- Quarterly fundamentals are aligned to SEC filing dates before daily valuation studies.
- The promoted universe starts from active NYSE/NASDAQ common stocks, then applies price and dollar-volume gates.
- Snapshot-only tables such as analyst consensus, DCF, us_ratios, and us_key_metrics are intentionally excluded from historical evidence.
- Overlapping event windows are descriptive distributions, not independent samples.
