PublicationThe Lasso and the Factor Zoo - Predicting Expected Returns in the Cross-Section( 2022-11-17)We investigate whether Lasso-type linear methods are able to improve the predictive accuracy of OLS in selecting relevant firm characteristics for forecasting the future cross-section of stock returns. Through extensive Monte Carlo simulations we show that Lasso-type predictions are superior to OLS when type II errors are a concern. The results change if the aim is to minimize type I errors. Finally, we analyze the predictive performance of the competing methods on the US cross-section of stock returns between 1974 and 2020 and show that only small and micro-cap stocks are highly predictable through-out the entire sample.Type: journal articleJournal: ForecastingVolume: 4Issue: 4
