Mutual Funds’ Conditional Performance Free of Data Snooping Bias

Hsu, P-H., Kyriakou, I. ORCID: 0000-0001-9592-596X, Ma, T. & Sermpinis, G. (2024). Mutual Funds’ Conditional Performance Free of Data Snooping Bias. Journal of Financial and Quantitative Analysis, pp. 1-53. doi: 10.1017/s0022109024000097


We introduce a test to assess mutual funds’ “conditional” performance that is based on updated information and corrects data snooping bias. Our method, named the functional False Discovery Rate “plus” (fF DR+), incorporates fund characteristics in estimating fund performance free of data snooping bias. Simulations suggest that the fF DR+ controls well the ratio of false discoveries and gains considerable power over prior methods that do not account for extra information. Portfolios of funds selected by the fF DR+ outperform other tests not accounting for information updating, highlighting the importance of evaluating mutual funds from a conditional perspective.
