An analysis of Spanish investment fund performance: some considerations concerning Sharpe's ratio

摘要

This paper concentrates on the financial analysis of investment performance taking Sharpe's ratio as a basic point of reference, as well as giving further consideration to the use of this performance measure as an approximation to a utility index. We also propose certain changes to Sharpe's ratio which would, on the one hand, avoid the appearance of inconsistent assessments and, on the other, provide an approach to the use of Sharpe's performance measure as a utility index. All of the measures involved in this study have been applied to a sample of Spanish investment funds.
