Carl Icahn

Icahn buys undervalued companies with bad management. His thesis is consistently the same: there is enormous value being destroyed by entrenched executives who are more interested in keeping their jobs than returning value to shareholders.

He buys enough stock to force a confrontation. Sometimes management cleans itself up just from the threat of his involvement.

Sometimes he installs new people. Sometimes he forces a full sale of the company.

His version of value investing is more aggressive than Graham''s or Buffett''s. He doesn''t wait for the market to recognise value.

He forces the recognition. He is comfortable with conflict in a way most investors are not.

He sees confrontation with management as part of the job — not an unfortunate side effect of it.

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.

Carl Icahn

He genuinely believes management teams destroy shareholder value through complacency, self-dealing, and entrenchment. He sees himself as a corrective force — not a vulture, but a mechanism by which markets hold management accountable.

Whether that''s how it looks from inside the companies he targets is a different question. His rules: buy when nobody else wants it, apply pressure to unlock the value, sell when the value is recognised.

Don''t get sentimental about positions. Don''t let management tell you the company is more complex than it looks.

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: loving a company's product is not enough on its own — you still have 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.

Carl Icahn

He concentrates. He uses leverage.

He''s comfortable with positions that make other investors deeply uncomfortable. He''s also comfortable being wrong in public — he''s had positions go spectacularly badly and he doesn''t hide from them.

His Hertz position went bankrupt during COVID. His Herbalife long was a very public, very watched position on the opposite side of Bill Ackman''s short.

He doesn''t bluff. When he says he''s going to fight, he fights.

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.

His rule was that you should never own more companies than you can actually keep track of. He could track hundreds because researching them was his full-time job.

For everyone else the honest number is far smaller, and he said so.

Carl Icahn

He lives in Sunny Isles Beach, Florida. He works ferociously hard and has done so into his 90s.

He''s a hands-on manager — not someone who delegates. He famously said: "If you want a friend on Wall Street, get a dog." He has a Maltese named Tiger.

He''s been a prolific poker player and was once considered one of the best amateur players in New York. He remarried in 1999.

His current wife is Gail Golden. He''s given some money to charity but not at the scale of Buffett or Gates — he''s made no secret of prioritising returns over philanthropy.

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.

Carl Icahn

Apple. In 2013 he disclosed a $1.5 billion stake in Apple and published an open letter to Tim Cook urging a larger share buyback.

Apple eventually announced a significantly expanded buyback program. The stock rose.

Icahn made approximately $2 billion on the position. He didn''t have to engineer a hostile takeover — just making his involvement public was enough to move one of the largest companies in the world.

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.

Carl Icahn

TWA. He took over Trans World Airlines in 1985 using a leveraged buyout, extracted cash from the company to pay back the acquisition debt, and sold the valuable London routes to American Airlines for $445 million.

By the time he was done, TWA was a financially gutted airline. It went bankrupt in 1992, again in 1995, and was absorbed by American Airlines in 2001.

Icahn personally made hundreds of millions. The airline''s employees and creditors did not.

He''s defended his actions as legal. Legal and good for everyone are not always the same thing.

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.

Carl Icahn

Carl Icahn grew up in Far Rockaway, Queens. His father was a failed opera singer who became a synagogue cantor.

Icahn studied philosophy at Princeton — graduated 1957 — then enrolled in NYU School of Medicine before dropping out after two years to join the army. He became a stockbroker at Dreyfus & Co.

in 1961, saved $400,000, and bought a seat on the New York Stock Exchange in 1968.

He spent the early years running option arbitrage — finding and exploiting small mispricings. He was very good at it.

In the late 1970s he pivoted to a bigger game: buying large stakes in undervalued companies and forcing management changes. His first major target was Tappan Company in 1979.

By the mid-1980s he was feared by corporate boards across America. Oliver Stone''s Gordon Gekko in Wall Street is directly based on the era Icahn created.

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.

Carl Icahn

Icahn Enterprises is his publicly traded holding company. He''s been chairman since 1987.

Some of his most famous investments: TWA, which he took over in 1985, stripped its most valuable routes to pay back the debt used to acquire it, and left financially hollowed out — it went bankrupt twice after his tenure. Texaco, where he forced a settlement that paid shareholders.

Apple, where he took a $1.5 billion position in 2013 and published an open letter to Tim Cook demanding a larger share buyback. Apple eventually expanded the buyback.

The stock rose. Icahn made roughly $2 billion on the position without engineering a hostile takeover — the threat of his involvement was enough to move a $500 billion company.

He''s also had notable losses. Hertz went bankrupt during COVID while he held a large position.

He lost hundreds of millions.

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.

Carl Icahn

Princeton University, BA in Philosophy, 1957. NYU School of Medicine, dropped out after two years.

He''s credited Princeton''s philosophy training with teaching him to question conventional wisdom — which shows up directly in how he argues with corporate boards.

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.
