Imagine two companies sell the exact same product at the exact same price. If a rival can enter tomorrow and match them feature-for-feature, neither one has a moat — profits get competed away over time. A moat is whatever makes that hard: a brand people trust blindly (think Eicher's Royal Enfield), a cost advantage rivals can't match (DMart's owned real estate keeping prices lowest in the industry), a network that gets stronger with more users (a bank's branch network, a telecom's tower grid), or switching costs that make customers reluctant to leave. When you see a high Moat score on one of our scorecards, it means the business isn't just doing well right now — it has a structural reason to keep doing well even if competitors try to copy it.
