Risk Metrics Calculation
Comprehensive risk measurement toolkit for portfolio management, including Value at Risk, Expected Shortfall, and drawdown analysis.
When to Use This Skill
- Measuring portfolio risk
- Implementing risk limits
- Building risk dashboards
- Calculating risk-adjusted returns
- Setting position sizes
- Regulatory reporting
Core Concepts
1. Risk Metric Categories
| Category | Metrics | Use Case |
|---|---|---|
| Volatility | Std Dev, Beta | General risk |
| Tail Risk | VaR, CVaR | Extreme losses |
| Drawdown | Max DD, Calmar | Capital preservation |
| Risk-Adjusted | Sharpe, Sortino | Performance |
2. Time Horizons
Intraday: Minute/hourly VaR for day traders
Daily: Standard risk reporting
Weekly: Rebalancing decisions
Monthly: Performance attribution
Annual: Strategic allocation
Detailed patterns and worked examples

Best Practices
Do's
- Use multiple metrics - No single metric captures all risk
- Consider tail risk - VaR isn't enough, use CVaR
- Rolling analysis - Risk changes over time
- Stress test - Historical and hypothetical
- Document assumptions - Distribution, lookback, etc.
Don'ts
- Don't rely on VaR alone - Underestimates tail risk
- Don't assume normality - Returns are fat-tailed
- Don't ignore correlation - Increases in stress
- Don't use short lookbacks - Miss regime changes
- Don't forget transaction costs - Affects realized risk

dask
Distributed computing for larger-than-RAM pandas/NumPy workflows. Use when you need to scale existing pandas/NumPy code beyond memory or across clusters. Best for parallel file processing, distributed ML, integration with existing pandas code. For out-of-core analytics on single machine use vaex; for in-memory speed use polars.
