W porównywaniu akcji notowanych na giełdzie stosuje się najczęściej kryteria wykorzystujące wybrane parametry rozkładu, wyznaczane na podstawie danych historycznych przy założeniu dyskretnego rozkładu losowych stóp zwrotu. Miarą uwzględniającą pełną informację o rozkładzie jest wskaźnik omega. W artykule przedstawiono przykład zastosowania wskaźnika omega do oceny akcji przy założeniu ciągłego rozkładu stóp zwrotu. Celem pracy jest empiryczna weryfikacja zależności uporządkowania (względem wskaźnika omega) losowych wariantów decyzyjnych od przyjętego rozkładu.

When comparing shares quoted on the stock exchange, investors the most often use the criteria which are based on selected parameters of the probability distribution. In such approach historical date are being used and a discrete probability distribution of random returns is assumed. The omega ratio is a measure which takes into account all the information about the probability distribution. In this paper we present the example of applying the omega ratio to the evaluation of shares assuming a continuous distribution of returns. The aim of this paper is to empirically verify the relationship between the order (according to the omega ratio) of random decision alternatives and the assumed probability distribution.

This paper presents the Omega meter - quite new tool to measure investment efficiency and risk. One of its major advantages is the independence from the assumptions made regarding the distribution of investment returns being analysed. It also allows for comparison of investment efficiency and riskiness of different assets. The article focuses on the essential characteristics of the meter and the presents methods for its point estimation. An empirical comparison with other risk adjusted measures of investment efficiency was made. The comparison was performed on investment funds of different categories. Omega meter in some cases allows to obtain more valuable information than the other regarded measures of investment efficiency. However, empirical research shows that efficiency measurement results are not much different when using Omega and Sortino ratio.

It argues the growing influence of the European Union on the construction of national state aid systems, which now goes beyond ensuring compliance with competition rules in the single European market.
