Security master change feed · Early access
A daily, filing-cited record of US equity identity changes
Ticker and name changes, listing status, mergers and reorganisations, and splits, each tied to the SEC filing that supports it, with corrections to earlier editions published in the open.
The feed is in development and not yet delivered. Join the list to hear first, and to get it free for about a year as an early client.
What each edition contains
One edition with each daily data release
Identity and status events
Ticker and name changes, listing status (Form 25 and 8-K Item 3.01), mergers and reorganisations, and splits.
A filing behind every event
Each event carries its effective date and a citation to the SEC filing that supports it.
Corrections in the open
Each edition lists changes to facts published in earlier editions: the old value, the new value, the edition it first appeared in, and the reason.
Point-in-time known-as-of dates
Every fact carries the edition date on which it became known, so you can reconstruct what was known on any past day.
Open keys
FIGI, SEC CIK, the RiskModels security id, and ticker. No identifiers from licensed data feeds.
Not in scope
- Dividends, tender offers and holder elections
- Price and model-value corrections (these go in the full RiskModels release notes)
- Non-US listings
Event types are limited to what SEC filings support. The feed is the identity part of each RiskModels data release, the same record the RiskModels API uses to resolve historical tickers.
Illustrative format
What an edition looks like
Placeholder values, not a real security or filing. Field names may change before the first edition; early-access members see the spec first.
