Сравнительный анализ критериев выбора инвестиционного портфеля на фондовом рынке с несимметричным распределением доходностей акций
Internal rate of return IRR is one of the key criteria for justifying and choosing capital investments with conventional cash flows. However, this criterion is not practically used when the rate of return of investment instruments (short sales, options, futures, swaps) is calculated because these instruments create non-conventional cash flows. The author previously showed that IRR problems were observed when the present value of cash flows changed sign from period to period. This paper offers a criterion to evaluate the rate of return of investment instruments with non-conventional cash flows, i.e. General Rate of Return (GRR).
One of the fundamental concepts of financial theory is to find compromise between risk and return. In the traditional approach to ratio of risk and return - higher yield faces a higher risk. It does not take into consideration the timeframe of investments. Purpose of this article is to analyze the risk-profitability ratio of financial instruments depending on the investment period in developed and emerging markets. The analysis showed that the prolongation of the investment period reduces the risk indicators, and the yield remains almost constant. At long time periods shares indicate higher returns with lower risk.
