These are 3 Buying Principles principles distilled from George Soros's writing and public remarks. Use them as a decision checkpoint: translate each rule into a yes/no test, write what evidence would change your mind, and set a review date before you act. When a rule feels vague, open the full principle page and capture the driver you can verify (cash flows, leverage, incentives, competitive edge). This is educational, not investment advice—double-check primary sources and fit every rule to your time horizon, risk budget, and constraints.

"The cardinal rule of investing: buy only when the price is significantly below your conservative estimate of intrinsic value. This builds in protection against error."
