Regime-conditioned stress interpretation
What matters in this regime?
In the current regime, broad equity shocks remain relevant when the portfolio is concentrated in the largest holding. Volatility shocks matter directly only when vega exposure is present.
Athena Stress Narrative
Scenario-specific risk interpretation
Run a scenario to generate a portfolio-specific stress narrative. Athena will explain loss channels, offsets, liquidity/rates/volatility effects, and what to inspect next.
