What is an SEC 8-K filing?
An SEC 8-K is the filing a public company uses to announce a material event that shareholders should know about between its regular quarterly and annual reports.
What counts as an 8-K event
Examples include earnings releases, executive changes, mergers and acquisitions, and bankruptcies. Each 8-K is organized into numbered items that describe the type of event being reported.
Why it matters
Because 8-Ks report events as they happen, they are one of the fastest official windows into something changing at a company.
How QuantConomy surfaces it
QuantConomy parses 8-K items, scores how material each one is, and can raise a CORPORATE_EVENT signal tied to the company and the specific item.
Questions
How quickly must an 8-K be filed?
Companies generally file an 8-K within four business days of the event, though some items have different timing. The rules are set by the SEC.
What is an 8-K item number?
An 8-K groups disclosures into numbered items (for example Item 2.02 for results of operations). The item number tells you what kind of event the filing reports.
