In this paper we propose some models for the evaluation of the performance of mutual funds within a DEA approach that are able to tackle the problem of the presence of negative average rates of returns. The three models presented adjust some models previously proposed in the literature and regard a model that can be used for investments in mutual funds which have profitability as main objective...
