risk-analysis
Risk-analysis provides quantitative methods for measuring portfolio risk through Value at Risk, Conditional Value at Risk, maximum drawdown analysis, and Monte Carlo simulation. It includes historical and parametric VaR calculation, tail-risk analysis via extreme value theory, and stress-testing frameworks using both historical scenarios and hypothetical shock models.
Risk-analysis calculates VaR, CVaR, and maximum drawdown to assess portfolio risk exposure.

AI-generated answers based on this skill's SKILL.md and metadata
How does risk-analysis calculate VaR and CVaR for portfolio risk?
Risk-analysis computes Value at Risk and Conditional Value at Risk (expected shortfall) using both historical and parametric methods. VaR measures the maximum loss at a given confidence level, while CVaR captures the expected loss beyond that threshold. The skill supports multiple calculation approaches to suit different portfolio structures and risk profiles.
What monte carlo simulation capabilities does risk-analysis offer?
Risk-analysis runs Monte Carlo simulations to model tail risk and extreme scenarios across your portfolio. By generating thousands of potential price paths, it reveals how your holdings behave under stress conditions and helps identify tail-risk exposures that traditional metrics might miss.
Can risk-analysis stress test my portfolio against historical crises?
Yes. Risk-analysis includes stress-testing frameworks that replay historical market shocks—such as the 2008 crisis—against your current portfolio. It also supports hypothetical scenario analysis, letting you model custom shocks to interest rates, volatility, or asset correlations to assess resilience.
How does risk-analysis analyze tail behavior and extreme value theory?
Risk-analysis applies extreme value theory and Generalized Pareto Distribution (GPD) fitting to analyze tail behavior. This approach captures fat-tail risk and rare events more accurately than normal-distribution assumptions, helping you understand the true probability and magnitude of extreme losses.
What risk-control recommendations does risk-analysis generate?
Risk-analysis generates actionable risk-control recommendations based on drawdown analysis, volatility metrics, and stress-test results. These suggestions help you rebalance, hedge, or adjust position sizes to align your portfolio with your risk tolerance and performance objectives.
Does risk-analysis support maximum drawdown and recovery analysis?
Risk-analysis measures maximum drawdown to quantify the largest peak-to-trough decline in your equity curve. It also analyzes recovery patterns, helping you understand how long portfolios typically take to bounce back from losses and informing your risk-management strategy.

Risk Measurement and Stress Testing
Overview
Systematic risk-measurement methodology covering VaR/CVaR calculation, Monte Carlo simulation, stress-test design, and tail-risk analysis. It provides risk evaluation for backtest results and risk-control constraints for asset allocation.
Risk Measurement Methods
1. VaR (Value at Risk)
Definition: the maximum expected loss over a given horizon at a specified confidence level.
Three Calculation Methods
| Method | Formula / Steps | Advantages | Disadvantages |
|---|---|---|---|
| Historical simulation | Sort historical returns and take the quantile | No distribution assumption | Depends on historical samples |
| Parametric (normal) | VaR = μ - z_α × σ |
Easy to compute | Assumes a normal distribution |
| Monte Carlo | Simulate N paths and take the quantile | Flexible | Computationally intensive |
