This paper deals with problems of modern theories of portfolio as a follow up of establishing the complex relationship of risk in the previous chapter and establishes that the analysis of the risk of a portfolio can only be made in close connection with the prognosis of profitability. Although the studying of these phenomena has been realised scientifically ever since the beginning of the 20th century, there can be established as components of the modern theory of portfolio a series of models of analysis and estimating of the relationship central to the management of the portfolio, namely the correlation profitability – risk.
