Abstract

In today's world, the stock market is an essential component of the global economy, and successful investment management requires consideration of many factors such as profitability, risks, and uncertainty. This article discusses the methods of mathematical modeling of the dynamics of an investment portfolio in order to make optimal decisions in the face of uncertainty and risks in the stock market. To build a mathematical model of portfolio dynamics, the stochastic optimization method was used, which allows taking into account the variability of asset returns and their interrelationship. The model uses stochastic differential equations to describe the movement of market prices of assets, taking into account risks. The study also uses utility functions to analyze the preferences of investors seeking to maximize returns with minimal risks. An important aspect is to consider the uncertainty associated with future market changes, which is modeled using various scenario approaches. The simulation results show that when using the proposed stochastic model, the portfolio can be optimized more efficiently than with classical approaches such as mean-variance analysis (Markowitz model). The developed model makes it possible to reduce the negative impact of market fluctuations on the total portfolio income, which is especially important in a highly volatile market. In addition, taking into account uncertainty greatly increases the sustainability of investment decisions. Mathematical modeling using stochastic methods allows you to create optimal portfolio management strategies that take into account risks and uncertainties. The results obtained can be used by both private investors and institutional participants in the financial market for more accurate forecasting and asset management in conditions of instability and uncertainty. This helps to reduce risks and increase the profitability of portfolios on the stock market.
