Stock Thesis Checker
Check a stock thesis against dated public evidence, source-linked claims, a forced bear case, and missing-evidence flags.
I have a stock thesis and want to know whether public evidence supports it, contradicts it, or leaves important proof missing.
A stock thesis checker tests your company thesis against public evidence. You enter a ticker and thesis; ThesisCheck returns sourced support, a forced bear case, and missing-evidence flags without giving investment advice.
What is a stock thesis checker?
A stock thesis checker helps you test whether an investment thesis is supported by public evidence, contradicted by filings, or missing proof. ThesisCheck is built for investors who already have a thesis and want a source-linked review.
- Ticker and thesis in.
- Dated evidence and source-linked claims out.
- Support, contradiction, context, and missing evidence separated instead of blended into a generic summary.
How a thesis check works
The public workflow can be explained without revealing internal prompts, scoring, retrieval rules, or model routing.
Start with a company and the claim you actually want tested.
The review separates the story into evidence-bearing claims instead of writing one blended paragraph.
Material claims are tied to source label, date, and locator where public evidence is shown.
The output looks for facts that weaken the thesis and marks what could not be proven.
Example input and output
Microsoft's AI and cloud investments can keep Azure growth compounding without breaking margins.
Azure and other cloud services revenue was still growing quickly in FY2025.
Evidence summary: The annual report reports 34% growth for Azure and other cloud services revenue, driven by consumption-based services.
The growth claim has direct source support, but the broader margin thesis still needs separate checks for capital intensity and return on AI infrastructure spend.
Manual filing review vs structured thesis check
You decide which filings and sections to inspect.
The workflow starts from the thesis and asks what evidence would prove or weaken it.
Notes, highlights, and judgment calls spread across documents.
A source-linked ledger of supported, bear-case, and missing-evidence findings.
Easy to miss a buried contradiction or over-weight a headline metric.
Contradictions and missing proof are promoted into the review instead of hidden.
