Key Takeaways
- • The Invesco S&P SmallCap Information Tech ETF (PSCT.O) has attracted $49.7 million in inflows year-to-date in 2026, reversing four consecutive years of outflows as investors shift capital toward smaller AI-exposed technology companies.
- • The S&P 600 small-cap tech index has surged 54% year-to-date, compared with a 20.1% gain in the broader S&P 500 technology index, creating the widest performance gap between the two benchmarks since before 1995.
- • Small-cap technology stocks including MaxLinear and VIAVI have posted triple-digit gains this year, driven by improving earnings prospects, relatively cheap valuations, and exposure to AI infrastructure buildout (chipmakers, data center suppliers, and network equipment makers).
- • Portfolio managers cite broadening AI adoption beyond megacap names, with Lazard's Oren Shiran noting that "small-caps have become a real part of the second and third order of AI," capturing exposure to downstream beneficiaries of AI infrastructure development.
- • Despite strong fundamentals, some analysts warn the rally carries speculative characteristics, with concerns about an AI bubble potentially inflating small-cap valuations to record highs.
Summary
U.S. small-cap technology stocks are experiencing a sustained rally after years of underperformance, as institutional and sophisticated investors broaden their AI exposure beyond established megacap leaders like Nvidia and Intel. The shift reflects a fundamental reorientation in how the market views artificial intelligence as an investment theme—not limited to core chipmakers, but extending across an entire ecosystem of enabling technologies and infrastructure providers.
The Invesco S&P SmallCap Information Tech ETF (PSCT.O) has captured this trend meaningfully, recording $49.7 million in inflows through May 2026 after suffering outflows in each of the four prior years. This reversal signals genuine institutional appetite for smaller-cap exposure. Performance metrics underscore the magnitude of the move: the S&P 600 small-cap technology index has gained 54% year-to-date, compared with 20.1% for the broader S&P 500 technology index. According to Trivariate Research, the performance spread between the two indices is at its widest level since before 1995, indicating historically outsized small-cap strength relative to large-cap peers.
Individual stocks exemplify the rallies underway. MaxLinear and VIAVI have posted triple-digit gains in 2026, benefiting from investor recognition of their roles in AI infrastructure and related buildout. Portfolio managers cite multiple drivers: improving earnings prospects among smaller firms, valuations that remain relatively attractive compared with megacap peers, and diversified exposure across chipmakers, data center suppliers, and network equipment manufacturers—all integral to AI deployment at scale.
Oren Shiran, portfolio manager for Lazard US Systematic Small Cap Equity ETF, framed the dynamic as a broadening thesis: "The AI trade has broadened quite materially. Small-caps have become a real part of the second and third order of AI." This language captures how the investment community now views small-cap technology not as tangential to AI, but as core beneficiaries of downstream infrastructure demand.
However, the strength of 2026's technology rally—both large-cap and small-cap—has prompted cautionary commentary. Some analysts warn that speculative positioning may be amplifying small-cap gains to record highs, and discussions of an AI bubble have intensified. The distinction between fundamental earnings growth and speculative momentum remains contested, warranting careful due diligence on individual names and sector exposure sizing.
