Frequently Asked Questions
What makes a stock a 'wide moat' stock?
A wide-moat stock belongs to a business with a durable competitive advantage — brand, network effects, cost leadership, switching costs, or regulatory protection — that lets it earn above-average returns on capital for many years. ValueOS scores this with the same moat framework Buffett uses.
How is the widest moat ranking built?
We run every stock in our universe through the Moat Analyzer model at build time, rank by moat strength (Wide > Narrow > None) and then by overall quality score, and surface the top 25. Each links to its live Score, Moat, and DCF pages.
Are wide moat stocks always cheap?
Not necessarily. A wide moat tells you about durability, not price. Pair this list with our Margin of Safety and Undervalued Quality rankings to find moats trading below intrinsic value.
