This paper examines the relation between idiosyncratic risk and mutual fund performance using asset pricing models. We use a unique data set containing monthly returns of 949 UK equity mutual funds over a 28-year period to measure fund performance. We find that idiosyncratic risk cannot be...

This paper challenges existing studies of mutual fund market timing that find little evidence of timing ability. Using a sample of daily returns for 35 countries, we find that more than a third of mutual funds show significantly positive market timing ability across all countries. We show that...

This paper analyzes the short-term market efficiency of the mutual fund industry around the world. Using a unique database of worldwide domestic equity funds, it employs a parametric (regression model) and non-parametric (Data Envelopment Analysis (DEA) model) approaches to establish a relation...
