Updated 2026-10-29 · 11 stocks · Scores are Marvin's own

Staffing and employment services companies help businesses find, hire, place and pay workers. This list covers 11 of them that Marvin's rules selected, starting with the highest overall score. Paychex, Korn Ferry and Upwork are at the top.

Results in this industry vary a lot. Some companies here have wide profit margins, while others keep only a thin slice of each sales dollar. Several posted a decline in revenue growth in their last fiscal year, and a few carry a lot of debt compared with their equity.

Keep in mind that a high score is not a promise about the future. It only shows how a company compares with other companies in the same industry today. Where a figure is missing for a stock, the blurb says so.

Common questions

What do staffing and employment services companies do?

They help employers find and hire people. Some place temporary or permanent workers, some run online marketplaces that connect employers with job seekers or freelancers, and some handle payroll and related services for other businesses.

Why are the margins so thin for many of these stocks?

Traditional staffing firms often pay workers' wages out of the money they bill clients, so a large share of revenue goes straight to costs. That leaves a small share as profit, which is why gross and operating margins tend to be lower than at software-style businesses.

What does a high debt-to-equity ratio mean?

It compares what a company owes with the value of its shareholders' stake. A higher ratio means the company relies more on borrowed money, which can add risk if earnings weaken. A low ratio means it relies less on debt.
