Between 2001 and 2014, Nick Sleep's Nomad Investment Partnership returned roughly 921% — almost eight times the MSCI World Index — by holding just three stocks: Amazon (AMZN), Costco (COST), and Berkshire Hathaway (BRK.B). The simplest framework in modern investing also turned out to be one of the most powerful.
How Did Nick Sleep Get Started?
Sleep began his investment career as an analyst at Marathon Asset Management in London, where he developed a fascination with companies whose business models created compounding advantage rather than merely milking existing assets. In 2001, he and his partner Qais Zakaria launched Nomad Investment Partnership with about $20-30M of seed capital from family offices and a few institutions.
The fund was structured as a partnership rather than a public mutual fund. That gave Sleep two things: very long-duration capital from limited partners willing to lock up money for years, and protection from the marketing treadmill that forces most public funds to chase returns quarter-to-quarter.
Nomad started life as a global value fund. Its early letters discussed Zimbabwean cement makers, Norwegian shipping families, and Indian motorcycle manufacturers — the kind of obscure micro-caps that traditional value investors loved. By 2005, Sleep had quietly begun shifting toward something different: large, scale-driven businesses where the moat got wider as the company grew.
That shift became the entire story.
What is Scale Economies Shared?
Scale economies shared is the framework Sleep developed to describe businesses that deliberately pass scale advantages back to customers as lower prices, rather than capturing the full benefit as margin. The result is a self-reinforcing loop: lower prices drive more customers, which drives more scale, which drives lower prices.
COST is the cleanest example. The membership warehouse marks up products only about 11-15% over cost — far below the typical retail markup of around 25-30%. Lower prices attract more members. More members buy more units. Suppliers offer better pricing because of the volume. Costco then passes the savings back, which attracts more members. The loop tightens with every revolution.
Sleep saw the same pattern in AMZN when most investors saw a money-losing online bookstore. Amazon was deliberately keeping prices below what the market would bear, sacrificing near-term profit for share gain. The 2006 Nomad letter laid out why this was a feature, not a bug. He bought aggressively when Wall Street was still skeptical.

What Are the Five Principles Behind Nomad's Success?
Five principles, distilled from the partnership letters and Sleep's later interviews:
First, prefer durable business models over cheap multiples. Sleep was not chasing low-P/E stocks. He was chasing businesses whose competitive position would be stronger in 10 years than today. He paid up for AMZN when traditional value screens flagged it as overpriced.
Second, concentrate when conviction is high. By the late 2000s, Nomad held roughly 60-70% of capital in three positions. Most fund managers cannot do this for career-risk reasons. Sleep could because his LPs had agreed to long lockups and because he was honest about the implications.
Third, keep turnover near zero. Nomad's portfolio turnover was famously low — single-digit percentage per year. Sleep argued that taxes and trading costs are the silent compounding killers, and that the right businesses do not need to be sold.
Fourth, ignore the consensus. Sleep wrote glowingly about AMZN and COST at moments when sell-side ratings were lukewarm. He treated downgrades as a signal that the market was misjudging the business's long-term trajectory.
Fifth, build the right investor base. Nomad's LPs were screened for patience, not just capital. Sleep argued that the wrong shareholders force the wrong decisions.
Famous Quotes from the Nomad Letters
The letters themselves are some of the most lucid investor writing of the past two decades. A few representative passages:
"In the case of Costco scale efficiency gains are passed back to the consumer in order to drive further revenue growth."
"The deep reality is that one of the most important inputs is patience. The market does not reward patience evenly. The market rewards patience when it is paired with the right kind of conviction in the right kind of business."
"We have come to understand the world more in terms of motion. Some companies are moving forward, others are moving backward. The cheap multiple often signals motion in the wrong direction."
These quotes, paraphrased from the partnership letters, capture why his framework resonated with peers including Bill Miller, Mohnish Pabrai, and Guy Spier.
What Stocks Made Nomad's ~921% Return?
The famous three holdings carried most of the load. By the end of the partnership in 2014, Nomad held a heavy weighting in AMZN, COST, and BRK.B, with smaller positions in companies that fit the scale-economies-shared template.

Notice the pattern. Most of these names look ordinary on a 12-month chart but compound at high rates over 10-20 year windows. The selection criterion was not "what will go up next quarter" but "what business will look qualitatively bigger in a decade."
Why Did Nomad Beat the MSCI by ~8x?
Three reasons, in order of importance.
First, the businesses themselves. AMZN compounded gross profit at roughly 25-30% for over a decade. COST doubled operating income about every six years. BRK.B compounded book value in the high single digits. The portfolio's underlying earnings power simply grew faster than the index.
Second, the concentration. The math of running a 50-name fund means winners are diluted by the average. Nomad's top three names allowed full exposure to the underlying compounding without the diversification drag.
Third, the holding period. Sleep let positions run for a decade or more. The compounding inside AMZN and COST only became visible after several years of patient holding. Most fund managers would have trimmed both names well before the bulk of the returns showed up.
That last point matters. The 921% number is not just stock selection — it is selection plus discipline plus structure. Remove any one of the three and the result collapses.
What Can Today's Investors Learn From Nick Sleep?
Several things, but be careful about what you copy.
The most copyable lesson is the framework: look for businesses that pass scale benefits back to customers, because the loop strengthens over time. The current candidates that look most like this template include AMZN (still), COST (still), and arguably Netflix (NFLX) when content investments amortize. Whether AAPL qualifies is a more interesting debate — it tends to capture rather than share its scale benefits.
Less copyable is the concentration. Sleep was working with capital from sophisticated LPs with multi-year lockups. A retail investor copying his exact 60-70% concentration in three names is taking on volatility that most household balance sheets cannot absorb. The principle generalizes; the position sizing does not.
Even less copyable is the discipline to do nothing. Sleep wrote in one letter that "the central rule of investing is do not interrupt compounding unnecessarily." That is easier to write than to live with. Holding AMZN through the roughly 50% drawdown in 2008 required ignoring almost every external signal — and most investors will not.

What Could Go Wrong With This Framework?
Three things. First, "scale economies shared" can degrade. Companies that pass benefits back when small can shift toward capturing margin once dominant — the discipline often weakens with size. WMT is sometimes cited as an example of this drift.
Second, concentration is binary. If one of the three holdings turns out to be wrong, the portfolio damage is severe. Sleep got lucky in the sense that none of his three central names blew up. The next investor running the same playbook may not.
Third, regulators have started scrutinizing companies that build their position by passing efficiency back to customers. The same flywheel that built AMZN is now the basis of antitrust action in multiple jurisdictions. The framework that worked from 2001-2014 may face headwinds it did not face then.
Critics argue Sleep's results were partly a function of being early to a megacycle in technology platforms — and that anyone who held the same three stocks would have done well, regardless of process. Defenders point out that almost no one did hold those three stocks at that concentration for that long. Both arguments have force, which is why the case is still debated.
