Date: March 31, 2026
Hosts: Ben Johnson, Amy C. Arnott
Guest: Pat Dorsey (Founder, Dorsey Asset Management)

Overview

This episode of The Long View features a deep dive into the concept of economic moats with Pat Dorsey—renowned investor, former Morningstar Equity Research Director, and the so-called “moat guy.” The discussion explores the origins and evolution of moat analysis, key pitfalls in evaluating competitive advantage, management quality, founder-led businesses, and practical investing processes for identifying advantaged firms. Throughout, Dorsey shares candid insights, examples from his experience, and frameworks for both professional and individual investors.

Main Themes & Key Discussion Points

1. Defining and Origin of Economic Moats

• Definition: "A moat is just a structural competitive advantage, something that's an attribute of a business that makes it difficult to compete with them and generally lends them some pricing power." – Pat Dorsey [02:05]
• Development: The concept grew out of Dorsey’s time at Morningstar, aiming to differentiate equity research and codify Warren Buffett’s “economic moat” idea.

2. Sources and Types of Moats

• Types by Industry:
  • Consumer products: Brands and scale are most common.
  • B2B software: Switching costs dominate (e.g., SAP).
  • Luxury goods: Primarily based on brand value.
• Key Quote: "It's really just a matter of the type of business, the industry that you're analyzing." – Pat Dorsey [03:41]

3. Common Mistakes in Moat Identification

• Accounting Limitations: Traditional metrics like return on capital often miss moats in capital-light or software businesses.
• Misconflation: Investors often mistake a great product/service for a sustainable moat.
• Key Quote: "You have to think through, how sustainable is that demand, how much pricing power is it going to have over time, how easy would it be to replicate it?" – Pat Dorsey [05:24]

4. Qualitative vs. Quantitative Moat Analysis

• Evolving Metrics: Changes in accounting make some figures (ROIC) less meaningful—especially for tech and software.
• Qualitative Focus: For capital-light businesses, qualitative factors like user captivity, network effects, and habit formation are more informative.

5. "Inevitable" vs. "Non-Inevitable" Moats [08:23]

• Inevitable Moats: Stable, slowly changing businesses (e.g., Coca Cola).
• Non-Inevitable Moats: Dynamic, high-growth industries (e.g., software, semiconductors).
• Implication: Not all moats can be “bought and held” for decades. Some require active monitoring and flexible thinking.

6. Surprises in Moat Durability [10:07]

• Negative Surprise: PayPal's moat faded due to inability to adapt to mobile payments (NFC access) despite large network.
• Positive Surprise: Visa and MasterCard proved more resistant to regulatory changes than expected.
• Key Quote: "PayPal is cut out... and it really lost share because of that." – Pat Dorsey [11:02]

7. Limits of Network Effects [12:34]

• Overestimating the durability and value of network effects is common; actual value and quality of the network for users is essential.
• Analytics Manipulation: PayPal highlighted network stats that did not accurately reflect competitive strength.
• Key Quote: "The value it is delivering to each member of that network is lower today than it was 10 years ago." – Pat Dorsey [13:15]

8. Evaluating Management Quality [14:17]

• Desirable Traits: Humility, willingness to admit mistakes, sharing credit, openness to alternative viewpoints.
• Danger Signs: Overconfidence, refusal to listen, attributing all success to themselves.
• External Signals: Language in earnings calls, conference interviews, and openness in diverse public forums.
• Key Quote: "The dangerous ones, frankly, are the ones who think they're always right and are unwilling to listen to alternative viewpoints..." – Pat Dorsey [15:22]

9. Founder-Led Businesses: Mindset and Pitfalls [17:49]

• Builder vs. Seller: Distinguishes between founders who aim to build long-term value and those who seek a quick exit.
• Scalability Challenge: Skills required for startup success differ from those needed to manage and grow mature, scaled organizations.
• Micromanagement: Becomes a liability as companies grow.
• Example: Airbnb’s challenge with capital allocation as growth slows.
• Key Quote: "...the key thing is simply to evaluate founders of large organizations the exact same way you would non founders and don't give them the benefit of the doubt." – Pat Dorsey [19:40]

10. Management and Pricing Power [22:41]

• Sensible Pricing: Sustainable price increases must reflect added value, not just exploit captive customers.
• Danger: Excessive short-term rent extraction risks turning “moats” into “melting ice cubes.”
• Key Quote: "It's when companies don't reinvest back in the product and... just kind of milk it and raise price because the consumer or user has little other choice. That's a business that is often less sustainable." – Pat Dorsey [24:10]

11. Investment Process and “Too Hard” Pile [25:03]

• Process:
  • Limited use for quantitative screens due to capital-light nature of modern moats.
  • Focus on areas/industries with a higher likelihood of sustainable moats (e.g., aerospace, semiconductors, software).
  • Ignore sectors where moats are rare or fleeting (auto, insurance, banking, energy, commodities).
• “Too Hard” Bucket:
  • Acknowledges when the range of likely outcomes is too wide, or others possess a clear analytical edge.
  • Especially relevant in areas of rapid change like AI/software.
• Key Quote: "When the cone of uncertainty widens a ton... it's probably better to realize that there are lots of potential opportunities out there and you're better off moving on to another." – Pat Dorsey [29:29]

12. “Pre-Mortem” Investment Discipline [30:29]

• Approach: Imagine the investment has failed in five years, then hypothesize causes. Identifies critical thesis risks to monitor closely.
• Purpose: Helps separate meaningful negative data from mere noise and to codify risk factors explicitly.

13. Market Efficiency, Edge, and Behavioral Advantage [32:39]

• Types of Edge:
  • Informational: Rare today, especially for large, covered companies.
  • Analytical: Analyzing better than others.
  • Behavioral: Willingness to think and act long term, while others are captured by short-term noise.
• Key Quote: "It's much easier to have a behavioral advantage... it's actually become easier, I would argue, over the past 10, 20 years..." – Pat Dorsey [34:28]

14. Private Fund vs. Public Fund Structure [36:41]

• Pat prefers private fund model for closer relationships, better communication, and insulating from short-term flow pressures that affect daily-liquid funds.

15. Opportunity Cost Mindset [37:56]

• Emphasizes evaluating all holdings versus alternatives daily, always reconsidering allocations if higher-return opportunities arise (while acknowledging tax friction in some contexts).
• Key Quote: "...when you walk in, you rebuy your portfolio every morning like you're making an active decision..." – Pat Dorsey [39:51]

Dorsey's insights offer a pragmatic guide for investors looking to blend deep analysis with intellectual humility in the pursuit of long-term outperformance.
