Ray Dalio Bio
Raymond Thomas Dalio (born August 8, 1949) is an American billionaire investor and the founder of Bridgewater Associates, one of the world’s largest hedge funds. Born and raised in New York City, he built Bridgewater into a leading global macro investment firm and popularized investment approaches such as risk parity. He is the author of Principles: Life & Work and several other books on economics and management. As of February 2026, his net worth was estimated at $20 billion.
Early Life and Background
Raymond Thomas Dalio was born in the Jackson Heights neighborhood of Queens in New York City. He is the son of Marino Dallolio (1911–2002), an Italian-American jazz musician, and Ann, a homemaker. When he was eight years old, his family moved from Jackson Heights to Manhasset in Nassau County, Long Island.
He attended Herricks High School on Long Island and went on to earn a Bachelor of Science degree in Finance from C.W. Post College of Long Island University. After finishing his undergraduate studies, Dalio worked as a clerk on the New York Stock Exchange, where he gained his earliest exposure to the financial markets.
He later received an MBA from Harvard Business School in 1973. During his time at Harvard, Dalio and his classmates created a small company that traded commodities. Although that early venture produced little profit, it planted the seed for what would later become Bridgewater Associates.
Path to Hedge Fund Founder
After graduating from Harvard, Dalio moved to Wilton, Connecticut, and began trading commodity futures out of a converted barn. He worked on the floor of the New York Stock Exchange and later served as Director of Commodities at Dominick & Dominick LLC. In 1974, he became a futures trader and broker at the securities firm Shearson Hayden Stone, where he advised cattle ranchers, grain producers, and other farmers on how to hedge risks using futures contracts. Dalio was fired from Shearson Hayden Stone after punching his boss in the face while drunk at a New Year’s Eve party in 1974.
Despite the setback, Dalio used the experience to launch his own firm. In 1975, he founded Bridgewater Associates, initially operating it as a wealth advisory firm serving corporate clients he had met at Shearson Hayden Stone. The company began publishing a paid subscription research report, Daily Observations, which analyzed global market trends and helped establish Bridgewater’s reputation on Wall Street.
Ray Dalio Career
Early Career (1974–1980)
Raymond Thomas Dalio’s first significant Wall Street role came in 1974 at Shearson Hayden Stone, where he focused on commodity futures and risk hedging for agricultural clients. His break with the firm came at the end of that same year, after the New Year’s Eve incident that led to his dismissal.
In 1975, Dalio founded Bridgewater Associates in New York as a small advisory business. Early clients included McDonald’s, followed by larger institutional accounts such as the pension funds for the World Bank and Eastman Kodak. The firm opened an office in Westport, Connecticut in 1981, where Dalio and his wife started their family.
Bridgewater Breakthrough (1981–2004)
Dalio began to attract wider attention after turning a profit during the 1987 stock market crash. In 1991, he launched Bridgewater’s flagship strategy, Pure Alpha, designed to generate excess returns adjusted for risk. Five years later, in 1996, Dalio introduced the All Weather fund, a low-risk strategy built on the risk parity approach that he helped popularize across the industry.
Through the 1990s and early 2000s, Bridgewater grew steadily by serving institutional clients with research-driven global macro strategies. The firm focused on currency and fixed income markets, using its risk parity framework to manage diversification across economic environments.
Global Macro Era (2005–Present)
Bridgewater Associates became the world’s largest hedge fund in 2005, cementing Dalio’s standing at the top of the industry. In 2007, the firm predicted the 2008 financial crisis, and in 2008 Dalio published How the Economic Machine Works, an essay assessing the potential of various economies.
From 2011 onward, Dalio expanded his influence beyond investing. He self-published a 123-page volume titled Principles in 2011, then released the expanded New York Times bestseller Principles: Life & Work in 2017, followed by Principles for Success in 2019 and Principles for Navigating Big Debt Crises in 2018. In 2021, he published Principles for Dealing with the Changing World Order, and in 2025 he released How Countries Go Broke: The Big Cycle, which became a New York Times bestseller. Dalio served as co-CEO of Bridgewater for ten months before stepping down in April 2017, and he sold his last shares in the hedge fund in 2025.
Notable Events and Milestones
Among Dalio’s signature achievements, Bridgewater’s successful bet against the subprime mortgage market in 2007 and 2008 demonstrated the firm’s research-driven model to the wider world. He was named to the Time 100 list of the most influential people in 2012 and was ranked No. 2 on Institutional Investor’s Alpha 2012 Rich List. Dalio was also among Bloomberg Markets’ 50 Most Influential people in 2011 and 2012.

Career Highlights

The firm’s later prediction of the 2008 financial crisis and its strong performance during that downturn cemented Dalio’s reputation as one of the most influential investors of his generation.
More recently, Dalio’s growing library of bestsellers, including Principles: Life & Work and How Countries Go Broke: The Big Cycle, has extended his influence from finance into economics, management, and public policy.
