Morningstar developed the Morningstar Equity Comparables system to give investors and financial professionals an objective benchmark for comparing companies. Morningstar Equity Comparables is genuinely different to other industry classification schemes. We start from the bottom up with comparable companies, as opposed to the top down with sector definitions. For every pair of companies, we determine how similar they are–anywhere from closely comparable to distantly related based on automated analysis of the companies' own business description. We automatically analyse the text of the business description and work out whether companies are talking about similar things as they describe their businesses. Businesses described in similar terms are comparable.
