This paper examines the relationship between seasonality, idiosyncratic risk and mutual fund returns using multifactor models. We use a large sample containing the return histories of 728 UK mutual funds over a 23-year period to measure fund performance. We present evidence that idiosyncratic...

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...
