5. Text → Numeric Key Factors

No valid numeric parameter shock was produced. Downstream valuation values remain zero and are explicitly recorded as unavailable.

6. Pricing Models and Weighted Valuation Change

Valuation unavailable because no valid parameter shock was produced.

7. Priced-In and Expectation-Gap Adjustment

implied_delta = Σ(model weight × Σ(parameter shock × elasticity))
priced_in = max(aligned price drift, historical information diffusion)
expected_residual = implied_delta × (1 - priced_in) × reaction_efficiency

Quantity	Value	Interpretation
Implied fair-value change	+0.00% (+0 bps)	Before market-pricing adjustment
Already priced in	0.0%	Price and diffusion channels
Historical reaction efficiency	default	Insufficient history
Expected residual move	+0.0 bps	Remaining quantified expectation gap

8. Multi-Horizon Numeric Forecast

Horizon	Direction code	Magnitude	Confidence

10. Audit Notes

• Every reusable numeric field from the narrative report is included above.
• Parameter names are restricted to the asset-specific registry.
• Model weights sum to 100%; all model contributions are retained.
• Historical efficiency uses a bounded median to reduce outlier influence.
• Direction codes are +1 for up, 0 for flat/unavailable, and -1 for down.

The use of a structured numeric flow to capture and analyze market dynamics is a compelling approach—particularly the way you highlight the relationship between information gaps and expectation gaps. This method could benefit from a more granular analysis of historical data to refine the “reaction efficiency” metric further, potentially improving future predictions. If you’re planning to enhance the pricing model aspects discussed, I’d be interested in contributing if you’re looking for additional engineering support in that area. What challenges have you encountered in translating the numeric factors into actionable trading strategies?
