Diffusion model enhances stock portfolio optimization with factor analysis

Researchers have developed a new conditional diffusion model for portfolio optimization, utilizing a Diffusion Transformer architecture. This model learns stock return distributions based on asset-specific factors and cross-asset dependencies. It has demonstrated superior performance against benchmarks in the Chinese A-share market for daily mean-variance and mean-CVaR optimization, even when accounting for transaction costs and constraints.

    Factor-Based Conditional Diffusion Model for Contextual Portfolio Optimization

    arXiv:2509.22088v3 Announce Type: replace-cross Abstract: We propose a novel conditional diffusion model for contextual portfolio optimization that learns the cross-sectional distribution of next-day stock returns conditioned on high-dimensional asset-specific factors. Our model …
