About ThesisCheck
ThesisCheck is a tool that evaluates a written stock thesis by comparing its claims against a company’s public filings. Users input a ticker, its market, and their thesis as written. The tool then breaks the thesis into material claims and tallies each one as supported by the filings, contradicted by the filings, or not found in any reviewed document. Each finding is linked to dated evidence from sources such as 10-K, 10-Q, 8-K, proxy, ownership, 20-F, 40-F, and 6-K filings. The output is a public ledger that records supporting evidence, pressures to the thesis, and unresolved gaps, allowing investors to audit the reasoning behind each conclusion. The service covers filings from SEC EDGAR, ASX, LSE, and Japan’s EDINET, but excludes funds, ETFs, and derivative instruments. Reports are structured to highlight gaps rather than conceal them, providing a counterargument derived directly from disclosed information.

Frequently asked questions about ThesisCheck
What is ThesisCheck?
ThesisCheck is a source-backed thesis pressure test designed for self-directed investors to evaluate written stock theses against public company filings. It returns a dated evidence ledger that separates supporting evidence, disconfirming findings, and unresolved gaps, with each material claim linked to a source.
What does a ThesisCheck report actually find?
A ThesisCheck report provides a dated evidence ledger that categorizes each material claim in a thesis as supported by filings, contradicted by filings, or not found in any reviewed document. Each finding is linked to dated evidence from sources such as 10-K, 10-Q, 8-K, and other filings.
Who is ThesisCheck for, and who is it not for?
ThesisCheck is best suited for individual listed companies where the user has a written thesis with concrete claims and seeks a mandatory counterargument from public filings. It is not designed for valuation modeling, live market data, portfolio decisions, funds, ETFs, or information that is not publicly disclosed.
Does ThesisCheck show what it could not confirm?
Yes, claims that the reviewed sources do not establish are flagged as unresolved gaps in the report, and these remain visible rather than being concealed behind a rating.
Which exchanges and filings does ThesisCheck cover?
Coverage spans SEC EDGAR, ASX, LSE, and Japan's EDINET, including filings such as 10-K, 10-Q, 8-K, proxy, ownership, 20-F, 40-F, and 6-K where applicable. Funds and ETFs are excluded from coverage.
What pricing models does ThesisCheck offer?
ThesisCheck offers pay-per-check pricing, a pack of checks for a project, or a monthly subscription with credits for routine research. Pricing options include individual checks, packs of three checks, or a subscription with a lower effective price per check.
