Small-cap tech stocks have delivered respectable returns over the past three years, though they’ve significantly trailed their large-cap counterparts. A good proxy for the group, the Invesco S&P SmallCap Information Technology ETF (PSCT), has posted annualized total returns of around 14%–14.5% through late 2025, a solid performance considering the impact of 2022’s rate hikes and tighter funding conditions.

However, large-cap tech has performed on an entirely different scale. The iShares U.S. Technology ETF (IYW), representing mega-cap names, has compounded at roughly 39% annually over the same period, according to BlackRock. A recent update from Polar Capital quantifies this disparity: their data show that small-cap tech (Russell 2000 Technology) underperformed large-cap tech (Russell 1000 Technology) by 63 percentage points over three years and 116 points over five, on a cumulative basis.

Valuation metrics suggest broader structural challenges. The CFA Institute and Wellington both note that U.S. small caps currently trade at a 25%–30% forward P/E discount to large caps: near multi-decade lows. According to Reuters, small caps now represent just ~1.2% of total U.S. market cap, approaching a 100-year low, while an uptick in reverse splits further signals stress across the segment.

Going forward, valuations and positioning reflect considerable investor caution. Should interest rates stabilize and AI-related investment broaden beyond a small set of dominant firms, historical patterns suggest the potential for a reversal in small-cap relative performance. That said, such catch-up phases are conditional, not guaranteed.

While the overall picture for small-cap tech doesn’t look good, there were a handful of performers over the past three years, which we have listed below.

10. Similarweb Ltd. (NYSE:SMWB)

3Y CAGR: 15.21%

Market Cap: $666.09 Million

Number of Hedge Fund Holders: 17

Similarweb Ltd. (NYSE:SMWB) is one of the best‑performing small‑cap tech names over the past few years, and its latest developments caught renewed analyst interest.

On November 17, Needham & Company LLC reiterated a “Buy” rating on Similarweb, with a price target of $14.00. Their bullish stance was driven by what they called a substantial “large language model (LLM) data opportunity,” which they estimate could become a near‑$1 billion revenue stream over time. Needham also pointed to improved go‑to‑market execution and early signs of better customer retention, which may boost revenue retention metrics heading into fiscal 2026.

This rating came just days after the company’s Q3 2025 earnings (released Nov 11), in which Similarweb reported EPS of $0.05, beating consensus of $0.02, while generating $71.79 million in revenue, just shy of the ~$71.95 million analysts expected.

Still, the quarter was marked by a negative net margin of –11.2% and a negative return on equity of –78.25%, underscoring that profitability remains elusive even as top‑line and per‑share metrics slightly beat expectations.
