arXiv:2607.00581v1 Announce Type: new Abstract: Sparse tangent portfolio optimization aims to learn an interpretable, low-cardinality portfolio in the tangency direction of the mean-variance frontier. However, the associated cardinality-constrained formulation is NP-hard, and standard predict-then-optimize pipelines often misalign forecasting accuracy with downstream portfolio quality. We propose an end-to-end decision-focused learning framework that reformulates Sharpe ratio maximization as a Disciplined Parametrized Programming (DPP)-compliant convex programming layer and replaces discrete s
This development arises from ongoing research in applying advanced AI and optimization techniques to classic financial problems, driven by increased computational power and novel algorithmic approaches.
It introduces a method to create more efficient and interpretable investment portfolios by directly optimizing for financial objectives, potentially improving investment performance and reducing risk.
The approach shifts from traditional predict-then-optimize models to an end-to-end decision-focused framework, better aligning predictive models with real-world financial outcomes.
