Source and calculation coverage
| module | status | reason |
|---|---|---|
| ratios/models | unavailable | Financial statement ratios and DuPont require matching annual statement evidence; choose AQ06 for those calculations. |
| fixedincome | unavailable | No specific bond, coupon schedule or swaption market observations were supplied by this stock-market demonstration. Bond and swaption outputs are not invented. |
| economics | unavailable | No dated macro release/vintage dataset was selected. Market price returns are not substituted for economic releases. |
| portfolio/causal econometrics | unavailable | Portfolio optimization and causal research require explicit constraints, instruments and validation; this bounded demonstration does not imply those workflows ran. |
Unavailable measurements retain their specific missing evidence. A method being present in the library does not mean the required market inputs exist.
Measures that need additional evidence (4)
- ratios/models: Financial statement ratios and DuPont require matching annual statement evidence; choose AQ06 for those calculations.
- fixedincome: No specific bond, coupon schedule or swaption market observations were supplied by this stock-market demonstration. Bond and swaption outputs are not invented.
- economics: No dated macro release/vintage dataset was selected. Market price returns are not substituted for economic releases.
- portfolio/causal econometrics: Portfolio optimization and causal research require explicit constraints, instruments and validation; this bounded demonstration does not imply those workflows ran.

Método de cálculo
Public yfinance observations are requested through tomorrow because Yahoo's end date is exclusive.
Only verified completed XNYS sessions at selection time enter daily studies; incomplete current-day bars are excluded.
The selection date is fixed once in Africa/Tunis. The observed source cutoff is displayed separately.
methods receive observed input. Missing values are not filled or replaced with defaults.
Adjusted-close returns are descriptive provider-adjusted returns, not a point-in-time data-vintage backtest.

Alcance y revisión
This is a bounded public-data research demonstration; no transaction execution, accounts or customer records are used.
Sources may be delayed or revised. Current observations and provider licensing must be reviewed before commercial redistribution.
Narratives are generated deterministically from calculated evidence. No language model is claimed to have authored this run.
The short GARCH demonstration has no independent predictive-accuracy or interval-coverage validation.
La fecha de ejecución permanece fija para esta selección. Las observaciones de mercado y los periodos de información financiera pueden precederla. Las estimaciones son cálculos de investigación, no precios futuros observados.
