Ruane Cunniff (Sequoia Fund)
The firm behind the legendary Sequoia Fund — founded by Bill Ruane, recommended by Warren Buffett himself, and built on concentrated investment in a handful of wonderful businesses held for the long run.
Who they are
When Warren Buffett wound down his investment partnership in 1969, he pointed his partners toward his friend Bill Ruane, who had just launched the Sequoia Fund through Ruane, Cunniff & Goldfarb.
Sequoia went on to become one of the most studied mutual funds in history, compounding for decades with a tightly concentrated portfolio of high-quality businesses.
Core philosophy
The firm looks for a small number of durable, well-managed businesses bought at sensible prices, then holds them for years, letting compounding do the heavy lifting.
Deep, original research and a willingness to concentrate in their best ideas define the approach — quality first, with valuation discipline, rather than chasing broad diversification.
Key lessons for individual investors
- A handful of wonderful businesses can outperform a sprawling portfolio.
- Concentration works when paired with deep, original research.
- Quality and durability matter as much as a cheap price.
- Long holding periods let compounding compound.
- Independence of thought beats following the crowd.

The $25 million lesson that changed Buffett
In 1972 the sellers of See's Candies asked $30 million; Buffett, trained on Graham's cigar butts, refused to go above $25 million — roughly three times book value, a price the old Buffett would never pay. The deal nearly died over $5 million. Charlie Munger pushed back: a beloved brand with loyal customers and genuine pricing power deserved a premium.
They paid the $25 million. See's went on to ship more than $1.65 billion of cumulative pre-tax earnings back to Omaha while needing almost no additional capital — raising prices every year without losing a single loyal customer. Buffett later called it 'the prototype of a dream business' and credits this one purchase with rewiring how he invests.
Quality compounds quietly for decades. Temperament and a clear circle of competence beat chasing the cheapest price.
A fair price for a wonderful business
In 1988, just months after the Black Monday crash, Warren Buffett quietly began buying Coca-Cola shares. By 1989 Berkshire had spent roughly $1 billion — at about 15 times earnings, hardly a statistical bargain. Wall Street was puzzled: the "cigar-butt" student of Graham was paying up for a household brand.
Buffett was not valuing the next quarter. He was estimating decades of predictable owner earnings from a product sold in nearly every country on earth, protected by the strongest brand moat in consumer goods. Ten years later the stake was worth more than $13 billion, and Berkshire still holds it today — the annual dividends alone now return a large share of the original cost every single year.
A valuation model exists to estimate long-term cash generation — not to find the statistically cheapest ticker on the screen.
A quality compounder hiding in plain sight
In 2016, with Apple trading near 10–12 times earnings amid fears the iPhone cycle had peaked, Berkshire began buying — eventually about $36 billion of stock. Buffett's thesis required no technology forecast: a product customers would not abandon, extraordinary returns on invested capital, and a buyback machine that increased Berkshire's ownership share every year without another dollar spent.
The stake grew to be worth more than $150 billion at its peak — the most profitable single investment in Berkshire's history, earned not by predicting gadgets but by recognizing a high-ROIC franchise priced like a metal-bender.
High returns on capital plus a shrinking share count quietly multiply your slice of the profits.
