Bill Ackman

Ackman is a concentrated, long-hold, activist investor. He typically owns 5–10 positions at a time — sometimes fewer.

Each one involves exhaustive research. If he's buying, he has usually already built a 100-slide deck explaining exactly what's wrong with the company and exactly what needs to change to fix it.

His style is the opposite of index investing. He wants a controlling voice at the table.

He wants to talk to the CEO. He wants the board to change.

That's the "activist" part — he's not just buying a stock and hoping it goes up. He's buying it with a plan to force the thing that will make it go up.

The strategy works until it doesn't. When the thesis is right, he wins massively.

When the thesis is wrong and he's also very public about it, the losses are spectacular.

Davis covers the full crypto market — not just Bitcoin. His content focuses on identifying altcoin opportunities, understanding new blockchain projects, DeFi protocols, and layer-2 ecosystems.

His strategy is higher risk than Bitcoin-only: he looks for early-stage projects with high upside potential and significant downside risk. He has been transparent about both wins and losses in his portfolio.

He advocates dollar-cost averaging into positions and taking profits during bull markets — lessons he admits he learned the hard way during the 2018 bear market.

Ackman's core belief is that markets frequently misprice assets when the story around them is either too negative or too complicated. He looks for businesses he can understand deeply, with a gap between what the market thinks they're worth and what he thinks they're worth.

He's talked extensively about asymmetric bets — situations where you can be wrong and lose a small amount, but right and make a lot. He believes activist investing works because most company boards are too comfortable and most CEOs have too little accountability.

He thinks public pressure, when backed by real analysis, is a legitimate tool for creating value. Whether that makes him a hero or a villain depends on which company you ask.

Lark Davis

His philosophy is that crypto represents the biggest wealth transfer opportunity of his generation. He believes in holding Bitcoin as a base position and using a portion of the portfolio for higher-risk altcoin exposure.

He has said his biggest financial lesson was not taking profits during the 2017-2018 bull run — a mistake he actively advises his audience to avoid repeating.

Bill Ackman

Ackman runs highly concentrated books and uses leverage. That's the opposite of conservative.

He'll put 20–30% of the fund in a single position if he believes in it. He also uses options and credit derivatives — his March 2020 COVID hedge was built using credit default swaps, instruments most retail investors have never heard of.

He famously described his risk approach as: "I only invest when the downside is zero and the upside is unlimited" — which sounds great until you lose $4 billion on one trade. The honest version is: he's a high-conviction investor with a high tolerance for pain on the way to being right.

Davis has been public about holding altcoins that went to zero and investing in projects that turned out to be fraudulent or simply failed. He does not hide the losses.

His risk management has evolved directly from those mistakes: he now advocates taking partial profits at every major price milestone, maintaining Bitcoin as a core position, and treating altcoins as a speculative sleeve rather than a primary strategy. The lesson he repeats most often from 2018: not taking profits during euphoria is itself a high-risk decision — most people just don't recognize it as one until prices have already collapsed.

Ackman has a taste for the finer things and doesn't pretend otherwise. He owns a large Manhattan apartment, he's been photographed at high-end charity events, and his social circle overlaps with New York media, finance, and political elite.

He and his second wife, Neri Oxman, have a high public profile — she's a former MIT professor and design pioneer. He gave $25 million to Harvard (his alma mater), though the relationship became famously strained in 2023 when he led a very public campaign against Harvard's president over campus antisemitism, ultimately contributing to her resignation.

He is not a guy who stays quiet about anything.

He exercises consistently, says a healthy body supports a clear financial mind, and advocates for a simple, mobile lifestyle. Does not flaunt luxury publicly.

The COVID hedge in March 2020 is the one. As markets started selling off in late February, Ackman quietly spent $27 million buying credit default swaps — basically insurance on corporate bonds defaulting if the economy collapsed.

He then went on CNBC on March 18, 2020, visibly emotional, and said "hell is coming." The market kept dropping. Three weeks later, he unwound the trade.

The $27 million had turned into $2.6 billion. That's roughly a 100x return in under a month.

He used the proceeds to buy stocks at the market bottom. He then made another fortune as markets recovered.

The whole sequence — hedge, cry on TV, buy the dip, profit — is one of the more remarkable individual trade sequences in recent hedge fund history.

Building one of the largest crypto education YouTube channels in the world during the 2020-2021 bull run. His coverage of DeFi and altcoin projects during that period — when those sectors exploded in value — brought him the majority of his audience and income.

His Wealth Mastery community grew substantially during that period.

The Valeant Pharmaceuticals disaster is the one. Ackman built a massive position in Valeant starting in 2015, eventually owning about $4 billion worth of shares.

His thesis was that Valeant's model — aggressively raising drug prices and cutting R&D — was brilliant. Congress, journalists, and eventually the SEC had a different view.

The stock collapsed from $260 to under $10. Ackman spent months publicly defending the position, appearing on CNBC repeatedly to explain why it would recover.

It didn't. He finally sold in 2017 at a loss of approximately $4 billion.

It's the most expensive public loss in hedge fund activism history. The lesson he's cited: don't get emotionally attached to a position, and be faster to recognize when the fundamental thesis has broken.

In 2021, Davis faced significant controversy when it emerged he had been paid to promote certain crypto projects to his audience without clearly disclosing the payments. He issued an apology and said he had followed what he believed were disclosure norms at the time, but the episode damaged his reputation and became one of the most-cited examples of undisclosed crypto influencer promotions.

He also, like most altcoin-focused analysts, saw his portfolio take brutal losses in the 2022 bear market.

Bill Ackman

Bill Ackman grew up in Chappaqua, New York, the son of a real estate finance chairman. He was a history major at Harvard — class of 1988 — then went straight to Harvard Business School.

His first venture was Gotham Partners, a real estate and value investing fund he started in 1992 with a Harvard classmate. It was a disaster.

The fund made concentrated bets on illiquid real estate and had to be wound down by 2003 under serious investor pressure and SEC scrutiny.

He didn't quit. In 2004 he launched Pershing Square Capital Management, this time with a clearer focus: take large stakes in companies, go public with his thesis, and use activist pressure to force management changes.

The approach worked. His reputation was built on detailed, public investment presentations — sometimes running 100+ slides — that became must-reads on Wall Street.

He turned activist investing into something that felt more like journalism than finance: research a company, find what's broken, publish everything, and bet heavily on being right.

Lark Davis is a New Zealand-born crypto educator who built his brand primarily on YouTube, starting around 2018. He focuses on cryptocurrency analysis with an emphasis on altcoins, DeFi, and emerging blockchain projects — not just Bitcoin.

His channel "Crypto Lark" grew to over a million subscribers, making him one of the most followed retail crypto educators in the world. He also built a paid subscription community, Wealth Mastery, where he publishes deeper research.

He has lived in Thailand for years, part of a wave of digital nomad crypto educators who operate internationally.

Pershing Square Capital Management is his flagship hedge fund, managing around $16 billion. His most famous public positions have included Canadian Pacific Railway, where he pushed successfully for a new CEO and a turnaround that made Pershing Square hundreds of millions.

He held a massive position in Valeant Pharmaceuticals from 2015 to 2017 — which will come up again. He took a huge bet on General Growth Properties during the 2008 financial crisis when no one else would touch it.

That one returned over $1 billion.

He has also done business on the other side: Pershing Square Holdings is his publicly listed vehicle on Euronext Amsterdam, which lets retail investors access his fund — unusual for a hedge fund of this size. He's been a major Burger King and Restaurant Brands International investor, and he backed Fannie Mae and Freddie Mac preferred shares in a long-running legal battle with the government.
