Can I use this for multi-asset portfolio analysis?

Yes, it includes a PortfolioRisk class designed to handle asset weightings, covariance matrices, marginal risk contributions, and diversification ratios.

Does it support real-time or rolling risk monitoring?

The skill includes patterns for rolling risk metrics, allowing you to track how volatility, VaR, and other indicators evolve over time-based windows.

Which Value at Risk (VaR) methods are supported by this skill?

The skill provides patterns for Historical, Parametric (Normal), and Cornish-Fisher VaR, the latter of which accounts for skewness and kurtosis in non-normal return distributions.

What risk-adjusted performance metrics are included?

It includes standard metrics like the Sharpe and Sortino ratios, as well as the Calmar ratio for drawdown-relative performance and the Omega ratio for overall gain/loss probability.

Are the calculations compatible with standard Python libraries?

Absolutely. The implementation patterns are built using NumPy, Pandas, and SciPy, ensuring seamless integration with existing data science and financial pipelines.
