Resumen de Disposition effect and mutual fund performance

M. Ammann, Alexander Ising, S. Kessler

• This article finds strong evidence for the presence of the disposition effect among US mutual fund managers. The analysis can establish a link between the disposition effect and mutual fund characteristics as well as changes in the macroeconomic environment. Managers with a lower disposition effect are found to invest in larger equities with a higher trade volume, a higher past performance, lower idiosyncratic risk, and a higher risk-adjusted performance. However, fund characteristics and the economic environment can only explain a limited amount of the variation in the disposition effect across mutual funds. Using a new methodology to reduce the disposition effect exhibited by mutual fund investments, we find no increase in their profitability. Although statistically significant, the disposition effect has only a minor economic effect on fund performance.
