Equity mutual fund managers performance in Greece

Outlines the models devised by Jensen (1968, 1969) and Treynor and Mazuy (1966) for measuring the performance of managed portfolios and related empirical research. Applies the Treynor‐Mazuy model to a sample of 17 Greek equity mutual funds using 1995‐1998 daily returns data and presents the results, which show no evidence that fund managers can select the right market timing or (except for four) undervalued securities.
