We calculate 148 firm characteristics and use them to feed a repertoire of different models. The algorithms extract predictability mainly from simple yet popular factor types—such as momentum, reversal, value, and size. All individual models generate substantial economic gains; however, combining them proves particularly effective. Despite the overall robustness, the machine learning performance depends heavily on firm size and availability of recent information. Furthermore, it varies internationally along two critical dimensions: the number of listed firms in the market and the average idiosyncratic risk limiting arbitrage.  \nKeywords: machine learning, return predictability, international stock markets, the cross-section of stock returns, forecast combination, asset pricing, firm size  \nJEL Codes: C52, G10, G12, G15  \nThis version: 30 June 2023  \n* We thank Vitor Azevedo, Turan Bali, Hendrik Bessembinder, David Blitz, Guillaume Coqueret, Guanhao (Gavin) Feng, Matthias Hanauer, Fabian Hollstein, Tobias Hoogteijling, Theis Ingerslev Jensen, Tobias Kalsbach, Herald Lohre, Alexandre Rubesam, Laurens Swinkels, Andea Tamoni, Pim van Vliet, and Guofu Zhou for helpful comments and suggestions, as well as seminar participants at Technical University of Munich, Robeco, Ono Academic College, American University of Sharjah, and American University in Dubai.

Introduction  \nA recent merger between machine learning and asset pricing research has raised hopes for a solution to the factor zoo problem found within stock markets . So far, the evidence has been promising. Studies from the U.S. and China have demonstrated that machine learning models can effectively explain and predict the cross-section of stock returns.1 Nevertheless, the evidence from individual markets may not necessarily hold elsewhere.2 Return predictability depends on the region or country characteristics that affect input data and model performance.3 Furthermore, the complexity of machine learning techniques—as well as the diversity of their design—augments the risk of data dredging. To alleviate these concerns, extensive out-of-sample evidence across many countries and models is necessary.  \nAgainst this backdrop, this study combines machine learning with asset pricing research to comprehensively examine cross-sectional return pre","cbCaimRuoKgdW4E4","https://ap.wps.com/l/cbCaimRuoKgdW4E4","pdf",1911994,57,"English","# Abstract\n# Introduction\n## Research backdrop and motivation\n## Data and methodology overview","[{\"question\":\"What is the main research focus of the document?\",\"answer\":\"It examines how machine learning can predict cross-sectional stock returns across 46 international markets and identifies drivers of performance differences across countries.\"},{\"question\":\"How are return predictability models constructed and evaluated?\",\"answer\":\"The study computes 148 firm characteristics from three decades of CRSP and Compustat data, then feeds them into a set of 11 representative algorithms, including forecast combination, and assesses predictive ability and economic gains.\"},{\"question\":\"Which factor types and conditions most influence predictive performance?\",\"answer\":\"Predictability is extracted mainly from popular factor types such as momentum, reversal, value, and size.
