How to Write a Checkable Stock Thesis

Write a stock thesis that can be tested against public evidence, bear-case findings, and missing-evidence gaps.

The question

I have a company view, but I need to turn it into a thesis that a source-backed review can actually test.

What this answers

A checkable thesis names the belief, the reason, the evidence that should exist, the risk that would weaken it, and the timeframe or catalyst that matters.

Definition

A checkable thesis makes evidence expectations explicit

A broad opinion is hard to test. A checkable thesis says what you believe, why it should be true, what public evidence should support it, and what would weaken it.

  • Name the company-specific claim.
  • State the reason the claim should be true.
  • Name the evidence or disclosure you expect to find.
  • Include the risk, milestone, or timeframe that matters.
Thesis helper

Use five prompts before running a check

The in-app thesis helper follows the same pattern so the report has a concrete claim to test.

01
Belief

What do you believe about the company?

02
Reason

Why should that belief be true?

03
Expected evidence

What filings, disclosures, or source-backed facts should support it?

04
Disconfirming evidence

What would weaken or break the thesis?

05
Timeframe

Which milestone, filing cycle, or catalyst matters?

Example

From broad opinion to checkable thesis

Input thesis

OKLO is a good company.

Checked claim

OKLO can commercialize Aurora faster than expected because disclosures should show site access, customer commitments, fuel supply progress, and regulatory milestones.
