Ray Dalio was born in 1949 in Jackson Heights, Queens, to homemaker Anne and jazz musician Marino, and grew up on Long Island. After a finance degree from C.W. Post College and a clerk job on the New York Stock Exchange floor, he earned a Harvard MBA in 1973. At Shearson Hayden Stone he advised cattle ranchers and grain producers on hedging with futures, until he was fired for punching his boss at a New Year's Eve party in 1974. In 1975 he founded Bridgewater Associates, trading out of a converted barn in Wilton, Connecticut, and wrote the Daily Observations research report. McDonald's signed on, followed by the World Bank and Eastman Kodak pension funds.

Bridgewater launched Pure Alpha in 1991 and the All Weather Fund in 1996, pioneering risk parity, and became the world's largest hedge fund by 2005. Dalio predicted the 2008 crisis in 2007 and coined the D-process for deleveraging. His Principles, self-published in 2011 and a number one bestseller in 2017, codified radical transparency, with meetings recorded and staff rating each other on iPads. In 2023 the New York Times and Rob Copeland's book The Fund reported that returns came largely from Dalio's own instincts and that the culture bred paranoia; Dalio called the book fiction. He sold his last shares in 2025.
