Warren Buffett

Buffett's approach is simple to describe and almost impossible to copy. He buys great businesses at fair prices and then just...

holds them. Forever.

He calls it "buy and hold" but that undersells it — he means hold until the sun burns out. He looks for companies with a real unfair advantage over competitors.

Something that protects them from being wiped out. He calls it a "moat" — like the water around a castle.

Think Coca-Cola. Everyone knows it.

Nobody can replicate it. He puts a LOT of money into a small number of bets — usually his top five holdings make up over 70% of everything.

Most fund managers would have a panic attack at that level of concentration. Buffett calls it being convicted.

His old mentor Graham taught him to hunt for cheap, beaten-down companies and flip them fast. Charlie Munger, his business partner for 45+ years, talked him out of that.

Munger said: just buy the best businesses you can find and never sell. Buffett admits that shift made him hundreds of billions of dollars.

Peter Lynch

Lynch invented the phrase "tenbagger" — a stock that returns ten times your money. He was specifically looking for companies that could do that.

His method was deceptively simple: invest in what you know. Not what you know about macroeconomics or interest rates — what you know about everyday life.

What stores are you shopping at? What products are your kids obsessed with?

What new thing are you using that feels like it could be everywhere in five years? If you're noticing a company before Wall Street analysts have caught on, you have a real edge.

He categorized stocks into six types: slow growers (stable, boring), stalwarts (big companies, modest returns), fast growers (small and aggressive — where the tenbaggers live), cyclicals (tied to economic cycles), turnarounds (troubled companies that might recover), and asset plays (companies with hidden value the market hasn't priced in). His genius was applying rigorous fundamental analysis to companies most Wall Street analysts dismissed as too small or too mundane to bother with.

Warren Buffett

Rule No. 1: Never lose money.

Rule No. 2: Never forget Rule No.

1. Buy businesses, not stocks — the distinction matters more than most investors realize.

Let compounding do the heavy lifting and get out of its way. Never use debt to invest.

Be fearful when others are greedy, greedy when others are fearful. Time in the market destroys timing the market in every long enough data set.

For most people, a low-cost S&P 500 index fund will outperform almost any active strategy, including most professional money managers — including, he's said, what most of his estate will go into after he's gone.

Peter Lynch

He believed the average person has a real edge over professional fund managers — specifically the access to everyday life that analysts in offices don't have. You know which stores are packed on Saturday afternoon.

You know which new products your kids are obsessed with. Wall Street analysts often don't.

His most repeated principle: invest in what you know. His second: love a company's product is not sufficient on its own — you still need to understand the fundamentals.

Third: stomach matters more than brain in investing. The biggest thing separating successful investors from unsuccessful ones isn't intelligence — it's the ability to stay calm when the market drops 20 percent and everything feels like it's ending.

Warren Buffett

Buffett's whole thing is: do so much homework that the risk basically disappears. He doesn't diversify across 500 stocks to protect himself — he researches 10 companies so deeply that he's more confident about those 10 than most people are about anything.

He never borrows money to invest. Ever.

He keeps a mountain of cash at Berkshire — over $100 billion sitting around doing nothing — specifically so he can swoop in when everyone else is panicking and selling cheap. He once called derivatives "financial weapons of mass destruction" back in 2002.

Wall Street laughed. Then 2008 happened and Wall Street stopped laughing.

He doesn't predict where the stock market is going. He predicts whether a business will still be dominant in 20 years.

That's it.

Peter Lynch

Lynch ran a very diversified portfolio — sometimes over 1,000 positions — which cuts against the concentration gospel of Buffett and Munger. He justified it simply: if you find enough genuinely great small companies, you don't need to pick just one.

Some will fail. The tenbaggers more than compensate.

He wasn't reckless — he did detailed fundamental research on every holding. But he was comfortable owning things that looked messy or unfamiliar on the surface if the numbers told a better story.

He famously said he'd rather own 20 stocks he didn't know well than five stocks he thought he knew perfectly. The point being: false confidence in a concentrated position kills you.

Breadth buys time.

Warren Buffett

Despite a $120B net worth, Buffett still lives in the same gray stucco house in Omaha he bought in 1958 for $31,500. He drives himself to work.

Breakfast is McDonald's — he orders based on his mood: $2.61, $2.95, or $3.17. He plays bridge obsessively, often online with Bill Gates.

He drinks multiple Cokes a day (Berkshire owns a large stake in Coca-Cola; coincidence is left as an exercise to the reader). He has pledged to give away more than 99% of his wealth, primarily to the Bill & Melinda Gates Foundation and his children's foundations.

He takes a $100,000 annual salary from Berkshire. He does not own a smartphone.

Peter Lynch

After retiring from Magellan in 1990, Lynch has spent most of his time on philanthropy. He and his wife Carolyn donated tens of millions to education through the Lynch Foundation, focusing on Catholic education and scholarship programs in Massachusetts.

He lives quietly for someone worth hundreds of millions. He speaks at Fidelity events occasionally, plays golf, and is generally not seeking attention.

He has said that the best decision he ever made was retiring at 46 — that no amount of money is worth missing your kids grow up.

Warren Buffett

Apple. Berkshire started buying Apple in 2016 — late by any tech investor's standard, from a man who spent decades insisting he didn't understand technology.

By 2023, the position had grown to over $170 billion, returning more than 800%. Buffett called it the best business he'd ever seen and admitted he should have bought it earlier.

Honorable mention: American Express in 1963 during the Great Salad Oil Scandal, when he put 40% of the Buffett Partnership into AmEx at distressed prices while the rest of Wall Street was running away.

Peter Lynch

Fannie Mae. Lynch bought it heavily in the mid-1980s when almost nobody wanted it.

It was a housing finance company drowning in problem mortgages. Lynch dug into the fundamentals and decided the problems were fixable and the underlying business was genuinely valuable.

He was right. The stock went from roughly $2 to $40.

That single position generated hundreds of millions for the fund. His Chrysler bet was similar — he bought heavily when the company was a bankruptcy rumor and almost no one else would touch it.

Both worked because Lynch was willing to do the research on things everyone else had already decided were too ugly to look at.

Warren Buffett

Buying Berkshire Hathaway. He bought it in 1962 as a cigar butt — a cheap, dying textile company — and then kept it instead of winding it down into a clean insurance holding company.

The C-corp structure meant decades of tax drag. He has estimated this single mistake — triggered partly by spite after the owner tried to lowball him on a buyout — cost Berkshire and its shareholders roughly $200 billion over 50 years.

He also admits missing Google and Amazon, both of which he understood well enough to buy and simply didn't.

Peter Lynch

Selling great companies too soon. He got into Walmart early and sold too soon.

He did the same with several other retailers that went on to become enormous. By his own account, his biggest mistake pattern was taking profits on genuine multi-decade compounders before they had compounded enough.

He also acknowledged that managing a $14 billion fund was fundamentally different from managing $18 million. The sheer size limited which companies he could meaningfully invest in — you can't move the needle on a $14 billion fund by buying a $50 million company.

He burned himself out keeping up with over a thousand positions. He retired at 46.

He's said he doesn't regret it.

Warren Buffett

Warren Buffett was born in Omaha, Nebraska in 1930. He bought his first stock at age 11 — three shares of a company called Cities Service.

He paid $114. He was eleven.

By 14, he owned a 40-acre farm and had filed his first tax return. He applied to Harvard Business School and got rejected.

Best thing that ever happened to him, honestly. He ended up at Columbia instead, where he met Benjamin Graham — the guy who basically invented the idea of buying undervalued stocks.

After graduating in 1951, Buffett started his own investment partnership in Omaha with $105,000 from family and friends. He turned that into something much bigger, compounding at around 30% per year for over a decade.

Then in 1969, he shut it down and quietly took over a dying Massachusetts textile company he had bought partly out of spite. That company was Berkshire Hathaway.

What happened next is the greatest investing run in history — and it started with a grudge.

Peter Lynch

Peter Lynch grew up in Newton, Massachusetts. His father died when Lynch was 10, and his mother had to work to keep the family going.

Lynch caddied at the Brae Burn Country Club to help out. One of his regular clients was D.

George Sullivan, president of Fidelity Investments. Sullivan eventually offered Lynch a summer job at Fidelity — the kind of break you earn by showing up and doing the work.

Lynch studied history, psychology, and philosophy at Boston College — not finance — and said later that was probably an advantage. Too many finance students learn to look at spreadsheets and miss the obvious things happening in front of them.

He got an MBA from the Wharton School, joined Fidelity full-time in 1969, and took over the Magellan Fund in 1977. At the time, Magellan had $18 million in assets and was closed to new investors.

When Lynch retired at 46 in 1990, it had $14 billion and was the largest actively managed mutual fund in the world. He beat the S&P 500 in 11 of his 13 years managing it.

He's been a vice chairman at Fidelity in an advisory capacity ever since.

Warren Buffett

His main vehicle is Berkshire Hathaway — a company he took over in 1965 when it was a dying textile mill. He basically gutted the textile business and turned the whole thing into a giant money machine that owns other businesses.

Today it's one of the most valuable companies on earth. On the stock side, his biggest bet is Apple — worth over $175 billion at its peak.

He also owns huge chunks of Bank of America, Coca-Cola (since 1988 — he really doesn't sell), American Express, and Chevron. Then there are the companies Berkshire owns outright.

GEICO, one of the biggest car insurers in America. Burlington Northern Santa Fe, a massive railroad.

Dairy Queen, See's Candies, Duracell. Basically a random collection of boring, cash-generating businesses that he loves precisely because they're boring.

His first fund — Buffett Partnership Ltd. — ran from 1956 to 1969.

He returned around 30% per year while the market did 8.6%. Then he shut it down, said he couldn't find enough cheap stocks, and walked away at the top.

Peter Lynch

His entire professional life ran through Fidelity Investments. He managed the Magellan Fund from 1977 to 1990 — 13 years of sustained outperformance that has never been matched at that scale.

His major holdings during that run included Fannie Mae, which he rode from $2 to $40; Chrysler, which he bought near bankruptcy; and various retailers that nobody on Wall Street wanted to touch.

He was famous for finding companies in everyday life before analysts noticed them. He found Dunkin' Donuts because his wife liked the coffee.

He investigated L'eggs pantyhose after his wife bought them at a grocery store. He'd walk through a shopping mall and watch which stores were packed and which were empty — and then go home and read the financials to see if the story held up.

Warren Buffett

University of Nebraska–Lincoln (B.S. in Business Administration, 1950).

Columbia Business School (M.S. in Economics, 1951) — the only school that mattered, where he studied under Benjamin Graham and got his only A+.

He also spent two years at the Wharton School before transferring. Harvard Business School rejected him.

He's described that rejection as one of the luckiest things that ever happened to him.

Peter Lynch

Boston College, class of 1965 — history, psychology, philosophy. Wharton School of Business, MBA.

He's on record saying studying history at Boston College was more useful for investing than anything he learned at Wharton. The historical pattern recognition, the ability to contextualize events — that showed up in how he thought about cycles and companies.
