Track over time:
Check all items: 8-Ks often contain multiple items - don't focus only on headlines.
Read exhibits: Press releases and agreements in exhibits contain critical details.
Note timing: Friday afternoon or holiday filings may attempt to minimize attention.
Track patterns: Frequent 8-Ks may signal ongoing corporate activity.
Cross-reference: Compare 8-K disclosures with subsequent 10-Q/10-K filings.
Monitor amendments: 8-K/A filings update or correct prior disclosures.
