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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
