Simple answer
The Moat Score estimates the durability of a company's competitive advantage.
Why this matters
A moat protects profits from competition over time.
Good signs
Favorable model inputs can motivate research into an advantage; they do not establish its permanence.
Warning signs
A narrow or absent moat means profits may be competed away.
Easy mistake to make
Overestimating moats in fast-changing industries.
How Wall Street Score helps
Shown as a category in the score breakdown.
Name the advantage and the evidence
A competitive advantage needs a mechanism: lower delivered costs, difficult switching, a valued brand, network benefits or a defensible legal right. State which one is proposed and which company disclosure supports it. High margins alone do not identify the cause.
For example, recurring software revenue is not sufficient proof of switching costs. Investigate customer retention, contract renewal terms, implementation costs and credible alternatives. For a patent-dependent product, check the scope and expiration of relevant rights.
Distinguish pricing power from temporary conditions
Hypothetically, revenue rises from $100 million to $110 million while operating profit rises from $20 million to $25 million. Margin improves from 20% to about 22.7%. That could reflect pricing power, but it could also reflect lower input costs, product mix or temporary cost cuts.
Compare unit volumes, prices and costs where disclosed. Test whether customers stayed after price increases and whether returns persisted through a difficult industry period. Do not infer verified market-share gains from a margin trend.
Write down what could weaken the advantage
Identify a specific counter-case: a cheaper substitute, easier data migration, a new distribution channel, regulation or customer concentration. Track an observable indicator such as renewal rates or unit economics rather than relying only on a score change.
The Moat Score is a model output, not a forecast of how long an advantage will last. Avoid adding confidence merely because several scores share similar inputs. Even a durable business can produce poor investment returns if the purchase price assumes too much growth.
