Beyond Prediction: Smarter Portfolio Optimization for Real-World Markets

08.01.2026 by qfx

During the intense market volatility of early 2020, robust optimization and a conservative stochastic programming approach-incorporating transaction costs-yielded nearly identical portfolio allocations, demonstrating that, under extreme stress, the inherent constraints and penalties within the latter already provided sufficient robustness without requiring additional complexity from the former-a finding suggesting diminishing returns from further robustness enhancements in highly constrained optimization problems.

A new approach to portfolio management directly links learning objectives to investment decisions, delivering consistently improved performance and resilience.
