What FlinchLab is building, and why
Every public company in the US tells the market what happened through an SEC 8-K. Most data on those filings stops at the number in the header. We are building the version that reads the filing, and shows its working.
What is the problem?
An 8-K arrives with an item number: 2.02 for results, 5.02 for executive changes, 3.01 for listing problems. But one number holds opposite events. A delisting notice can be a merger closing or an exchange forcing a company out. A filing about an executive can be a routine pay change or a sudden departure. Treating them as one event averages a non-event with a crisis. See the 8-K item number is not the event.
Who gets left out?
Coverage usually follows the big indexes. But 2,976 different companies filed a delisting notice between January 2022 and August 2026, about twice the number in the S&P Composite 1500, so most of those events sit outside the indexes. For delisting notices, auditor changes and restatements the filing is often the first public word. See where 8-K events live.
Why does timing matter?
98.6% of earnings 8-Ks are filed outside market hours, and the reaction to what a release says about the outlook shows up in the overnight gap. A label that cannot say when the information became public cannot say what it was worth. See earnings guidance moves the stock overnight.
What are we building?
- Every 8-K, labelled for every filer since January 2022: 320,578 filings, not just index members.
- The source sentence. Each label that states what a company did cites the sentence in the filing that says so, so any row can be checked.
- The acceptance time. Every label carries the filing’s public acceptance time and uses only what the filing said.
- A same-day feed and the history, released one event type at a time, each tested before release.
- The price record for each event type: how stocks have moved around it against peers.
What happened to the earlier release?
Version 0.1 was built on a smaller set of companies, and we found problems in how it was processed. We retired it rather than leave figures online that we could not fully stand behind, and we are rebuilding on every filer with each label checkable against its source sentence.
Where does it stand?
Earnings releases are first: nearly 5,000 labelled to date, more every night. Delisting notices and executive changes come next. Early access opens at the end of November 2026. Figures as of 6 October 2026.
