Ray Dalio

Dalio thinks in cycles — economic cycles, debt cycles, historical cycles that repeat over decades and centuries. His core belief: everything in markets has happened before.

Study history deeply enough and you can anticipate what comes next. He called the long-term decline of US dollar dominance a slow, inevitable process — not a crisis tomorrow, but not permanent either.

His All Weather approach is built for radical uncertainty. Instead of predicting what will happen, build a portfolio that does okay no matter what.

Stocks, bonds, gold, and commodities tend to move in different directions across different economic environments. Own a smart mix and you're never completely wrong.

Paul Tudor Jones

Jones is a global macro trader with a strong technical overlay. He looks for major macro trends — interest rate cycles, currency moves, commodity supercycles — and positions for them using futures and options across multiple asset classes.

He is also heavily influenced by technical analysis: he uses Elliott Wave theory and studies historical market patterns to time entries and exits. He is not a value investor in any sense.

He does not care much what a company is fundamentally worth. He cares about momentum, sentiment, and positioning.

Ray Dalio

His most important principle: pain plus reflection equals progress. He applied this to investing, management, and life.

Most people's biggest problem is they avoid pain instead of learning from it. His second idea: diversification is the holy grail of investing.

Not 15 correlated stocks — real diversification across asset classes, geographies, and economic environments that actually move differently. Third: everything is a machine.

Markets, economies, relationships — they all operate by rules that can be understood if you study them. He documented all his rules in a book called Principles.

Whether or not you agree with him, very few investors have been this explicit about writing everything down.

Paul Tudor Jones

Jones believes that markets move in cycles and that those cycles have technical signatures that repeat because human behavior repeats. He has said that the most important thing in trading is not being right — it is losing the minimum amount when you are wrong.

His 5:1 risk/reward rule — only take a trade if you think you can make five times what you risk — is widely cited. He is also a believer in global macro as the purest expression of investment thinking: you are betting on the direction of entire economies, not individual companies.

Ray Dalio

He hates overconfidence in any single bet. The 1982 disaster cured him of that.

His solution: systematically stress-test every idea. Hire people to argue against you.

Find the best counterargument to your own position, then decide. He called this "believability-weighted decision making" — the person who has been right more often on a specific topic gets more weight in any disagreement.

At Bridgewater, this became formalized into actual systems and algorithms. His personal risk profile is moderate.

He doesn't use excessive leverage, and All Weather is explicitly designed to reduce volatility rather than maximize return.

Paul Tudor Jones

Jones is famous for a single risk management rule: never risk more than 1% of your portfolio on any one trade. He has described this as the most important rule in trading.

The mathematical implication is that you need to be catastrophically wrong many times in a row before the fund is seriously damaged. He also cuts losing positions immediately.

He has said that he would rather miss a move than hold a losing position. The 1987 short was the exception that proved the rule — he sized it heavily because his conviction was unusually high.

Ray Dalio

He lives in Westport, Connecticut. He practices transcendental meditation daily and says it's one of the most important habits in his life.

He runs and practices yoga. He and his wife Barbara pledged to give away more than half their wealth through the Dalio Philanthropies, focusing on ocean conservation, education reform in Connecticut, and mental health research.

He posts long essays on LinkedIn about global macro trends — which is either a public service or unsolicited geopolitical commentary, depending on how you feel about him.

Paul Tudor Jones

Jones lives primarily in Greenwich, Connecticut and Palm Beach. He is a serious conservationist and owns significant land in Tanzania, where he runs conservation programs.

He founded the Robin Hood Foundation in 1988, which has raised over $4 billion to fight poverty in New York City. He is a major donor to the University of Virginia, where a building bears his name.

He does not live extravagantly by hedge fund standards — his philanthropy is where the money goes.

Ray Dalio

2008. While most hedge funds were losing 20 to 30 percent, Bridgewater's Pure Alpha fund returned +9.5% and the All Weather fund was roughly flat.

This wasn't luck. Dalio had been warning about the debt bubble for years.

Clients who followed his framework avoided the worst of it. By 2010, Bridgewater managed $80 billion.

The win wasn't a single trade — it was being structurally right about the entire environment when almost everyone else was wrong.

Paul Tudor Jones

The 1987 Black Monday trade defines his career. Jones had studied historical market patterns and become convinced that the US stock market was behaving similarly to 1929.

He shorted the market aggressively through futures. On October 19, 1987, the Dow Jones fell 22.6% in a single session.

Tudor's BVI Global Fund returned approximately 200% for the year. He personally made around $100 million.

The trade was captured in a PBS documentary called "Trader" filmed earlier that year — footage that shows him predicting the crash almost to the day. He later asked for the documentary to be suppressed, believing it gave away too much about how he thought.

That request made it more famous.

Ray Dalio

1982. He predicted a depression caused by Mexico's debt default.

He was wrong. He lost his own money, had to lay off all his staff, and borrowed $4,000 from his father.

He's talked about it publicly as the most formative experience of his life. The lesson he drew: strong conviction without aggressive stress-testing is just expensive confidence.

He also admitted later that his radical transparency culture at Bridgewater went too far in some ways. Recording every conversation and requiring every decision to be challenged in real time worked as a philosophy.

As a daily workplace experience, multiple lawsuits and employee complaints suggested it could become oppressive rather than honest.

Paul Tudor Jones

The 2000s were difficult. Tudor's returns declined significantly as macro trends became less clean and trading became more crowded with quantitative competitors.

The fund has returned roughly 3% annualized in the 2010s — a steep drop from its historical average. Jones has attributed this partly to central bank distortion of markets and partly to the structural changes in how macro trends develop when central banks intervene constantly.

He has been relatively candid that the macro environment of the last decade has been his least productive.

Ray Dalio

Ray Dalio grew up in a middle-class family in Jackson Heights, Queens. At 12, he bought shares in Northeast Airlines for $300 using money earned caddying.

The airline was taken over shortly after and his shares tripled. That was the moment.

He studied finance at Long Island University, got an MBA from Harvard Business School in 1973, then worked at Merrill Lynch and a commodities firm. In 1975 he started Bridgewater Associates out of a two-bedroom New York apartment.

Just him and a phone. By the late 1980s Bridgewater was advising pension funds, sovereign wealth funds, and central banks.

By 2012 it was the largest hedge fund in the world.

The 1982 disaster shaped everything. Dalio publicly predicted a depression triggered by Mexico's debt default.

He was wrong. He lost so much that he laid off his entire staff and borrowed $4,000 from his father to cover expenses.

He rebuilt completely from that near-failure. The experience taught him that strong conviction without aggressive stress-testing is just expensive confidence.

Paul Tudor Jones

Jones grew up in Memphis, Tennessee, in a comfortable family and attended the University of Virginia, where he studied economics. After graduating in 1976 he cold-called commodity trader Eli Tullis in New Orleans, worked for him briefly, then moved to New York and got a job as a commodities broker at E.F.

Hutton. He was a natural.

By 1980 he had connected with cotton trader William Dunavant, one of the largest cotton merchants in the world, who gave him capital to trade.

In 1980 he founded Tudor Investment Corporation with a small amount of seed money. The early years were cotton and commodities — he was a floor trader turned fund manager.

Then came the macro: he began studying market cycles, Elliott Wave theory, and the technical patterns that preceded major market crashes. By October 1987, he was positioned short.

The Dow fell 22.6% on October 19, 1987 — still the largest single-day percentage decline in US stock market history. Tudor's fund tripled that year.

Ray Dalio

Bridgewater Associates is the whole story. He founded it in 1975, built it to $150 billion in assets under management, and stepped back from day-to-day management in 2017 before stepping down as co-CEO in 2022.

The fund runs two main strategies. Pure Alpha seeks to outperform markets through active macro bets.

All Weather is designed to perform adequately in any economic environment — regardless of whether growth is rising or falling, inflation is high or low. The All Weather approach has been widely copied under the name "risk parity." He has also invested personally in various companies and become a prominent voice on global debt cycles and geopolitics.

Paul Tudor Jones

Tudor Investment Corp, founded in 1980, is his flagship firm managing approximately $12 billion. It runs global macro strategies across equities, fixed income, currencies, and commodities.

The fund has averaged approximately 19% annual net returns since inception — extraordinary over four decades — though returns in recent years have been more modest as macro trading has become more crowded and central bank intervention has made trends harder to read.

He also founded Just Capital, a nonprofit that ranks American corporations on their treatment of workers, communities, and the environment — and has made this work a second career alongside trading. He sits on the boards of multiple institutions and is a substantial donor to education and conservation causes.

Ray Dalio

BA from C.W. Post College (now Long Island University), 1971.

MBA from Harvard Business School, 1973. He's talked about not being a great student — he got into Harvard on determination and test scores rather than academic polish.

Paul Tudor Jones

University of Virginia, BA in Economics, 1976. He has donated extensively to UVA — the Paul Tudor Jones Commons is named in his honor.

He has also credited his early mentor Eli Tullis as more formative than any formal education — Tullis taught him discipline and the emotional demands of trading.
