Top 15 Small-Cap Industrials Stocks by Marvin Score
Marvin's rules picked 15 small-cap Industrials stocks, led by Pangaea Logistics, Douglas Dynamics and American Superconductor. Each is ranked by Overall score against companies in its own industry.
Small-cap Industrials companies make things, move things or provide services to other businesses, and they are smaller than the big household names in the sector. This list shows 15 of them that Marvin's rules ranked highest on Overall score as of 2026-11-02.
Small companies can swing more from year to year than large ones, so one strong figure rarely tells the whole story. Look at growth, profit margins and debt together, and note where a figure is missing.
Marvin's scores only describe how a company compares with others in its industry today. They are not a forecast and not a recommendation.
The list

Marvin started with Industrials companies above a minimum size and below a small-cap ceiling, then ranked them by Overall score, highest first, with at most four companies from any one industry. Scores run on a scale of zero to one hundred and are relative to each company's own industry, so a high score means a company looks strong compared with its industry peers, not compared with every stock.

The stocks, one by one
Pangaea Logistics Solutions, Ltd. PANL
This marine shipping company holds a top Overall score of 96. Revenue growth was 17.8% and debt-to-equity is 0.55, which suggests solid expansion with moderate borrowing. Caution: operating margin of 9.3% is fairly slim, and free cash flow margin is not available.
Douglas Dynamics, Inc. PLOW
Douglas Dynamics, a machinery maker, posts an Overall score of 96 with revenue growth of 15.4% and return on equity of 17.5%, pointing to healthy expansion and decent profit on shareholder capital. Caution: free cash flow margin of 7.0% is modest, and debt data is missing.
American Superconductor Corporation AMSC
American Superconductor shows fast revenue growth of 34.3% and return on equity of 23.9%, along with a Quality score of 87. Caution: its operating margin of 4.9% is thin, so little of each sales dollar becomes operating profit.
Global Industrial Co GIC
Global Industrial, a distributor, has return on equity of 25.4% and gross margin of 36.4%, plus a Quality score of 86. Caution: revenue growth of 4.8% is modest, so its strength lies in profitability rather than fast expansion.
National Presto Industries, Inc. NPK
National Presto, in aerospace and defense, grew revenue 29.7% and has an Opportunity score of 96. Operating margin is 9.6%. Caution: gross margin of 16.5% is low and return on equity of 10.4% is middling.
Park Aerospace Corp. PKE
Park Aerospace stands out for profitability: operating margin of 21.1% and free cash flow margin of 14.2% are strong. Revenue growth was 18.2%. Caution: return on equity of 9.1% is fairly low, and its Opportunity score is only 78.
Resolute Holdings Management, Inc. RHLD
Resolute Holdings has gross margin of 40.9% and free cash flow margin of 7.2%, with revenue growth of 9.9%. That suggests decent cash generation and steady growth. Caution: return on equity and debt figures are not available, so the picture is incomplete.

Smith & Wesson Brands, Inc. SWBI
Smith & Wesson turns sales into cash well, with free cash flow margin of 14.9% and revenue growth of 10.4%. Caution: operating margin of 6.6% and return on equity of 6.6% are both low, so profits are modest.
Napco Security Technologies, Inc. NSSC
Napco Security is highly profitable, with gross margin of 59.2%, free cash flow margin of 29.3% and a Quality score of 94. Caution: its Opportunity score of 28 is well below its Overall score.
Paysign, Inc. PAYS
Paysign has fast revenue growth of 40.5%, free cash flow margin of 73.0% and low debt-to-equity of 0.18, a strong mix of growth and cash. Caution: a margin this high may not be typical, and a single year's figures can mislead.
Ennis, Inc. EBF
Ennis has operating margin of 13.6% and free cash flow margin of 14.5%, which are healthy. Caution: revenue growth of -0.6% means sales shrank slightly, and its Quality score of 58 is among the lower ones on this list.
Willdan Group, Inc. WLDN
Willdan Group, an engineering and construction firm, has revenue growth of 20.5%, return on equity of 18.6% and low debt-to-equity of 0.25. Caution: operating margin of 7.1% is thin, so profits can be sensitive to cost changes.

LSI Industries grew revenue 20.2%, but profitability is thin: operating margin of 5.6% and return on equity of 6.3% are low. Caution: debt-to-equity of 0.85 is the highest among the stocks on this list that have debt data.
Common questions
What does small-cap mean?
Small-cap refers to companies with a relatively small total market value compared with the largest listed companies. For this list, Marvin used a minimum size and a ceiling to keep the group to smaller Industrials companies.
Are small-cap stocks riskier than large-cap stocks?
They often are. Smaller companies can have less diversified businesses, thinner finances and bigger swings in results and share price. That is why it helps to check growth, margins and debt together rather than relying on one number.
What do Marvin's Overall, Quality and Opportunity scores mean?
They compare a company with others in its own industry today. Overall is the combined score, Quality reflects the strength of the business, and Opportunity reflects how attractive Marvin's rules find the company's current setup. They are descriptions, not predictions.
