In this paper we evaluate the performance of nine mutual funds in the Republic of Serbia in the period 2011-2013 by integrating traditional approaches for measuring absolute efficiency and the selected multi-criteria decision-making methods for measuring relative efficiency. The aim of our research is to test selection abilities of Serbian portfolio managers. Performance evaluation of mutual funds, being by its nature a complex problem of multi-criteria decision-making, must be solved by the methods that have, at least, the same level of complexity. Research results indicate that mutual funds have inferior performance, which on the other hand, confirms that the national portfolio managers lack selection abilities.
