Stock backtesting: how to test investment ideas
Learn how to define a testable strategy, select an appropriate benchmark, account for costs and drawdowns, and recognize survivorship and look-ahead bias.
ThetaBrew publishes practical educational resources for investors who want to evaluate market ideas with clearer evidence and context. These guides explain research methods, the assumptions behind common analyses, and the limits that matter when using historical or public data.
Our goal is to make the research process easier to inspect: define a question, identify the data available at the time, compare alternatives, and look for the risks that a headline result can hide. The material is for education and general research only; it is not personalized investment, tax, or legal advice.
