Researchers have developed a more efficient neural network for optimizing portfolios to minimize variance, even with aggressive leverage. This new model significantly reduces the number of learnable parameters compared to previous architectures, from nearly 40,000 to just over 2,000. In testing, the compact network achieved lower portfolio variance than state-of-the-art benchmarks without sacrificing expected returns. The findings suggest that end-to-end variance-minimization architectures can offer substantial gains in parameter and capital efficiency. AI
