Abstract
In this work we make a traditional portfolio analysis using the Sharpe ratio to identify the market portfolio. This measure of investment performance was compared with those obtained with bootstrapping the Sharpe ratio. The results indicate that the choice of market portfolio is greatly affected by the uncertainty regarding the estimation of expected returns and the variance-covariance matrix of returns, i.e. the estimation risk associated with these parameters.Análisis de portafolio; bootstraping
