Signal DNA
Disclosure-drift alpha — its full record.
What it does
Measured how a company's filing language changes from one report to the next; the earlier claim of excess return derived from this measurement has been withdrawn.
Who built it
BaselineWatch Research. Withdrawn by BaselineWatch after its own re-measurement.
Sources
SEC 10-K and 10-Q filings.
Testing & verification history
4 NOV 2026
Return claim withdrawn
The published excess return used factor data from the wrong window. Re-measured over the holding period, it is not significant, so the claim was withdrawn.
4 NOV 2026
Framework kept
The forensic-linguistics framework, the dictionary and the filing data behind it remain in use.
What this is not
Not for sale and not a claim. This page is kept so the record stays public.
The graveyard
Every signal we killed or withdrew, with the reason.
