Small-cap stocks have quietly been building a case that the broader market is finally paying attention to. iShares Russell 2000 ETF (NYSEARCA: IWM) is up 5.4% year-to-date, and per Reddit’s investing communities, small caps just extended their outperformance streak against the S&P 500 to 8 consecutive days, the longest such run since 2019. The four stocks below were ranked on revenue growth, earnings beat magnitude, margin expansion, forward outlook, and balance sheet trajectory.
4. Select Water Solutions
Select Water Solutions (NYSE: WTTR) earns the fourth spot because near-term fundamentals remain under pressure despite a strong price move. Q3 2025 revenue came in at $322.2 million, down 13.2% year-over-year and 11.5% sequentially. Net income fell to $2.3 million from $18.8 million a year earlier, and operating income came in at $1.9 million. Free cash flow was −$23.5 million, driven by capital expenditures of $91.1 million as the company builds out infrastructure.
The spending is purposeful: Chemical Technologies revenue rose 13% sequentially to $76.6 million, management guided for 10% Water Infrastructure growth in Q4 and adjusted EBITDA of $60 to $64 million, and the company broke ground on Texas’s first commercial produced water lithium extraction facility. The stock is up 29.9% year-to-date, with a consensus analyst target of $17.30, above the current trading price.
3. Gorman-Rupp
Gorman-Rupp (NYSE: GRC) is a pump manufacturer with one of the more compelling small-cap fundamental stories of the past year. Full-year 2025 net sales reached a record $682.4 million, up 3.4% year-over-year, with record net income of $53.0 million and adjusted EPS of $2.14, a 22% increase. Q4 adjusted EPS of $0.55 beat the $0.47 estimate by roughly 17%, though revenue of $166.6 million came in slightly below the $169.6 million estimate.
Fire suppression, industrial, and OEM pump segments are all seeing uplift from the surge in data center builds. The company ended 2025 with a backlog of $244 million, up 18.4% from $206 million a year earlier, record incoming orders of $728.4 million, up 10.5%, and paid down $60 million in debt. The stock has gained 34.5% year-to-date.
2. Evolv Technologies
Evolv Technologies (NASDAQ: EVLV) is an AI-powered security screening company that posted striking growth last quarter. Q3 2025 revenue came in at $42.9 million, beating the $33.7 million consensus estimate by 27.4% and growing 57% year-over-year. The net loss narrowed dramatically, falling to $1.8 million from $30.4 million in Q3 2024, a 94% improvement, while adjusted EBITDA swung to positive $5.1 million from a loss of $3.0 million. Annual recurring revenue reached $117.2 million, up 25% year-over-year, across a customer base of over 1,000 organizations. Management raised full-year 2025 revenue guidance to $142 to $145 million, representing 37% to 40% growth.
The stock is down 26.0% year-to-date despite the operational progress, with a consensus analyst target of $9.88, above the current trading price. One risk to monitor: a director executed three sales between December 2025 and February 2026 at progressively lower prices.
1. Wolverine World Wide
Wolverine World Wide (NYSE: WWW) reported Q4 2025 results on February 26, 2026, that were solid by almost any measure. Revenue of $517.5 million narrowly beat the $512.9 million estimate, while growing 4.6% year-over-year. Adjusted EPS of $0.45 topped the $0.44. Gross margin expanded 340 basis points to 47.0%, operating income surged 148%, and net income rose 36% to $32.5 million.
Growth was broad-based: Saucony grew 26.4% in Q4 to $125.9 million, Merrell rose 5.9% to $173.1 million, and Sweaty Betty added 8.8%. Full year 2025 net income reached $101 million, more than doubling year-over-year, with free cash flow of $125.5 million. The balance sheet improved materially: cash rose 94% to $206.3 million while total liabilities fell 5.7%, and the company has $135 million remaining on its share repurchase authorization. Insider activity is notable: the CEO acquired over 152,000 common shares in a six-day window in early February, joined by coordinated buying across the CFO, division presidents, and other senior executives. For 2026, management guided for revenue of $1.96 billion to $1.99 billion and adjusted EPS of $1.35 to $1.50, with tariff headwinds as the primary known risk.
Small-Cap Rotation With Substance
The IWM’s outperformance streak is the kind of macro tide that lifts many names indiscriminately. What separates these four is that each has a fundamental catalyst anchoring the move. Gorman-Rupp’s record backlog, Evolv’s explosive revenue growth, and Wolverine’s across-the-board Q4 beat all reflect companies where the operational story is doing real work alongside the macro tailwind. Select Water is the more speculative entry, with upside tied more to a recovery thesis than demonstrated results. Wolverine posted the strongest combination of metrics across the ranking criteria: a large earnings beat, broad brand growth, balance sheet improvement, and notable insider buying activity in the weeks before results.
