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.

Seth Klarman

Klarman is the most orthodox value investor of his generation. Pure Graham and Dodd — buy things for significantly less than they''re worth, insist on a large margin of safety, and be patient.

Very patient. He specifically hunts for things that other investors have been forced to sell for non-fundamental reasons: bankruptcies, spin-offs, index fund rebalancings, distressed situations where complexity drives away everyone else.

His book Margin of Safety was published in 1991 in an edition of 5,000 copies, went out of print, and now sells for over $1,000 on the secondary market. Harvard Business School uses it as a course text.

Digital copies circulate informally online. The irony of a book about value investing being itself severely mispriced is not lost on anyone who reads it.

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.

Seth Klarman

Three rules he returns to constantly. First: always insist on a margin of safety.

The future is uncertain. If you only buy things that look cheap under pessimistic assumptions, you protect yourself from your own mistakes.

Second: be a long-term owner, not a short-term trader. Price converges to value over time — not tomorrow.

Third: hold cash when you can''t find good opportunities. Cash is not idle.

Cash is optionality — it means you can act decisively when panic creates real bargains.

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.

Seth Klarman

He is the most conservative major hedge fund manager operating today. He has said publicly he would rather earn 6% sitting in cash than take a risk he doesn''t understand.

His view of risk is Graham''s view: the probability of permanent loss of capital. Volatility doesn''t scare him.

Permanent loss does.

He''s also been an outspoken critic of short-term trading culture that treats markets as price-discovery engines rather than ownership stakes in real businesses. He sees most of what passes for investing as speculation dressed up in confident language.

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.

Seth Klarman

He lives in the Boston area. He''s a significant political and philanthropic donor — primarily to causes related to Israel, Holocaust education, and academic institutions.

He''s reportedly deeply private, compartmentalising his professional and personal lives completely. He is, by multiple accounts, obsessive about physical fitness.

He does not seek press coverage and actively avoids it.

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.

Seth Klarman

His 40-year sustained performance is the win. There''s no single flashy trade that defined his career — which is itself kind of the point.

During the 2008 financial crisis, Baupost deployed significant capital into distressed mortgage securities and bank debt, buying things that were trading at catastrophic discounts because forced sellers had to liquidate. The returns on those positions were exceptional.

He was ready because he''d been holding cash waiting for exactly this type of opportunity.

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.

Seth Klarman

By his own account, his biggest mistakes have been not buying enough when he was confident. He''s written about passing on things he understood and believed in because he was waiting for a slightly better price that never came.

The classic value investor error of omission.

He''s also been early — and expensive — on some macro concerns. He has been warning about Federal Reserve policy and deficit spending for over a decade.

He''s probably right about the underlying risks. The timing has cost him relative returns.

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.

Seth Klarman

Seth Klarman grew up in Baltimore, Maryland. He studied economics at Cornell, then got his MBA from Harvard Business School in 1982.

He went straight from Harvard to work for Max Heine and Michael Price at Mutual Series Fund — two of the best value investors of that era. After two years he co-founded Baupost Group in 1983 with $27 million from four Harvard endowment families.

He was 25. He has been running it ever since.

Baupost is based in Boston and has consistently avoided the publicity-seeking behaviour of most large hedge funds. Klarman doesn''t do television.

He doesn''t do conferences. He gives very few interviews.

His annual letters to investors circulate informally because investors share them despite the confidentiality agreements. He has been compared to Warren Buffett more than almost any other living investor — in both style and the quality of his thinking.

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.

Seth Klarman

Baupost Group is the whole story. Founded in 1983 with $27 million, it now manages around $30 billion.

The fund focuses on distressed securities, special situations, bankruptcies, and assets where other investors can''t or won''t participate — either because of regulatory constraints, illiquidity, or sheer complexity.

He''s famously kept 30–50% of the portfolio in cash during periods when he can''t find attractively priced opportunities. Most fund managers feel pressure to be fully invested at all times.

Klarman has explicitly said that holding cash is an active decision — not a failure to deploy, but a choice to wait for real value.

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.

Seth Klarman

Cornell University, BA in Economics, 1979. Harvard Business School, MBA, 1982.

Went straight from Harvard to join Max Heine and Michael Price at Mutual Series Fund — two of the most important value investors of that generation. That two-year apprenticeship shaped everything.
