A new research paper introduces a robust framework for mean-variance portfolio selection that promotes sparsity in asset allocations. The method incorporates uncertainty in the mean return vector using an ellipsoidal uncertainty set, leading to a robust sparse optimization problem. The paper details a branch-and-bound algorithm designed to efficiently solve these problems, demonstrating its effectiveness through computational experiments on real market data. AI
