PurposeThis study aims to provide a comprehensive overview of asset allocation by conducting a systematic literature review and a bibliometric analysis.Design/methodology/approachEmploying a Preferred Reporting Items for Systematic Reviews and Meta-Analyses-based methodology allows for rigorous mapping of the academic landscape.FindingsAn analysis of this topic reveals a significant increase in asset allocation research since 2013, driven by a growing focus on advanced modeling and risk metrics. This study identifies distinct research clusters, with topics such as behavioral finance and alternative assets gaining prominence in the literature. Furthermore, the most prolific authors on this topic are Zhang, WG, and Zhou, XY.Research limitations/implicationsThis review contributes to a more comprehensive understanding of this field by delineating the evolution and diversity of asset allocation models.
