Conducting, to our knowledge, the largest study ever of five-minute equity market returns using state-of-the-art machine learning models trained on the cross-section of lagged market index constituent returns, we show that regularized linear models and nonlinear tree-based models yield...

Motivated by the recent changes made to the regulatory environment that governs how banks calculate minimum capital requirements Liu and Stentoft (2020) seek to answer the question of how regulation affect banks' choice of risk-management models, whether it incentivizes them to use correctly...

With approximately 900 million observations we conduct, to our knowledge, the largest study ever of intraday stock return predictability using machine learning techniques finding consistent out-of-sample predictability across market, sector, and individual stock returns at various time horizons....
