Connect earnings and filings
Use this path if you want to understand how calls, filings, releases, and verification work together.
Learn before you click
Use a repeatable process before opening a company page
These paths are built for readers who want a method, not another pile of links. Each one starts with the question to ask, points to the official SEC source, and then shows where Quantfil's filing pages fit into the workflow.
Path 1
From Earnings Release to Filing Verification
Use this when the market is reacting to a release, but you want to verify whether the later filing supports the same story.
Original filing visual: release claim, 10-Q verification, cash flow confirmation, and next-quarter watch item.
- Capture the headline claim from the earnings release or call.
- Find the matching filing in EDGAR and check MD&A, statements, and footnotes.
- Compare cash flow, working capital, and segment language against the headline.
- Write down one item that would confirm or weaken the story next quarter.
Path 2
How to use EDGAR without getting lost
Use this when the source document matters, but the official search flow feels slower than it should.
Original filing visual: ticker or CIK search, form filter, filing detail page, and source-document checklist.
- Search by company name, ticker, or CIK, then confirm you have the right issuer.
- Filter by form type instead of scrolling through every filing.
- Open the filing detail page before jumping into exhibits or XBRL files.
- Use Quantfil only after you know which source filing you are trying to understand.
Path 3
The Statement Trap: Why investors misread the Income Statement
Use this when a company looks better on revenue, EPS, or margin, but you have not yet tested whether the improvement is durable.
Original filing visual: income statement headline, cash flow check, balance sheet pressure, and footnote explanation.
- Start with revenue, operating income, and net income, but do not stop there.
- Check whether operating cash flow confirms the reported improvement.
- Look for balance sheet pressure in receivables, inventory, deferred revenue, and debt.
- Read the accounting footnotes before treating the improvement as operational.

Questions people usually have before filing research starts to feel natural
Learning paths
Progress from beginner to advanced without guessing what to read next
These paths are meant to feel like courses without sounding like homework. Start with the level that matches your comfort with filings today.
Beginner path
Start with the form basics, then learn how the main statements fit together before opening a live filing page.
Intermediate path
Move from definitions into workflow: compare filings, read MD&A carefully, and learn how earnings and filings connect.
Advanced path
Use the advanced path when you want to focus on footnotes, red flags, verification frameworks, and business-quality judgment.
Sector path
Use this path when the same filing form means different things in different industries.
Flagship workflows
Workflows that teach investors what to do next
These pages are designed to be reused. They show how to move from the filing to the judgment, not just how to define the document.
What investors get wrong
Common mistakes that make filing analysis weaker than it should be
These pages focus on the ways investors over-trust headlines, over-read single metrics, or skip the disclosures that would have changed the conclusion.
Case studies
Real filing reads using tracked companies
These case studies show how a filing-first process works when the company is real, the issues are specific, and the narrative needs actual proof.
Sector filing guides
The same SEC form reads differently by industry
Sector guides help readers avoid using a generic 10-K or 10-Q checklist when the real proof points are industry-specific.

Why this shelf exists
Many readers do not need more market commentary. They need a calmer way to understand the filing, a practical way to test the narrative, and a repeatable path back into the source. That is the gap this hub is meant to fill.
The goal is not to turn filing research into trivia. It is to make the first read less opaque, the second read more analytical, and the next quarter easier to judge.
How to use it with the rest of the library
Read one guide until the document makes sense, then open a filing summary page or company coverage page and see how the same ideas show up in a live report. That sequence matters because the product pages become much more useful once you know what you are looking at.
The hub is organized around filing basics, investor workflows, case studies, red-flag review, signal libraries, and mental models. It is meant to stand on its own even before you use the search tool.
