How does the skill handle correlation between different assets?

It utilizes covariance matrices and Cholesky decomposition within its portfolio VaR and Monte Carlo functions to accurately model how asset correlations impact total portfolio risk.

What is the difference between VaR and Expected Shortfall in this skill?

VaR (Value-at-Risk) identifies a loss threshold at a specific confidence level, whereas Expected Shortfall (CVaR) calculates the average loss that occurs when that threshold is exceeded, providing a more comprehensive view of tail risk.

Can I use this skill for portfolios with non-linear instruments like options?

Yes, the skill provides Monte Carlo simulation patterns specifically designed to handle non-linear payoffs and non-normal return distributions that parametric models often miss.

Does this skill support regulatory risk calculations?

The skill implements industry-standard formulas for VaR and Stress Testing used in various regulatory capital frameworks, though it should be calibrated to your specific local compliance requirements.
