What Are 8-K Filing Signals?
Weekly refresh
8-K filings are how public companies disclose material events to the SEC as they happen: a CEO departure, a major acquisition, a data breach, or entry into a significant contract. Companies must file within four business days of the triggering event, making the 8-K the fastest confirmed source of corporate intelligence from a regulatory filing.
Autobound extracts 83 signal subtypes from 8-K filings, organized by the SEC's item numbering system: Item 1.01 for new material agreements, Item 2.01 for asset acquisitions or dispositions, Item 5.02 for executive departures, and so on. Each item maps to a different sales opportunity, and because these events are time-sensitive (a new CEO opens a vendor reevaluation window; an acquisition forces stack consolidation), acting fast matters.

How we build this signal
How we build each 8-K signal
Every week a job reads the previous week's 8-K filings and runs each through five stages. Code checks every model answer before it ships.
- Relevance floor
- 0.7
- Model reads per filing
- 3
- Refresh
- Weekly
- 01
Collection
Each Tuesday a job queries an SEC filings index for every company in our public-company list and collects the 8-K filings dated in the previous week.
- 02
Section extraction
We fetch the filing and keep the parts that carry business detail. For an 8-K, that is the event items, such as material agreements, acquisitions, results, new debt, auditor changes and officer or director changes. If none is found, a trimmed copy of the full text is used.
- 03
Three focused reads
A model reads each filing three times, once per theme: leadership and strategy, technology and operations, financial health and risk. Each read picks subtypes from a closed list, uses each once and must quote the filing.
- 04
Quality gates
Code drops any signal with an unlisted subtype, a relevance score under 0.7, or evidence that is under 50 characters, a table fragment or boilerplate such as safe-harbor text. A filing whose company has no website ships nothing.
- 05
Dedup and delivery
One filing yields at most one signal per subtype. Each signal is fingerprinted on form, subtype, ticker and filing date, and a shipped fingerprint is never delivered again. Records are schema-checked before upload.
8-K Signal Data Schema
8-K signals capture material corporate events with SEC item classification. Each signal includes the specific 8-K item type, event details, and sales relevance scoring.
