The diversification may be achieved in different ways: an investor may allocate money in different asset classes; or in stocks of different industries; or in bonds with different maturities; or in stocks with large, middle and small market capitalization; or in different commodities and so on. Another way is international (global) diversification. The paper aim is to form an optimal investment portfolio containing assets of different countries.

The proposed algorithm for modeling internationally diversified optimal portfolio includes the following core steps: forming the information base of the research; classification of assets into homogeneous groups and detecting the group that is suitable for the investment; modeling diversified portfolio and a benchmark portfolio; comparison of obtained portfolios performance.Публікація Multi-scale model elaboration for creditworthiness diagnostics of export production enterprises of the agricultural trade market(Scientific Route, Estonia, 2019) Sergienko, Olena; Shapran, Olena; Bilotserkivskyi, Oleksandr; Alieksieieva, IrynaThe methodology for the agrarian enterprises’ creditworthiness diagnostic has been developed and implemented, and has allowed to solve the following objectives: conducting of observations and evaluating of financially-economic indicators, classification of enterprises by the level of creditworthiness, distinction and identification enterprises according to the level of creditworthiness and assessing the differences between classes by creditworthiness, with taking into account the sizes of enterprises.

I.; Shapran, OlenaПублікація Integrated tool development for managing a marketing activity of a trading enterprise in a competitive market(НВП ПП "Технологічний Центр", 2019) Shapran, Evgeniy; Sergienko, O.; Gaponenko, Olga; Shapran, OlenaThe object of research is a comprehensive approach to the formation of the marketing policy of a trading company to improve the effectiveness of marketing activities in the competitive market. The presented approach consists of three main stages, namely: assessment and analysis of the prospects of marketing activities of the enterprise, assessment and analysis of the internal and external environment, management of the marketing policy of the enterprise. To assess the attractiveness level of the field of activity, the Cobb-Douglas production function is used, on the basis of which a number of characteristics characterizing the economic attractiveness of economic sectors are determined. The highest performance indicators are in the area of trade, construction and financial activities. As part of the study of environmental factors, regional segmentation models are constructed using the cluster analysis method, which allows identifying stable groups of objects with similar characteristics. Segmentation allows to get homogeneous groups of regions of Ukraine on the grounds of: development level, level of investment attractiveness, level of economic activity and the need to update household appliances. The result is a group of regions with high, medium and low levels of development. The methods of analysis of variance are applied to study the differences in the product market by region. To study the internal environment, models of product sales dynamics are implemented and forecasts are made that allow to develop a set of measures to improve the company’s sales policy. To assess and predict the level of sales of goods, time-series decomposition models with the identification of components are used: trend-cyclic, seasonal, and random. The used inventory management model for improving sales policy management is adapted to the trading company based on the use of intermediate planning results, namely: demand rates, costs for ordering and storage, lead time. A hierarchy analysis method based on an expert survey on the formation of promotion policy directions is implemented. The obtained priority measures for the use of marketing budget funds, which should be aimed primarily at the development and implementation of effective marketing measures for: promotion and promotion of sales, advertising, personal sales and public relations.
