Marvin's rules picked 20 profitable defensive stocks across Healthcare, Utilities and Consumer Defensive. They are ranked by Business Quality, with each company scored against others in its own industry.

Updated 2026-10-18 · 20 stocks · Scores are Marvin's own

Defensive stocks come from areas people keep spending on in good times and bad, such as healthcare, electricity and water, and everyday household and food products. Their businesses tend to be steadier than those of companies that depend on the economy's ups and downs. Steadier does not mean risk-free.

This list has 20 profitable companies from Healthcare, Utilities and Consumer Defensive. Each one passed Marvin's rules for size, profitability and overall score. Healthcare makes up most of the list, with a few utilities and consumer staples among them.

When you read the picks, look at the figures together. Strong margins suggest a company keeps more of each sale as profit, and a low debt-to-equity ratio suggests it leans less on borrowing. Some figures are missing for some companies, and each blurb notes where that matters.

Common questions

What makes a stock defensive?

A defensive stock belongs to a business people keep paying for in any economy, such as healthcare, power and water, or household staples. Its sales tend to be steadier than those of companies selling things people can delay buying. That steadiness is a tendency, not a guarantee, and defensive stocks can still fall.

Why are so many of these stocks in Healthcare?

Marvin's rules look at three sectors: Consumer Defensive, Utilities and Healthcare. They then rank companies by Business Quality, so the order reflects how strong each company's finances look against its industry peers. A lot of healthcare companies scored well on that measure, which is why the sector makes up most of the list.

What do Marvin's scores mean?

Overall, Quality and Opportunity scores run on a scale from zero to one hundred and compare a company only with others in its own industry. A high score means the company looks strong relative to its peers today. The scores are not predictions or advice, and a company's score can change as new financial results arrive.
