Investment Portfolio Risk Assessment on the Basis of Hierarchical Model
Introduction. Efficiency of investments is an important factor at the micro- and macroanalysis of economy, investment in venture capital depends on the development of firms, regions, States. Especially actual this problem for portfolio investment. The aim of this work is to develop a new minimax method for modeling the dynamics of risk of portfolio investment, which allows to assess the distribution of equity is a structural component of a financial portfolio. Methods. Suggested new method for modeling and rationalizing the structure of equity investments using the minimax criterion. Drill through the decision of the investor as from the original portfolio preferences, specific risk assessments for each lower level in the hierarchy (topdown) and a calculation of expediency of inclusion in the portfolio of each asset of the lower level, with specific risk assessments (bottomup), which is consistent with the approaches of fundamental analysis of securities market. Provided step-by-step algorithm for grouping, clustering and data analysis along the branches of the hierarchy. Results. Is developed the scheme the implementation of the model for a three-tier structure for complete binary decision tree. Is given the iterative computational algorithm and its implementation. Conclusion. The recommendations can be applied to rationalize the funding of innovations that improve the quality of development of regions in the rehabilitation plan for selected executives of corporate sector.
