Portfolio Diagnostics

Paste up to 20 positions and see where your risk actually sits: concentration, the positions driving portfolio risk, and your diversification benefit. ● Runs in your browser — nothing uploaded or stored

Concentration & risk contribution

Euler risk contributions

Paste positions above, or load the example, to run the diagnostics.

Simplified and illustrative. Standalone risk uses indicative rating-based factors (unrated ≈ BB); correlations use stylised same-sector / same-geography assumptions. Risk contributions are Euler contributions and sum to portfolio risk. Our full assessment uses calibrated PD/LGD, published correlation matrices, and Vasicek economic capital.
