Ruinius Financial Modeling (Phase 6)
All modeling logic is consolidated into a single script that executes the complete sequence: WACC → Assumptions → DCF → Intrinsic Value.
- Execute the script:
python skills/financial_modeling/scripts/calculate.py {TICKER} {TICKER_metadata_path} - Verify it threw no errors.
What the Script Does
| Step | Action | Details |
|---|---|---|
| 1 | Fetch Market Data | Calls tools/market_data.py profile {TICKER} for share price, beta, market cap |
| 2 | Read Historical Data | Parses Financial History table from metadata for L4Q averages |
| 3 | Read Qualitative Data | Parses Economic Moat, Margin Outlook, Growth Outlook from metadata |
| 4 | Calculate WACC | CAPM with Blume-adjusted beta, capital structure weights |
| 5 | Generate Assumptions | Three-stage DCF assumptions blending historical trends + qualitative outlook |
| 6 | Run DCF Projections | 10-year projections with interpolated growth/margin, terminal value via Gordon Growth |
| 7 | Compute Intrinsic Value | Equity bridge: EV + Cash - Debt → Per Share |
| 7b | FX & ADR Conversion | If reporting currency != USD, convert IVPS to USD. Apply ADR ratio to share count if applicable |
| 8 | Update Metadata | Replaces WACC, Assumptions, DCF Model, and Intrinsic Value sections in markdown |
