Публікація Model for Predictive Analysis of International Trade Based on the Dynamics of Stock Indices (Example of Data from the USA, Canada and UK)(2022) Rudenko, Diana; Serhiienko, Olena; Zeleniy, Oleksandr; Lyashenko, VyacheslavForecasting is one of the tools for assessing the functioning and development of processes, phenomena, objects. This tool has found its application in all areas of research. Among these areas of research, one should single out the direction that is associated with the economy. This is important because such studies help to assess the level of economic development, the welfare of mankind, to find ways for the further functioning and development of various processes, phenomena, objects. To solve the tasks set, various models are used that help to implement a certain forecast scheme. At the same time, the construction of such models involves the implementation of the corresponding stages of modeling. Such modeling steps help determine the type of the final model and implement the required predictive model. Therefore, we pay special attention to the individual stages of predictive modeling. The efficiency of building a predictive model is also determined by the applied problem that needs to be solved in the modeling process. In this paper, we consider the elements of a predictive model for the analysis of international trade. To do this, we use data on the dynamics of stock indices. In particular, we use the dynamics of stock indices, which describe the activities of banking institutions. To build individual elements of the predictive model, we use the apparatus of wavelet theory. Among the tools of wavelet theory, we use wavelet coherence. We also propose an approach for comparing different estimates of wavelet coherence. This approach is based on comparing the corresponding wavelet coherence estimates and visualizing the results. This allows you to better understand the mutual dynamics of stock indices and evaluate the dynamics of international trade. The paper presents various graphs and diagrams that help to understand the logic of the study and the results obtained.Публікація Comparative analysis of the stock market for trading goods of companies in different sectors as a factor in the development of retail and product promotion(Center for Tech and Media Research, 2024) Kyzliuk, Oleksandr; Momotkov, Ihor; Mehyar, SamerRetail occupies special attention in the process of formation and development of economic relationships between various business entities. For these purposes, it is advisable to study the dynamics of shares of individual trading companies in the context of various sectors of the economy.

The work presents a variety of graphs and diagrams that allow you to understand the progress of the study and evaluate the results obtained.Публікація Dynamics of the relationship between the main stock indices in the context of changes in external factors(Center for Tech and Media Research, 2024-03) Sosnov, Ihor; Savchenko, Roman; Mehyar, SamerEconomic development presupposes the sustainable functioning of all structural elements, among which due attention is given to the stock market. This market allows us to understand the dynamics of the supply/demand relationship, redistribute resources between various business entities, and act as a platform for investment. To implement such tasks, an analysis of the dynamics of quotes for the corresponding shares or their group, which make up various stock indices, is used. Based on this, the work analyzed the dynamics of quotes for the main stock indices. For these purposes, the features of each of the considered indices are considered separately. The paper also provides an assessment of the mutual dynamics for some pairs of major stock indices. This analysis is made on the basis of constructing estimates of wavelet coherence. This approach allows us to justify possible investment strategies and the timing of entry into the corresponding segment of the stock market. The results of the study are presented in the form of graphs and diagrams. This helps to understand the progress of the study and evaluate the results obtained.Публікація Energy market dynamics as reflected in selected european global indices(2024) Bril, Mykhailo; Petrukhnov, Oleksiy; Mehyar, SamerThe energy market plays an important role in providing appropriate resources, both for the needs of each person and for the development of various economic agents. Such provision makes it possible for individual business entities to function normally, to develop the economy and to satisfy the basic needs of people. Energy resources include oil, gas, fuel oil, and coal. The sale of these resources is carried out through their free sale on the market using various instruments in the form of certain securities. For the purposes of energy market analysis, it is important to know the quotes of such securities, taking into account the peculiarities of the functioning of a certain market segment. Based on this, the work examines the dynamics of the energy market as reflected by individual European global indices. The article presents the dynamics of individual indicators of the corresponding indices and conducts their comparative analysis. This allows you to determine the best time to enter the market. The work presents various graphs and diagrams that allow you to understand the progress of the study and evaluate the results obtained.Публікація 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.Публікація 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.Публікація Analysis of the dynamics of Europe stock markets development(Fintechalliance LLC, 2023) Serhiienko, Olena; Bril, Mykhailo; Baranova, Valeria; Tatar, Maryna; Bilotserkivskyi, OleksandrThe article proposes a complex of economic and mathematical models of assessment, analysis, and forecasting of the world stock indices development state for effective management of investment flows. The modern concept and strategy of European countries’ stock market development were considered, and the existing methods of diagnosing the stock market development level were analyzed.

The possible trends in the stock indices development for the future period were analyzed using predictive models. It makes it possible to determine directions for improving the stock market efficiency and investment strategies in modern conditions.The proposed set of models for evaluation, analysis, and forecasting of the world stock indices state can be used to test various trading strategies and to test various hypotheses in relation to the entire stock portfolio of a particular company or to one stock index. The results of the research can be used in the development of theoretical provisions and methodological tools for evaluating the global stock market effectiveness in modern conditions and development trends in local markets.Публікація 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.Публікація 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.Публікація 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.
