Updated 2026-11-02 · 11 stocks · Scores are Marvin's own

Data and stock exchange companies run the marketplaces where securities trade, or sell the ratings, indexes and data investors use to make decisions. This list covers 11 companies in that industry, ordered by Marvin's Overall score.

Look at more than the order. Some companies rank high because their business is strong. Others rank high because Marvin's Opportunity score is high. The Quality and Opportunity scores in each blurb show which is the case.

Some figures are missing for certain companies, such as debt or free cash flow. A missing figure means less is known, not that the result is good or bad. This is research, not advice.

Common questions

What do data and stock exchange companies do?

They run the marketplaces where securities are traded, or they sell data, ratings, indexes and analytics that investors and institutions use. Companies in this industry can differ a lot, so compare each one's figures.

Why can a company have a high Quality score but a low Overall score?

Overall combines Quality and Opportunity. S&P Global has a Quality score of 78 but an Opportunity score of 16, so its Overall score is 40. Read both scores.

Does a high ranking mean I should buy the stock?

No. The ranking only shows how a company compares with others in its industry today, using the data available. It is not a recommendation or a prediction. Do your own research before investing.
