The Library Essay
An Investor Shows His Working
Ray Dalio founded Bridgewater Associates from his apartment in 1975 and built it into the largest hedge fund in the world, and his explanation for that outcome is the subject of this book: not brilliance but written rules, several hundred of them, refined over decades and applied to everything from hiring to market analysis. Errors, in his system, exist to be recorded, diagnosed and converted into principles, so the firm compounds judgement the way portfolios compound money.
Published in 2017, Principles became an immediate bestseller and made Bridgewater's internal culture of radical transparency, with its taped meetings and public disagreement, a subject of general fascination. Readers need not adopt the whole apparatus; the book's durable claim is narrower, that an examined process beats an unexamined talent.
