Ray Dalio, founder of Bridgewater Associates, participated in the “Talks at Google” series in 2018, sharing his principles for investing and life. The Q&A session following Ray’s talk was moderated by Jordan Thibodeau.

Ray founded Bridgewater in 1975 in his two-bedroom apartment in New York. Forty years later, Bridgewater has made more money for its clients than any other hedge fund in history.

In his book, Principles, Ray shares what he has learned over his remarkable career, arguing that life, management, economics, and investing can be systemized into rules. The book’s practical lessons, built around his cornerstones of “radical truth” and “radical transparency,” offers a clear approach to decision-making.
