic relations.Документ Model of the Relationship Between ETFs of Individual European Countries: Austria, Belgium, Denmark, Croatia, Hungary(2023) Prokopovych, Svitlana; Sosnov, Ihor; Lyashenko, VyacheslavThe development of the economy is associated with the continuity of the investment process on an ongoing basis. Raising funds is possible through bank lending or through the securities market. We consider investments that are received in the stock market. For these purposes, as a rule, ETF funds are used. This allows you to diversify the source of borrowing and reduce risks. But at the same time, one should pay attention to the markets where such funds operate. Each regional market has its own specifics, factors that determine the characteristics of securities trading. You should also take into account the relationship between such structural units of the overall investment process. For the analysis, we use descriptive statistics that help to understand the current trends for investing in the market. We also use wavelet coherence, which is the basis for modeling relationships. This is necessary in order to assess the impact of different segments of the ETF market. The paper considers such countries as Austria, Belgium, Denmark, Croatia, Hungary. The results obtained allow: to evaluate investment decisions, choosing an effective strategy. Many figures and diagrams are presented in the work to understand the results.Документ Mutual Dynamics of Certain Types of Bitcoin: Data from Wavelet Coherence(International Association of Educators, Scientist, Technologist, and Engineers (IA-ESTE), Indonesia, 2021) Lyashenko, Vyacheslav; Bilotserkivskyi, Oleksandr; Pyvavar, Iryna; Kots, HryhoriiUnconventional methods of analysis are a good tool for studying new trends and phenomena. One of these objects of research is the cryptocurrency market. The paper shows the possibility and feasibility of applying the ideology of wavelets to analyze the dynamics of prices for cryptocurrencies. For this, the methodology of wavelet coherence is used.

Such attention to the foreign exchange market is due to the fact that it provides stable economic and organizational relationships in the implementation of transactions for the purchase or sale of foreign currency. This, in turn, has a significant impact on the development of international economic relations. Thus, the analysis of the foreign exchange market plays an important role in the evaluation of various economic processes. To analyze the situation in the foreign exchange market, it is necessary to have primary data. As a source of primary data for the foreign exchange market are empirical data on the dynamics of the exchange rate. At the same time, it is necessary to know the dynamics of the exchange rate from the point of view of different countries. This increases the reliability of the results that can be obtained from the corresponding analysis. We can also evaluate the mutual influence on the dynamics of exchange rates from the point of view of individual countries. For such an analysis, we use the ideology of wavelets. This ideology allows the analysis of data presented as a time series. Among the methods of wavelet ideology, we consider wavelet coherence. This approach allows us to evaluate the mutual dynamics of exchange rates for different countries. The paper presents the results for real data. The paper presents many graphs and diagrams that allow you to better understand the progress of our study, interpret the results.Документ On the Ratio of Futures Prices in the World Markets for Grain Commodities(2023) Bilotserkivskyi, Oleksandr; Stepurina, Svitlana; Lyashenko, VyacheslavGrain products play an important role as a factor in stable economic development. These goods provide food security, security of life support and activities of people. At the same time, the market for grain products is subject to the influence of various destabilizing factors, which affects the price of such products. Generalization of prices for any goods is the price dynamics for the corresponding futures goods. Thus, in order to analyze changes in the market of grain products, it is advisable to study the dynamics of prices for futures for these products. This allows you to understand the dynamics of the formation of a parity price between supply and demand. Such dynamics is formed under the influence of market factors, the impact of destabilizing factors, the conditions for the development of the relevant market segment and the actions of investors. For the corresponding analysis, we use descriptive statistics, which allows us to analyze current trends, identify peaks in changing price dynamics. To conduct a comparative analysis of price dynamics for various grain products, we use the wavelet ideology. Such an ideology makes it possible to obtain wavelet coherence estimates. These estimates contribute to the study of the grain market, the consideration of various investment strategies. The paper presents various graphs and schemes that allow you to repeat experiments and evaluate the results.Документ Price Environment for Gold and Silver in the Context of the Development of COVID-19(2020) Baranova, Valeria; Sergienko, Olena; Stepurina, Svitlana; Lyashenko, VyacheslavThe precious metals market is an integral part of the overall financial market. This part of the financial market plays an important role in the redistribution of financial flows. The precious metals market is currently under the influence of factors related to the spread of the COVID-19 pandemic. We investigated the dynamics of gold and silver prices in the context of the current pandemic development. For this analysis, we use the wavelet ideology. The results can be used in exchange trading in precious metals, investing in gold and silver.Документ Wavelet Analysis Methodology as a Tool for Predicting Cryptocurrency Price Dynamics(2021) Lyashenko, Vyacheslav; Sergienko, O. A.; Stepurina, S. O.The stock market allows you to attract free investment resources, redistribute free financial resources between various spheres of the economy, business entities. For this, various tools and mechanisms for raising funds are used. Cryptocurrency is one of the tools of the modern stock market. The attractiveness of cryptocurrency, sharp and rapid changes in cryptocurrency prices necessitate various studies. At the same time, it is important to consider not only the dynamics of prices for cryptocurrencies, but also the mutual dynamics of prices between different types of cryptocurrencies. This is important in the aspect when choosing and building various forecasting models, assessing the mutual dynamics of cryptocurrency prices. To solve such a problem, it is necessary to carry out a complex and comprehensive analysis of the data. At the same time, it is important to obtain additional information that will be useful in the corresponding analysis. For this, it is proposed to use the wavelet ideology. We consider wavelet coherence as a data analysis tool. This choice is justified, and also the feasibility of its use on various datasets is confirmed. The paper deals with the mutual dynamics of prices for various types of cryptocurrencies. For this purpose, the corresponding estimates of the wavelet coherence are considered in the work. These estimates are based on real data. These estimates allow a number of conclusions to be drawn about cryptocurrency price prediction. In the work, information is presented in the form of various graphs and diagrams. This allows us to repeat and check the obtained estimates of the wavelet coherence, to evaluate the results that have been obtained.
