The method begins with a structural change such as machine learning, autonomous driving, or a new healthcare market. Analysts then search for businesses that both drive the shift and possess superior products, secular demand, and barriers to entry. Deep company-level research tests whether these advantages can produce sustained growth. Only the strongest conclusions earn meaningful portfolio weights, creating a concentrated collection of companies rather than a benchmark-like basket. Because market leadership can take time to emerge, positions are judged over several years and temporary volatility is tolerated unless it undermines the company’s fundamentals. The intended output is stock-selection alpha from a small number of durable winners.

Core principles
- 01Research depth must justify portfolio concentration
- 02Seek structural growth rather than temporary momentum
- 03Favor businesses with defensible barriers to entry
- 04Judge companies independently of benchmark weights
- 05Allow long holding periods for a thesis to mature
How to run it
- 1
Locate a structural shift
Identify an enduring change in technology, consumer behavior, healthcare, or another industry that can create years of demand.
Pro tip Distinguish a secular shift from a short-lived cyclical surge.
Watch out A popular theme is not automatically a durable structural change.
- 2
Find the potential leaders
List the companies delivering the strongest products or business models within the shift.
Pro tip Look beyond the largest incumbent when a smaller company is redefining the market.
Watch out Do not confuse rapid industry growth with company-specific advantage.
- 3
Test the moat
Examine barriers to entry, product superiority, pricing power, customer loyalty, and control of the value chain.
Pro tip Ask what would prevent a well-funded competitor from copying the business.
Watch out A growth rate without a defensible moat may attract competition and collapse.
- 4
Research independently
Build the thesis from company fundamentals rather than benchmark composition or a centralized house view.
Pro tip Use experienced sector analysts who can challenge management assumptions.
Watch out Benchmark awareness can silently turn independent research into index imitation.
- 5
Concentrate by conviction
Give meaningful weights only to the companies supported by the strongest research conclusions.
Pro tip Let position size reflect evidence and conviction, not excitement.
Watch out Concentration magnifies the cost of weak analysis.
- 6
Hold through the thesis
Use a three-to-five-year horizon and filter out volatility that does not change the company’s underlying prospects.
Pro tip Write down the fundamental conditions that would invalidate the position.
Watch out Long-term investing must not become an excuse to ignore a broken thesis.
In the wild
An analyst identifies machine learning as a structural shift, compares infrastructure providers, and finds one with superior technology, high switching costs, and expanding secular demand. After testing valuation and competitive threats, the company receives a meaningful portfolio weight and is held while adoption develops.
→ The portfolio gains focused exposure to a potential structural winner backed by a documented thesis.
Common mistakes
Buying the theme instead of the company
A powerful trend cannot compensate for weak economics, poor execution, or an undefended business model.
Concentrating before researching
Large positions should be the consequence of deep evidence, not a substitute for it.
Reacting to every price move
Short-term volatility should trigger a fundamental review, not automatic trading.
Is it for you?
Best for
It is best for experienced fundamental investors with long horizons and tolerance for benchmark-relative volatility.
Not ideal for
It is unsuitable for investors who require broad diversification, low tracking error, or dependable short-term performance.
From the transcript
“what we're looking for is innovative and disruptive businesses driving structural shifts and industries.”
“You know, business models with with significant barriers to entry, secular demand trends driven by superior product offerings”
“history has shown that market returns over time have been driven by a narrow set of disruptors and consistent winners.”
