Companies grouped by competitive moat mechanism & strategic pillars
Understanding Stock Economic Moats
Competitive advantages, switching costs, and moat rating methodology
What is an economic moat in stock investing? ↓
An economic moat is a company's structural ability to maintain a sustainable competitive advantage over rivals to protect long-term market share and high gross margins. Popularized by Warren Buffett, economic moats allow companies like Palantir ($PLTR), NVIDIA ($NVDA), Meta ($META), and ServiceNow ($NOW) to generate compounding high returns on invested capital.
What are the 7 primary moat archetypes? ↓
• Switching Costs: High operational friction preventing customers from replacing mission-critical software.
• Network Effects: Platform value compounding exponentially with every additional user or developer.
• Ecosystem Lock-in: Tight hardware, software, and API integration creating high user retention.
• Proprietary Data: Exclusive, irreplaceable data loops that continuously train proprietary AI models.
• Cost Advantage: Structural cost efficiencies allowing price leadership while maintaining industry-high margins.
• Infrastructure Lock-in: Physical data center and GPU cluster scale that competitors cannot replicate.
• Efficient Scale: Dominance in a specialized market where adding new competitors dilutes industry returns.
What is the difference between Wide Moat and Narrow Moat? ↓
A Wide Moat rating indicates high-conviction competitive barriers expected to protect excess capital returns for 20+ years. A Narrow Moat rating indicates solid defensibility expected to sustain strong profitability for 10–15 years.
What is the "Rule of 40" in tech stock analysis? ↓
The Rule of 40 is a key efficiency benchmark for software and technology companies. It states that a high-performing tech company's annual Revenue Growth Rate (%) + Profitability Margin (%) (such as FCF margin or EBITDA margin) should equal or exceed 40%. For example, a company with 30% revenue growth and a 15% FCF margin achieves a score of 45%. Sustaining a Rule of 40 score above 40% demonstrates strong pricing power, scalable unit economics, and an effective economic moat.
