However in the course of a deeper analysis of the model from the point of view of short-term investment, it can be concluded that the proposed model has a number of features that affect its applicability in the design of optimal portfolios. Results : The author identified the main shortcomings of the Markowitz model, examined the existing ways of their optimization, identified a number of problems that are typical for building micro-portfolios.
