Stock Research Source Hierarchy Checklist

Stock research gets sloppy when every source feels equal. A primary filing, an earnings-call transcript, a sell-side headline, a social thread, and a price chart can all matter, but they do not deserve the same weight. A source hierarchy gives each input a job so the thesis does not become a pile of screenshots. This page is educational and process-focused. It does not tell you what to trade, what to buy, or which account choice fits your life. The goal is to make the research, math, and review process cleaner.

The simple concept

A source hierarchy is a ranking system for evidence. Primary company documents sit near the top. Market data, transcript notes, and reputable third-party datasets can support the work. Rumors, social posts, and hot takes sit near the bottom until they are verified against stronger records.

For Bucko readers, the better question is not, "What is the hot answer?" It is, "Can I explain the evidence, write the assumptions, measure the friction, and review the decision without changing the story later?"

The math that matters

Example: give each claim a confidence score from 1 to 5. A revenue-growth claim pulled directly from a filing might score 5. A management quote from a call might score 4 because it is useful but still needs numbers. A social post saying demand is exploding might score 1 or 2 until you can tie it to orders, margins, backlog, or other source records. If a thesis has ten claims and seven are low-confidence, the thesis is not ready for serious sizing or conviction.

The exact numbers will vary by source, broker, account, tax situation, fund document, liquidity, and market conditions. The durable habit is simple: write the number, write the source, and write what would make the note stale.

Practical checklist

• ▸Separate primary sources, company commentary, third-party data, news, and opinion before writing the thesis.
• ▸Attach every major claim to a source tier and a date checked.
• ▸Use filings and company records for historical numbers; use calls and decks for context, not automatic proof.
• ▸Mark estimates, projections, rumors, and social narratives as unverified until stronger evidence appears.
• ▸Write what would change your view before the next earnings report or company update.

A decision framework

Score the idea from 1 to 5 on four dimensions:

• ▸Evidence: are the key claims tied to current source records?
• ▸Math: have costs, risk, sizing, or exposure been turned into numbers?
• ▸Fit: does the decision match the written plan instead of the mood of the day?
• ▸Review: will the notes show what changed after new information arrived?

A low score does not mean the idea is useless. It means the process needs a cleaner source, smaller scope, or more review before the decision gets emotional.

Common mistakes

• ▸Treating a clean chart as proof that the business is improving.
• ▸Quoting management commentary without checking whether the numbers support it.
• ▸Letting social-media confidence replace source quality.
• ▸Updating the thesis only when price moves, instead of when the evidence changes.

How Bucko fits

Bucko works best as an educational research, journaling, scenario-analysis, and guardrail workspace. Use it to save assumptions, tag sources, compare scenarios, and review the process after the outcome is known. The tool should make your workflow easier to inspect; it should not take responsibility away from you.
