Portfolio Risk Analyzer

Overview

This skill performs a comprehensive, portfolio-level risk analysis. It goes beyond individual position risk to quantify systemic and correlated risks across the entire portfolio.

Core Features:

• Value at Risk (VaR): Calculates 95% and 99% VaR using Parametric, Historical, and Monte Carlo methods.
• Max Drawdown Analysis: Identifies historical and potential future maximum drawdowns.
• Correlation Matrix: Visualizes how positions move in relation to each other, highlighting diversification benefits or weaknesses.
• Stress Testing: Simulates portfolio performance during historical market crises (e.g., 2008 GFC, 2020 COVID crash, 2022 rate hikes).
• Concentration Risk: Identifies over-concentration in specific sectors, factors, or individual positions.
• Beta Calculation: Measures portfolio volatility relative to benchmarks (SPY, QQQ).
