The DEA methodology goes beyond conventional efficiency to identify the most efficient mutual funds compared to the rest of the sample. Due to its flexibility including inputs and outputs (without a previously established relationship) and the lack of need for a hypothesis about the production function, the DEA allows for building efficient frontiers using the information collected from each fund. The application of the DEA in the sample of European mutual funds has served to show potential investors its usefulness and effectiveness in terms of fund selection. The results obtained in this study allow the identification of mutual funds with the most significant profitability potential and those with lower expectations of profitability.engjournal articleopen accessAnálisis estadísticoMercado financieroInversiónGoal 8: Promote inclusive and sustainable economic growth, employment and decent work for all
