Yield Theory

Yield Theory is an independent investment research publication for retail investors who manage their own money and want to understand the businesses behind their investments. It focuses on the evidence behind a view and says no finance background is needed. It presents itself as research and education, not a broker or a source of personalized advice, and it does not guarantee returns.

Free resources include research articles, stock pages, a tracker of US congressional trade disclosures, 34 source-linked investing calculators and downloadable CSV and JSON datasets, such as congressional disclosures and Big Tech AI capital spending. Members receive monthly research files with investment cases, models and valuations, catalysts and risks, sources and open questions, plus a 24-chapter fundamental research course of about five hours with interactive explainers and practice exercises.

Membership costs $39 per month or $249 per year, billed through Whop. Renewals can be cancelled from the account at any time, with access continuing until the end of the paid period. Congressional trade data is delayed and reported in value ranges, and the site is funded by memberships rather than display advertising.
