Expert Insights

The long-running underperformance of U.S. small-cap equities over the past decade has been driven by two core structural factors: the concentrated earnings power of megacap tech firms, which have accounted for more than 70% of S&P 500 total returns since 2020, and the persistent earnings gap between large and small-cap firms amid rising interest rates and supply chain disruptions. For most of the 2021-2025 period, the wide valuation discount between IJR and large-cap benchmarks was fundamentally justified, as small-cap firms struggled with higher floating-rate debt costs and weaker operating leverage relative to their larger, more geographically diversified peers. That narrative is now shifting. While we do not expect small caps to trade at parity with large-cap P/E multiples in the near term, given their higher inherent volatility and elevated default risk relative to large-cap firms, the current 36% discount is well outside the 15-25% historical average range observed when small and large caps deliver comparable earnings growth. If IJR hits its 29% Q4 2026 earnings growth target, the ETF’s forward P/E ratio would contract to just 14x, making the segment even more attractive for both value and growth-oriented investors. It is critical to acknowledge near-term risks: a resurgence in core inflation that forces the U.S. Federal Reserve to delay expected rate cuts could disproportionately pressure small-cap firms, which carry 2.3x more floating-rate debt as a share of total debt than S&P 500 firms, per Federal Reserve data. However, consensus macro forecasts point to three 25 basis point rate cuts in 2026, which would reduce small-cap interest expenses by an estimated 3-5% in 2027, providing an additional tailwind to earnings growth. For investors with a 2-3 year time horizon, IJR offers a compelling risk-reward profile: we estimate upside of 30-40% for the ETF if the valuation discount contracts to the 20% historical average, even as large-cap returns are muted by stretched valuations. We maintain a bullish outlook on U.S. small caps, with IJR as our preferred low-cost, liquid vehicle for broad exposure to the segment.
