Introduction
Medieval castles had Moats against enemies.Businesses have Economic Moats — advantages competitors can't easily copy.Buffett: "Wide and deep moat around the business."
Core Concepts
Financial Terms
| Term | Meaning |
|---|---|
| Economic Moat | Durable competitive advantage |
| Pricing Power | Raise prices without losing demand — moat test |
| Wide vs Narrow Moat | Decades vs limited advantage |
| Moat Erosion | Technology, regulation, preference shift weaken moat |
| Network Effects | More users → more value → flywheel |
| Switching Costs | Cost/risk of changing product |
| ROCE | Proxy for moat quality over time |
Investment Decision
10 Moat Questions: Can raise price? Customers sticky? Easy to copy? Market share stable? ROCE high? Margins stable? Brand strong? Distribution strong? Network effects? Advantage lasts 10 years?
| Moat Score | Action |
|---|---|
| Wide (24+) | Premium valuation may be justified |
| Moderate | Need margin of safety |
| Weak | Avoid or deep value only |
"Growth can make you rich. A moat keeps you rich for decades." — Warren Buffett
- Brand Moat — Apple; India: Titan, Asian Paints, HUL
- Cost Advantage — Bulk buying, scale, efficient supply chain
- Network Effects — Social, payments, marketplaces
- Switching Costs — Enterprise software, banking relationships
- Distribution Network — FMCG across millions of outlets (India strength)
- Regulatory Moat — Banking, exchanges — not permanent
- Intangible Assets — Patents (Pharma — expire over time)
Pricing Power Test: Can company raise price without demand drop? Yes → likely moat.
Formula & Explanation
Moat Purpose
No moat: High profit → competition → profit falls.
Long-Term ROCE Link
Great companies: ROCE > 20% sustained — competitors can't steal profits easily.
Network Effect Flywheel
Growth + Moat
Growth attracts competition — without moat, growth doesn't stick.
Moat Scorecard (30 points)
Brand, Cost Advantage, Network Effects, Switching Cost, Distribution, Regulation — each 0–5.
| Score | Meaning |
|---|---|
| 24+ | Wide Moat |
| 18–23 | Moderate Moat |
| <18 | Weak Moat |
Visual Guide
Worked Example — Indian Market
Example 1 - Scalability
Revenue doubles in 3 years with stable gross margin -> operating leverage at work.
Example 2 - Moat
Brand + distribution = pricing power through inflation cycles.
Real World Example
Tea Shop A: Good tea — anyone can open opposite.Tea Shop B: Famous brand — customers pay premium, won't switch easily.Shop B = Moat — brand trust creates pricing power.
Case Study
| Type | India/Global Example | Moat Source |
|---|---|---|
| Consumer | Asian Paints, ITC | Brand + Distribution |
| Software | TCS, Infosys | Switching cost + relationships |
| Banking | HDFC Bank, ICICI Bank | Trust + Distribution + Regulation |
| Commodity | Steel, Coal | Moat hard — valuation discipline critical |
CFA Exam Tip
Buffett: "Determine the competitive advantage — above all, the durability of that advantage."
Professional asks: "How much damage can competitors inflict?" — not just "Is company good?"
Moat erodes via: Technology disruption, Regulation, Poor management, New competition, Consumer shift — regular review required.
Common Mistakes
- Technology Disruption threat
- Regulation change
- Declining ROCE over 5+ years
- Market share loss to new entrants
- Temporary advantage mistaken for moat
Common Mistakes
- Brand alone without economics
- Temporary advantage = moat
- ROCE ignore
- Technology risk ignore
- Valuation ignore (even wide moat can be bad buy)
Key Takeaways
- Moat = sustainable competitive advantage; pricing power = key test.
- 7 types: Brand, Cost, Network, Switching, Distribution, Regulatory, Intangible.
- ROCE > 20% long-term signals strong moat.
- Moats erode — durability matters most.
- Growth + Moat = compounding wealth machine.
