Small-Caps Rally as Iran Deal Fuels Market Rotation
Factor Trends

Small-cap stocks have spent years in the shadow of mega-cap tech, but that dynamic is shifting fast.
The US-Iran peace deal, announced this week, reopened the Strait of Hormuz and sent crude oil to a three-month low.
The S&P 500 jumped 1.7% on Monday, but small-cap indexes hit record highs the same day — a sign that the rotation is already underway.
Smaller companies are generally more exposed to domestic economic conditions than their large-cap peers. Lower fuel costs reduce operating expenses across manufacturing, retail, and logistics — sectors that dominate small-cap indexes.
Nick Kalivas, Invesco's head of factor strategy for exchange-traded funds (ETFs), said lower oil prices can "accelerate the profitability recovery for the small-caps."
Angelo Kourkafas, senior global investment strategist at Edward Jones, framed the macro logic clearly. Easing geopolitical tensions could reduce bond yields, and lower yields historically improve conditions for smaller, more rate-sensitive companies.
"It may be showtime for small-caps."

JPMorgan strategists said they were looking for broadening in the second half of 2026. Cyclicals should remain well-positioned if inflation stays stable and geopolitical risks ease.
Morgan Stanley echoed the view, citing relative strength ahead for consumer discretionary, transport, and regional banks.
Most small-cap funds track the Russell 2000, which includes ~2K companies with no profitability requirements. Hundreds of its constituents are unprofitable, which adds drag in tighter economic conditions.
The S&P SmallCap 600 takes a different approach. To be included, a company must show four consecutive quarters of profits. That quality screen has made a long-term difference.
Over 30 years, the S&P SmallCap 600 has returned 1.7K%. The Russell 2000 returned 1.1K% over the same period.
The Vanguard Russell 2000 ETF tracks the broader index. It is up 13.2% year-to-date through early June and tts 0.06% expense ratio keeps costs low.
If you want the quality filter baked in, the Invesco S&P SmallCap 600 QVM Multi-factor ETF goes further. It starts with the S&P SmallCap 600 and removes the bottom 10% of stocks ranked on quality, value, and momentum each quarter.
Since its June 2021 launch, has outperformed both the S&P SmallCap 600 and the Russell 2000, with an annual expense ratio of just 0.15%.
Beyond the near-term catalyst, the long-term case centers on small-cap value stocks, or smaller companies trading cheaply relative to their fundamentals.
US small-cap value beat the S&P 500 by 39% over the 26 years from 1999 to 2024, according to Vanguard fund data. Outside the US, the premium is even wider. International small-cap value beat the global ex-US market by 99% over 28 years.
Small-cap value ETFs typically allocate 6% to 10% to technology. That compares to over 30% in the MSCI World. The S&P 500's tech allocation runs closer to 40%.
That low-tech tilt provided real insulation during the 2000 dot-com crash, when small-cap value funds rose while the S&P 500 fell 42%.
The trade-off is patience. US small-cap value has beaten the S&P 500 in just two of the past ten years. The strategy is cyclical by nature, so investors should be prepared to ride out the dry spells, ideally for a decade or more.
