Portfolio Optimization

소개

Enhance financial applications with high-speed portfolio optimization techniques by leveraging Python C extensions to offload heavy numerical workloads. This skill provides a comprehensive framework for optimizing operations like covariance matrix calculations, dot products, and risk metrics, specifically targeting performance gains of 1.2x or greater for portfolios with thousands of assets. It covers the end-to-end development lifecycle, including NumPy C API integration, memory layout management, and rigorous verification strategies to ensure that performance improvements never compromise mathematical precision.
