【摘要】We select mutual funds in real time by combining individual fund holdings and a large number (94) of stock characteristics to compute fund-level exposures to characteristics on the basis of the stocks they hold. The majority of funds are exposed---both positively and negatively---to approximately 40-50 characteristics. In addition, fund performance is non-linearly related to fund characteristics and their interactions. This feature proves important when we predict fund performance, as machine learning methods such as boosted regression trees (BRTs) significantly outperform standard linear frameworks. Our BRT-generated forecasts encompass the ones generated by the predictors of mutual fund performance that have been proposed in the literature so far.
