Economic Moats & Competitive Advantage
Identifying companies with durable competitive advantages.
An economic moat is a sustainable competitive advantage that allows a company to protect its market share and profits from competitors over the long term. The term was popularized by Warren Buffett.
Types of moats
1. Brand Power — Customers choose the brand even when cheaper alternatives exist (Apple, Coca-Cola, Nike). Shows up as premium pricing and high margins.
2. Switching Costs — It is expensive or painful for customers to switch to a competitor (Microsoft Office, enterprise software, banks). Leads to sticky, recurring revenue.
3. Network Effects — The service becomes more valuable as more people use it (Meta, LinkedIn, payment networks). Creates winner-take-most dynamics.
4. Cost Advantage — The company can produce at lower cost than competitors (Walmart, Costco, Ryanair). Enables lower prices or higher margins.
5. Intangible Assets — Patents, regulatory licenses, proprietary technology (pharmaceutical companies, utilities). Provides legal protection from competition.
6. Efficient Scale — A market that only supports one or a few profitable players (railroads, utilities, airports). New entrants are deterred because the market can't support them.
How to spot moats in the data
On MetricSide, moat signals show up in the fundamentals: - High, stable margins (Operating Margin, Net Margin) → Pricing power - High, consistent ROE (15%+) → Capital-efficient business model - Consistent FCF generation → Capital-light operations - Steady revenue growth → Durable demand
MetricSide's Moat Signals section on the Overview page analyzes these factors automatically across 8 quarters of data.
Beware of false moats
Not every successful company has a moat. Companies in cyclical industries (energy, materials) may show strong numbers in good times but lack durable advantages. Look for consistency across multiple years and economic cycles.
