Quick Summary: The SEC Filing Forensics Framework
Reading SEC filings is about finding the Source of Truth before it is filtered by headlines or PR.
Retail waits for summaries.
Institutions go straight to raw disclosures.
The Big Three Filings:
10-K (Annual): Full health check, audited, long-term roadmap
10-Q (Quarterly): Early signals, trend shifts, financial stress
8-K (Current): Immediate events, real-time catalysts
The 80/20 Rule:
Focus only on:
MD&A → why numbers changed
Risk Factors (Item 1A) → new threats
Footnotes → hidden liabilities
The F.I.L.I.N.G.S. Model:
Financials, Insiders, Liquidity, Irregularities, Notes, Guidance, Significant Events
Golden Rule:
The edge is not in what is written.
It is in what changed.
The stock rallies.
Then it drops days later.
Why?
Because the real information was not in the headline.
It was buried inside the filing.
Most traders react to news.
Smart traders read SEC filings.
What is SEC Filing Analysis in Trading?
SEC filing analysis is the process of using 10-K, 10-Q, 8-K, and Form 4 disclosures to identify risks, opportunities, and changes before the market fully reacts.
Instead of asking:
“Did earnings beat?”
You ask:
“What changed that the market has not priced yet?”

Frequently Asked Questions:
Where can I find SEC filings for a specific stock?
The official source is SEC EDGAR.
Search by ticker or company name.
Advanced tools like Bamboo or WhaleWisdom help track insider trades and institutional activity.
What is the primary difference between a 10-K and a 10-Q?
A 10-K is audited and comprehensive.
A 10-Q is unaudited but provides early warning signals before they appear in annual reports.
What triggers a Form 8-K filing and why does it move stocks?
Triggered by material events like CEO exits, M&A, or delisting notices.
Because filings occur within 4 days, they often lead to sharp price moves before news spreads.

The biggest signal is new or changed language.
If new risks appear or wording strengthens, it signals a material shift in business risk.
