We compare two bootstrap methods for assessing mutual fund performance. Kosowski, Timmermann, Wermers and White (2006) produces narrow confidence intervals due to pooling over time, while Fama and French (2010) produces wider confidence intervals because it preserves the cross-correlation of fund returns. We then show that the average UK equity mutual fund manager is unable to deliver outperformance net of fees under either bootstrap. Gross of fees, 95% of fund managers on the basis of the first bootstrap and all fund managers on the basis of the second bootstrap fail to outperform the luck distribution of gross returns.
