Mutual Fund Performance: Evidence from the UK

This paper uses a large sample containing the complete return histories of 2300 UK open-ended mutual funds over a 23-year period to measure fund performance. We find some evidence of underperformance on a risk-adjusted basis by the average fund manager, persistence of performance and the existence of a substantial survivor bias. Similar findings have been reported for US equity mutual funds. New findings not previously documented for other markets include evidence that mutual fund performance varies substantially across different asset categories, especially foreign asset categories. We also identify some new patterns in performance related to the funds' distance from their inception and termination dates: underperformance intensifies as the fund termination date approaches, while, in contrast, there is some evidence that funds (weakly) outperform during their first year of existence.
