Collect evidence and execute five institutional-method programs
The system runs original Concordal research, quant diagnostics and five independent method engines. Each program returns applicability, calculations, company evidence, missing gates and its own conclusion; insufficient evidence is withheld rather than replaced with a teaching example.
Goldman Sachs · Commodity Primer：commodity transmission program
Enter a ticker above to run the real commodity program inside integrated analysis (it stays a neutral N/A without validated commodity inputs). The debugger below computes timespread, curve state and the carry proxy from fixed formulas; example values never enter real conclusions.
Framework lineage: Commodity Primer for Portfolio Managers (11 May 2026) · PDF physical pages p3; p4–8; p13–14; p15–20; p21–23; p24–26 · methodology lineage only, never company evidence
Marginal-cost anchor and timespread (p4–8)
Spot ≈ long-dated marginal-cost anchor + inventory-tightness adjustment.
The long-dated contract anchors marginal production cost.
spot − long-dated
(spot/long-dated − 1) × 100
sign only; no invented threshold
- Both prices must be finite and positive; otherwise the program fails closed with no curve state.
- Backwardation/contango reflect the immediacy premium versus storage cost — never a trade signal.
Futures return and roll proxy (p13–14)
(front − next)/front × 100 · a PROXY only, not a forecast of realised roll yield
- Futures return = price return + roll yield; front contracts may maximise roll gains in backwardation while farther maturities may reduce roll drag in contango.
- The proxy computes only when both contract prices are finite and positive.
Inventory-to-use (p4–8 · p24–26)
- Inventory-to-use is reported raw only; tight/loose classification and calibration parameters require a validated calibration program — this program never infers them.
- Appendix horizon framework: energy = high storage-cost elasticity / short horizon; metals = lower elasticity / longer horizon.
Inflation-regime hedge mapping (p15–20) · validated regimes only
| Regime | Hedge |
|---|---|
| Late-cycle | Cyclical commodities |
| Supply disruption | Broad basket excluding precious metals |
| Institutional-credibility risk | Gold |
- The mapping publishes only from an explicitly validated regime (validated=true, in the enum, with resolvable sources); the program never guesses a regime from narrative.
- Commodity-linked equities are not equivalent to direct commodity exposure; the warning ships with every published mapping.
- Basket checks (p21–23): benchmark alignment, investor location, regime tilt, dollar sensitivity, enhanced roll; no portfolio weight is published without a validated optimizer.
