- Build your book. Search a ticker (101 names) and click it, or use the custom row — pick a sector for a quick sector exposure, or sector + a specific ticker.
- Set weights. Use − / + or type a number. Weights auto-normalise to % of book; they need not sum to 100.
- Pick a scenario. Tap Ceasefire, Central War, or Full Closure — the score recomputes instantly, in your browser.
- Read the score. Green = net beneficiary, red = net exposed: how much the book moves vs pre-conflict normal under that scenario.
- See where it hits. “By channel” shows the drivers (oil, growth, FX…); “Most exposed holdings” ranks positions by weighted contribution.
Sector-level estimates for research, not investment advice. Live prices show for the core universe; other names are scored and marked “score-only”.
