Knowledge about risk and efficiency is important for all stock market participants, i.e. customers, investors, and business entities. It provides the necessary information helpful in making decisions about assets in which we may invest capital to generate the highest possible profit with minimal risk. The most common measures used by managers are the so-called classic measures of risk and efficiency, however, correct inference based on them requires meeting the assumption of normality (log normality) of the distribution of rates of return. Therefore, the work first examined the distribution of rates of return of selected IF with a diversified investment strategy, and then verified the impact of departing from the normality of the distribution on the justification for using alternative measures. In addition, the article verifies the thesis whether the ranking positions of the funds depend on the adopted performance indicators. As a consequence, it turned out that the rankings created on the basis of the used classic and alternative indicators based on semi-bias lead to similar conclusions on effectiveness as opposed to the so-called measures examining the relation of profits to losses.
