Double-Level Indication of Globalization Effects in Portfolio Investment Models

In well-known reasons, the question of influence of globalization on decisions in the theory of portfolio investment was not discussed, since this was not necessary. The relevance of such a research became actual after the appearance of "young" financial markets only, where the processes of profitability formation of financial assets depended on globalization. In this article, to study this problem, proposed a model that describes a double-level mechanism for profit generating. Usage of this model allowed us to set the specificity of the influence of globalization to the main characteristics of portfolio decisions. Based on this specificity was modified the Sharp's diagonal portfolio investment model with the aim of its practical use in the context of globalization. The performed calculations confirmed the validity of the theoretical recommendations.
