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.

Scott Galloway

Galloway's personal investing style is relatively conservative given how loud he is. He keeps a heavy allocation in index funds and real estate.

He does make concentrated bets on individual stocks when he has conviction — he famously held Amazon for years. He angel invests occasionally but is not prolific.

His real wealth comes from business exits and media income, not portfolio management.

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.

Scott Galloway

Diversify, own assets, and do not confuse being smart with being lucky. Galloway preaches that the most reliable path to wealth is boring — buy index funds, own property in growing cities, and let time do the work.

He is deeply skeptical of anyone who claims they can consistently beat the market.

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.

Scott Galloway

Moderate. Galloway has experienced the full spectrum — he had a company go public and then go bankrupt (Red Envelope), which taught him that financial ruin is always closer than you think.

Post-L2 sale, he became much more conservative. Heavy real estate holdings in New York and Florida.

He preaches diversification publicly and mostly follows his own advice, with occasional concentrated stock positions.

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.

Scott Galloway

Galloway owns significant real estate in New York and Florida. He talks openly about his wealth and spending — nice apartments, good restaurants, private school for his kids.

He is not frugal and does not pretend to be. But he is very intentional about where money goes.

He has said his biggest financial luxury is "buying back his time" — paying for convenience so he can focus on what matters.

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.

Scott Galloway

Selling L2 to Gartner for an estimated $134 million in 2017. He built L2 into the go-to benchmarking firm for digital competence of luxury and consumer brands.

The exit, combined with his media career taking off simultaneously, catapulted him from "NYU professor" to "famous rich guy who yells about tech on the internet."

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.

Scott Galloway

Red Envelope. Full stop.

Galloway has been brutally honest about this — he took a gift e-commerce company public, it was valued at hundreds of millions, and then it went bankrupt. He has called it the most painful experience of his career and has said it took years to emotionally recover.

He lost a significant amount of personal wealth in the collapse.

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.

Scott Galloway

Scott Galloway is a serial entrepreneur and NYU Stern School of Business professor who became famous for his brutally honest takes on Big Tech. He founded nine companies over his career, including L2 (a business intelligence firm sold to Gartner in 2017), Red Envelope (an e-commerce company that went public then bankrupt), and Prophet (a brand strategy firm).

His 2017 book The Four, about Amazon, Apple, Facebook, and Google, became a bestseller. His YouTube channel and Prof G podcast reach millions.

He called Amazon buying Whole Foods before it happened. He also co-hosts Pivot with Kara Swisher, one of the most popular tech podcasts in the world.

He teaches brand strategy at NYU and is known for his profanity-laced, data-heavy lectures that go viral every semester.

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.
