On some approaches to evaluating the effectiveness of investment projects

In the modern world, investment activities are carried out by many companies and are considered a factor that ensures the development of the company, its liquidity and financial stability. Thus, project management and the development of methods for their evaluation is a relevant and important problem of the modern economy. The purpose of this study was to study the system of models for evaluating the investment activity of the company. Traditional valuation methods do not take into account flexibility in management and competitive advantages in the calculation, and therefore the paper considers both the classical Black-Scholes model and the theory of real options. This article presents the essence, advantages and disadvantages of each of the methods, which helps to explore and work on new ways to evaluate options, since there is no such method that could give an unambiguous guide to management decisions.
