We propose a new method to select amongst a large group of candidate factors — many of which might arise as a result of data mining — that purport to explain the cross-section of expected returns. The method is robust to general distributional characteristics of both factor and asset returns. We allow for the possibility of time-series as well as cross-sectional dependence. The technique accomm...
