About Quantitative Ratings
Morningstar Quantitative Ratings for Stocks are generated using an algorithm that compares companies that are not under analyst coverage to peer companies that do receive analyst-driven ratings. Companies with quantitative ratings are not formally covered by a Morningstar analyst, but are statistically matched to analyst-rated companies, allowing our models to calculate a quantitative moat, fair value, and uncertainty rating.
