Super Investor #29 in our series is Nick Sleep – The Master of Scale Economies Shared. Nick Sleep is one of the most intriguing yet lesser-known super investors in modern finance. As the former manager of the Nomad Investment Partnership, Sleep built a reputation for his deep, long-term conviction in a few high-quality businesses. His investment philosophy revolves around a powerful concept he coined: “scale economies shared”, which led him to make early, highly successful bets on companies like Amazon (AMZN) and Costco (COST).
Though he retired from professional investing in 2014, his influence remains strong among buy-and-hold investors who seek to build wealth through patience, concentration, and business quality. In this article, we’ll explore Sleep’s background, investment strategy, key stock picks, and the valuable lessons individual investors can learn from him.
1. The Early Life and Background of Nick Sleep
From Academia to Investing
Unlike many famous investors, Sleep’s rise to prominence was relatively quiet. He studied geography at the University of Oxford, a subject that, while not directly related to finance, helped him develop a macro perspective on how businesses and economies evolve over time.
His career began at Marathon Asset Management, where he learned the principles of long-term investing and thinking differently from the market. These early experiences shaped his approach when he later co-founded the Nomad Investment Partnership with his colleague, Qais Zakaria.
The Birth of Nomad Investment Partnership
In 2001, Sleep and Zakaria launched Nomad Investment Partnership, a fund that would eventually deliver market-beating returns over 13 years. While the exact figures are private, estimates suggest a 20%+ annualized return, significantly outpacing the S&P 500.
Despite their success, Sleep and Zakaria made an unusual decision: in 2014, they returned all investor capital and retired. Sleep has largely stepped away from the investing world since then, but his ideas continue to inspire those who seek to compound wealth through high-quality businesses.
2. Nick Sleep’s Investment Philosophy & Strategy
Core Investment Principles
Sleep’s investment philosophy can be broken down into four key principles:
- Scale Economies Shared – His most famous concept, which we’ll explore in detail below.
- Long-Term Thinking – Sleep often held stocks for decades, believing that short-term market movements were irrelevant.
- Concentrated Investing – Rather than diversifying widely, Sleep focused on a few high-quality businesses with strong compounding potential.
- Minimal Trading – His portfolio had very low turnover, as he preferred to let winners run.
What Is Nick Sleep’s “Scale Economies Shared”?
At the heart of Sleep’s strategy is scale economies shared—the idea that as companies grow, they should pass their cost savings to customers rather than maximizing short-term profits. This builds long-term customer loyalty, leading to stronger competitive advantages and sustained growth.
Amazon (AMZN) – The Perfect Scale Economies Shared Example
Sleep identified Amazon early on, recognizing that Jeff Bezos was constantly reinvesting profits to lower prices, improve delivery, and enhance customer experience.
Most analysts at the time were skeptical because Amazon didn’t focus on maximizing profits. But Sleep understood that this strategy would eventually create an unstoppable flywheel, attracting more customers and increasing scale advantages. Today, Amazon is one of the world’s largest companies, and its stock has delivered massive returns.
Costco (COST) – Another Textbook Example
Costco operates on a similar principle—it reinvests its profits to lower prices for customers. While competitors focus on maximizing margins, Costco sacrifices short-term profits to maintain a loyal customer base that spends more over time.
Sleep recognized this model’s power and made Costco a core holding. Over time, the company’s ability to compound value through reinvestment proved him right.
Why Nick Sleep’s Approach Works
Businesses that prioritize scale economies shared tend to develop:
- Higher customer loyalty
- Stronger competitive moats
- Better reinvestment opportunities
- Long-term, compounding returns for investors
This is why Sleep believed that buying and holding these companies for decades was the best way to generate wealth.
3. Notable Investments & Track Record of Nick Sleep
Biggest Wins
- Amazon (AMZN) – A massive multi-bagger investment based on the scale economies shared concept.

- Berkshire Hathaway (BRK.B) – Warren Buffett’s conglomerate, known for its long-term compounding approach.
While the full details of his portfolio remain private, these holdings demonstrate his preference for dominant businesses with sustainable competitive advantages.
Any Big Losses?
Unlike many investors, Sleep rarely made high-risk bets or invested in speculative stocks. His approach focused on minimizing losses by investing only in predictable, high-quality businesses.
However, he did exit some investments too early. For instance, he sold Amazon too soon, missing out on some of its later gains. But even then, his disciplined approach ensured that his winners far outweighed any mistakes.
4. Nick Sleep’s Lessons for Individual Investors
Key Takeaways from Nick Sleep

How to Apply These Lessons

- Hold for the long run: Aim for at least 10-20 years rather than jumping in and out of stocks.
