Top 20 Medical Stocks Ranked by Marvin Scores

Marvin's rules picked 20 medical stocks across care facilities, devices, diagnostics, health plans and more. Nutex Health, Globus Medical and Quest Diagnostics have the highest overall scores in this list.

Updated 2026-10-22 · 20 stocks · Scores are Marvin's own

Medical stocks cover many kinds of businesses: hospitals and care providers, device makers, lab and diagnostic companies, drug companies, and health insurers. This list has 20 companies from those groups that score well on Marvin's measures.

Marvin's scores compare each company only with others in its own industry. A high score for a care provider and a high score for a device maker do not mean the businesses look alike, so check the figures behind each pick.

Keep in mind that the figures describe the last fiscal year and today's comparison, not what comes next. Some companies have missing data, which the blurbs point out. This is research information, not advice to buy or sell.

Common questions

Does a high Marvin score mean a stock is a good buy?

No. The scores only describe how a company compares with others in its industry today. They are not a prediction and not advice to buy, sell or hold.

Why do some stocks on this list have missing figures?

Not every company reports every measure in a form that can be compared. Insurers and royalty businesses, for example, often do not have a standard gross margin. Where a figure is missing, the blurb says so and relies on the figures that are available.

Why are the scores compared only within an industry?

Different kinds of medical businesses have very different typical margins and debt levels. A health insurer normally has a thinner operating margin than a device maker, so comparing each company with its own industry gives a fairer picture.
