Nick Sleep

Investor & Co-Founder, Nomad Investment Partnership

Nick Sleep

Nick Sleep is the British investor who, with partner Qais Zakaria, ran the Nomad Investment Partnership from 2001 to 2014 and compiled one of the great long-term records in modern investing: a cumulative return of about 921% (roughly 18.4% annualized after fees) against 117% for the MSCI World Index. Sleep did not beat the market through clever timing or constant trading. He won by thinking in decades, concentrating in a handful of businesses, and refusing to sell.

An Unconventional Path

Sleep studied geology and geography at university and, before finance, worked in a department store, in technology, and even as a sponsored windsurfer—an unconventional route that trained him to think in systems and long time horizons rather than quarterly scorecards. He came to investing through Edinburgh's understated fund-management tradition and an old book on investment trusts, approaching markets as an intellectual investigation rather than a contest.

The Scale-Economy-Shared Thesis

Sleep's central insight was "scale economies shared." He argued that a few rare companies deliberately pass the benefits of scale on to customers—lower prices, better service, wider selection—thereby widening their own economic moat and accelerating growth. Costco was his archetype; he viewed Amazon as an accelerated version of the same idea, and Berkshire Hathaway as a permanent holding alongside them. By holding these compounders through volatility, Nomad let compounding do the work that activity cannot.

Concentration and Patience

Nomad typically held about ten core positions and sometimes let a single winner—Amazon—grow to roughly 40% of the portfolio. This long-term holding discipline, uncomfortable for most institutions, flowed from a clear circle of competence and a willingness to accept short-term underperformance for long-term correctness. Sleep evaluated businesses by their owner earnings and intrinsic value, not by quarterly benchmarks, and he published his partnership letters on a charity website as a statement of values.

A Letter to Buffett

In 2014, having decided to return capital and close the fund, Sleep wrote a thank-you letter to Warren Buffett, noting that Nomad's results were really the achievement of the businesses it owned—and that Berkshire had been an important contributor. He advised his own clients to simply own Berkshire, Costco, and Amazon and "do nothing" for a decade. He then left the industry for philanthropy, establishing a respite-care center, and told Buffett he would not be so easily shaken off.

Lessons for the Serious Investor

His partnership letters carried a refrain—"we don't want to be busy, we want to be right"—and he practiced it by holding through the dot-com collapse and the 2008 crisis without abandoning his thesis. After closing Nomad, Sleep reportedly placed his own capital across Berkshire, Costco, and Amazon and let it compound untouched, a personal echo of the advice he gave his partners.

Sleep is a pure embodiment of patient capital allocation and concentration. His career shows that you do not need to trade often to win—you need to be right, wait, and let compounding run. For value investors, he is proof that the old rules, applied with exceptional temperament, still compound across markets and generations, and that knowing when to stop is itself a form of wisdom.
