Founder of Third Point — an activist investor famous for his sharp "poison-pen letters" to corporate executives.
Life story
Daniel Loeb was born in 1961 in Santa Monica, California. His father, Ronald Loeb, was a partner at the law firm Irell & Manella and general counsel of Williams-Sonoma; his mother, Clare Spark, is a historian. His great-aunt Ruth Handler created the Barbie doll.
Loeb spent two years at UC Berkeley before transferring to Columbia University, where he earned a B.A. in economics in 1983. He was already trading stocks as a student: in his senior year he lost $120,000 on an investment in Puritan-Bennett.
How they got started
Loeb began at private equity firm Warburg Pincus (1984–1987), then worked in corporate development at Island Records and as a risk-arbitrage analyst at Lafer Equity Investors. From 1991 to 1994 he was a senior vice president in distressed debt at Jefferies, and from 1994 to 1995 a vice president in high-yield bonds at Citigroup.
In 1995 he launched Third Point with $3.3 million raised from family and friends. The firm grew into a multi-strategy manager spanning equities (long and short), corporate and structured credit, private credit and venture investing (Third Point Ventures). Today Third Point is based at Hudson Yards in New York, with Loeb as CEO and chief investment officer.
Investment style
Loeb is an event-driven investor: he looks for companies where restructurings, spin-offs or management changes can unlock value. He often buys into troubled or poorly run companies and pushes for new leadership and strategy.
His signature weapon is the sharp, sometimes mocking open letter to CEOs — the "poison-pen letter." Third Point holds stocks over both short and long horizons and turns over its portfolio frequently.
Best decisions
Yahoo (2011–2012)
Loeb exposed that Yahoo CEO Scott Thompson's résumé listed a computer science degree he did not have. Thompson resigned and Loeb won board seats — one of his most famous activist victories.
Sotheby's (2013–2014)
He sharply criticized the auction house's governance and won a seat on its board.
International activism
Third Point also ran campaigns at Sony (2013, proposing to separate entertainment from electronics), Nestlé (2017) and Japan's Fanuc and Seven & i Holdings.
Biggest mistakes
A student-era loss
While at Columbia, his bet on Puritan-Bennett stock ended in a $120,000 loss — an early lesson Loeb has spoken about.
2015
Third Point returned −1.4% in 2015 while the S&P 500 gained 1.4% — a reminder that activism does not always beat the market.
Today
As of 2026 Loeb, 64, remains CEO and CIO of Third Point. The firm has expanded in credit, acquiring the credit manager Birch Grove (now TP Birch Grove). Loeb is also known as chairman of the Success Academy charter school network and as a major art collector.
What to learn from following the portfolio
- A large new Third Point position often signals an activist campaign or an expected corporate event (spin-off, sale) — following the news matters.
- The fund turns over its portfolio quickly, while 13F lags by 45 days: a position you see may already be sold. Shorts and credit positions do not appear in 13F.
- Loeb's public letters and investor letters explain his thesis better than the 13F numbers.
- Halal lens: alongside technology, industrial and consumer companies, Third Point's portfolio also includes banks, insurers and other financials — the latter are typically not halal. Check each position's halal status on the Portfolio tab.
