Abstract
In the last years the interests of the pension funds have considerably gone down and sometimes it has been negative (in real terms). Due to the obligation of each worker to use a pension fund company, this research will analyze the combination of interest/risk to the affiliated workers. Although the results of this research shows, in general terms, that the relation between interest/risk is not different from the theory, but in fact necessary to implement multi-funds, allows the affiliates to choose their profile of interest/risk.By submitting a contribution to consideration of the Editorial Board of Fórum Empresarial, the authors attest that it is an original, unpublished work, which has not been nor will be simultaneously submitted to another journal for consideration and publication; that they are responsible for the work carried out and the content of the article; and they have the corresponding copyrights.
