Why this topic matters
An economic moat is a metaphor for a business defense that competitors may find difficult to copy. Brand, network effects, scale, switching costs, or unique assets can support customer retention and pricing power.
A practical review order
Test the story against durable numbers. Review multi-year margins, customer retention, repeat use, and how the company protects prices and costs when competition increases.
Common mistakes to avoid
A patent or market-share lead does not guarantee a lasting barrier. Note expiration, regulation, technology substitution, customer concentration, and the pace of competitor investment.
Key takeaway
