Questions
The Moat Index is MoatDefender’s dated opinion on competitive defensibility. A reading carries a range, a band, confidence, method version and date. Read the supporting evidence and limits alongside the number.
Read the published principlesLink to this questionInvestors use the Moat Index to examine competitive defensibility beside the available evidence. The seven Powers provide established vocabulary for several types of advantage. Investors still need independent commercial, financial and legal diligence.
Read the investor guideLink to this questionBuilders use MoatDefender to examine an advantage and choose the next evidence to collect. Moat Studio records the work and its current status. A proposed action does not establish that a barrier has strengthened.
Read the Studio guideLink to this questionMoatDefender does not independently verify every business claim in a reading. A cited source still requires examination for relevance, date and limits. Certification means methodology verification only and does not establish investment quality.
