Michael Burry

Burry is a pure fundamental analyst. He reads the actual documents.

Not the analyst summary. Not the ratings agency report.

The actual prospectus, the loan files, the footnotes. For the Big Short trade, he read thousands of individual mortgage loan documents.

Nobody else was doing that. Analysts were looking at aggregate statistics.

The aggregate statistics looked fine. The individual loans were a disaster.

His basic method: find something everyone is ignoring, do the work to understand why it''s mispriced, take a position, and wait. The waiting is the hard part.

He was short the housing market for two years before it collapsed. During those two years his investors were losing money on paper and threatening legal action.

He locked redemptions to prevent forced liquidation. He was right and it cost him two years of misery to prove it.

Charlie Munger

Munger's whole thing is mental models. The idea is simple: instead of being an expert in one field, you learn the core concepts from as many different fields as possible — psychology, biology, physics, economics, history — and then use that whole toolkit to think about problems.

He calls it a latticework of mental models. It sounds like a self-help concept.

It's actually how he consistently made better decisions than almost everyone around him. On investing, he pushed Buffett away from his old mentor's approach — which was basically "find dirt-cheap companies and flip them fast" — toward something more durable: find the best businesses in the world and hold them forever.

The key word he uses is moat. A business so dominant that competitors can't touch it.

Think Coca-Cola. He was also deeply influenced by psychology, particularly the ways humans reliably fool themselves.

He gave a famous talk called "The Psychology of Human Misjudgment" listing 25 ways our brains get things wrong. Reading it once will change how you make decisions.

Michael Burry

Read the documents. That is basically the whole philosophy.

Not the summary. Not the analyst report.

The actual documents. Most investors don''t do this because it''s tedious and slow and it requires a tolerance for complexity that most people don''t want to develop.

His second rule: be willing to be lonely. His housing short was a deeply contrarian position that most finance professionals thought was ridiculous.

He didn''t need their validation. He needed the math to work.

His third: factor in time when sizing a position. The housing market stayed wrong for two years.

Size your position so you can survive being right too early.

Charlie Munger

Invert. Always invert.

That's his most famous rule — borrowed from the mathematician Jacobi. Instead of asking "how do I succeed?" ask "what would guarantee failure, and then avoid those things." It sounds obvious.

Almost nobody actually does it. He believes the secret to a good life and good investing is the same: figure out what you want to avoid, avoid it relentlessly, and most good things follow.

On wealth: getting rich isn't the hard part — keeping it is. Most people blow up by using borrowed money, getting greedy at the top, or panicking at the bottom.

Don't do those things. On decisions: only make the big bet when you're very sure.

Be patient for a long time, then move fast when the opportunity is obvious.

Michael Burry

He concentrates heavily. When he has a thesis, he puts a large portion of the fund into it.

He also used leverage on the housing trade — borrowing to buy credit default swaps amplified both the wait and the eventual payoff. His risk tolerance is high in the sense that he can hold a losing position for years if the fundamental analysis is intact.

It is low in the sense that he won''t touch anything he doesn''t deeply understand. He doesn''t trade momentum or narratives.

If the math doesn''t work, he''s not interested.

Charlie Munger

Munger's approach to risk: don't take risks you don't understand, and don't take risks you don't need to. He kept things simple.

He concentrated into a small number of businesses he understood deeply. He never used borrowed money.

He kept large cash reserves. His view on diversification was almost the opposite of what most financial advisors tell you — he thought spreading money across 50 stocks was an admission that you hadn't done enough homework.

If you've done the work, you concentrate. If you haven't, maybe don't invest at all.

Michael Burry

He lives in Saratoga, California. He is notoriously private — he has opened and deleted social media accounts multiple times after his market commentary attracted more attention than he wanted.

He occasionally posts about market risks and then goes quiet for months. He has a son with Asperger''s syndrome, and the experience led him to recognise similar traits in himself and pursue his own autism diagnosis as an adult.

He doesn''t do conferences. He doesn''t do interviews.

He files his quarterly 13F and lets the positions speak.

Charlie Munger

Munger lived in the same house in Los Angeles for most of his adult life. He was famously frugal — not in a miserable way, but in a "I genuinely don't care about most things money buys" way.

He flew commercial until fairly recently. He read obsessively.

He described himself as a book with legs. His children joked that he was more interesting to talk to than almost anyone alive, but would only engage on topics he found intellectually stimulating.

He donated massively to education — hundreds of millions to Harvard Law School, the University of Michigan, and other institutions, often with very specific conditions attached. He designed buildings as a hobby and funded their construction himself.

He died at 99 worth around $2.6 billion — extraordinary by any measure, and somehow modest given he sat next to one of the richest men in history for 45 years.

Michael Burry

The housing trade. In 2005, Burry read thousands of subprime mortgage loan documents and concluded the US housing market was built on loans that would eventually default in large numbers.

He persuaded Goldman Sachs and Deutsche Bank to sell him credit default swaps on mortgage-backed securities — essentially insurance that paid out when the mortgages defaulted. The banks thought he was wrong.

They were happy to take his premiums. In 2007–2008 the mortgages defaulted.

His investors made $700 million. Burry personally made about $100 million.

The banks that sold him the swaps needed government bailouts to survive.

Charlie Munger

See's Candies. In 1972, Munger convinced a reluctant Buffett to pay what seemed like an expensive price — $25 million — for a California candy company.

Buffett thought it was too much. Munger held firm.

See's has since generated over $2 billion in profit for Berkshire, basically funding dozens of other acquisitions. It also taught Buffett the single most important lesson of his career: paying a fair price for a great business beats getting a cheap price for a mediocre one.

That one deal changed the entire direction of Berkshire Hathaway.

Michael Burry

The trade nearly destroyed him before it paid off. He locked investor redemptions to prevent forced liquidation of his position — probably the right call, but it created a legal and emotional nightmare that he''s described as one of the worst periods of his life.

He also closed Scion to outside investors after winning, which in hindsight was leaving behind an institutional money management career after one of the greatest trades in history. He''s never explained that decision fully.

It may have been the right one. It may not have been.

Charlie Munger

Munger is famous for avoiding mistakes more than for making spectacular wins — his whole philosophy is about not doing stupid things. But he's admitted to a few.

He said Berkshire was too slow to move into BYD, China's electric vehicle company, despite knowing it was exceptional for years before they finally bought in. He also held too much Wesco Financial for too long when the money could have been put to better use elsewhere.

His most honest self-criticism: he wished he had moved faster when the evidence was already clear. For a man who spent his career warning others about psychological biases, he wasn't immune to them.

Michael Burry

Michael Burry was born in San Jose, California in 1971. He lost his left eye to retinoblastoma as a child and has worn a prosthetic eye since.

He studied economics at UCLA and then went to Vanderbilt University School of Medicine. During his medical residency at Stanford, he posted detailed stock analysis on investor message boards between midnight and 3 AM.

The quality was consistently good enough that people in finance started paying attention.

He left his residency in 2000 — one year from finishing — to start Scion Capital with $1.1 million in loans from his family. No finance credentials.

Just a public track record and conviction. In his first full year, the S&P 500 fell 11.9%.

Scion returned 55%. From 2001 to 2008, Scion returned over 489% against the S&P 500's 3%.

Then he made the trade.

Charlie Munger

Charlie Munger grew up in Omaha — same city as Buffett, but they didn't know each other yet. His father was a lawyer.

So was his grandfather. Charlie became one too, but he was clearly more interested in figuring out how the world worked than in courtrooms.

He studied math at the University of Michigan, got drafted into World War II, trained as a meteorologist, and somehow ended up at Harvard Law School without ever finishing an undergraduate degree. Harvard took him anyway.

He graduated in 1948 and moved to California to practice law. He was good at it.

He was also quietly building a real estate business on the side that made him more money than law ever did. He and Buffett met at a dinner in Omaha in 1959.

Munger was 35. Buffett was 28.

By the end of the night, Buffett was trying to convince Munger to go into investing full time. It took about a decade.

Munger ran his own investment partnership from 1962 to 1975 — returned 24% annually while the market did 6.4%. Then he fully merged his career with Buffett's at Berkshire, where he stayed until his death in 2023.

Michael Burry

Scion Capital ran from 2000 to 2008. He closed it to outside investors after the Big Short trade — partly because managing money for clients who were screaming at him to reverse a position he knew was right was a genuinely miserable experience, and partly because he didn't need to anymore.

He relaunched as Scion Asset Management, a personal vehicle he still runs today. His current investing is more conventional — value picks, occasional activist positions, portfolio bets that get attention when his 13F filings come out.

He bought GameStop before Reddit did. He shorted Tesla.

He has positioned in water rights and farmland. He tends to be early, which is both his gift and his problem.

Charlie Munger

Munger's main stage was Berkshire Hathaway, where he served as Vice Chairman from 1978 until he died. His role was hard to define on paper — he didn't run a fund or manage a portfolio.

What he actually did was talk to Buffett. That was worth a trillion dollars.

Before Berkshire, he ran his own investment partnership from 1962 to 1975 that crushed the market. He also controlled Wesco Financial, a small insurance and financial company he ran as a personal Berkshire subsidiary from 1973 to 2011, until Berkshire fully absorbed it.

Outside finance, he was obsessed with architecture — he personally designed several buildings, including a dormitory at the University of Michigan that his own architecture school rejected for violating design principles. He funded it anyway.

BA in Economics, UCLA. MD, Vanderbilt University School of Medicine, 1999.

He completed three years of his medical residency at Stanford before leaving to start Scion Capital. He is technically a licensed physician who never practiced.
