Here’s a weird truth about the stock market:
Some companies win just by showing up. Others fight tooth and nail and still lose.
The difference? A sustainable competitive advantage.
In Morningstar’s world, they call this an economic moat.
Let me show you exactly what that means—and how it can help you avoid portfolio landmines.
TLDR: What Is an Economic Moat?
- It’s a company’s ability to maintain long-term profitability and fend off competitors
- Morningstar ranks moats as none, narrow, or wide
- Moats are based on 5 key factors: switching costs, intangible assets, cost advantages, network effects, and efficient scale
- Companies with wide moats often compound returns over decades
- It’s a central part of Morningstar’s valuation and rating system

1. Why the Term “Moat”?
Think medieval castles. A moat protects the castle from invaders.
Same idea here: an economic moat protects a company’s profits from competitors.
Wider the moat? Harder it is for rivals to chip away at market share or pricing power.
And Morningstar analysts evaluate these moats very seriously when deciding whether a company can sustain its edge over the long term.

2. The 5 Moat Sources Morningstar Looks For
1. Switching Costs
When it’s painful or expensive to switch providers, customers tend to stay put. Think enterprise software (like Salesforce).
2. Intangible Assets
Brands, patents, or government licenses that are hard to replicate. Think Coca-Cola or Pfizer.
3. Cost Advantage
Companies that can produce more efficiently than competitors. Think Walmart or Costco.
4. Network Effect
When the product becomes more valuable as more people use it. Think Visa or Meta.
5. Efficient Scale
Some markets are just too small for multiple players. Think utilities or regional airports.
If a company checks one or more of these boxes, it could have a narrow or wide moat.
3. How Morningstar Ranks Moats
- Wide Moat: Strong, sustainable advantage expected to last 20+ years
- Narrow Moat: Some edge, but not guaranteed to endure
- No Moat: No meaningful advantage—expect competition to erode profits
This isn’t opinion. Morningstar backs it up with fundamental analysis, competitive data, and management strategy review.
And yes—moats heavily influence their stock ratings.
