Frequently asked questions
What is an SEC Form 8-K?
An 8-K is how a public company tells investors about a major event between its quarterly reports, such as a merger, a CEO change, bankruptcy, or a delisting. Companies usually have four business days to file one.
How are these events grouped?
Massive reads the text of each 8-K and classifies it by event type, so you can follow one kind of disclosure across companies instead of reading every filing. Each page above collects one event type.
How current is this?
The pages cover the last 90 days and refresh through the day. For the full, continuously updated record, the Massive 8-K disclosures API returns every filing with its classification.
