Expert Insights

“The prolonged small-cap underperformance over the past half-decade has been almost entirely driven by earnings differentials, not just investor sentiment,” notes independent equity strategist David Dierking. He adds that the S&P 500’s 10 consecutive quarters of positive year-over-year earnings growth, including five straight quarters of double-digit expansion, created a wide performance moat relative to small caps, which faced disproportionate headwinds from higher interest rates, tighter credit conditions, and greater exposure to cyclical domestic end markets between 2022 and 2024. While small caps typically trade at a 10% to 15% discount to large caps due to higher volatility, lower liquidity, and elevated business risk, the current 36% discount sits 2 standard deviations below the 20-year average, per YCharts data. This dislocation is particularly notable given converging earnings growth trajectories: the S&P 600 is currently trading at a 0.8x price-to-earnings-growth (PEG) ratio, versus 2.0x for the S&P 500, a rare value signal that has preceded 20%+ average small-cap outperformance over 2-year holding periods in prior market cycles dating back to 1990. Admittedly, upside for IJR is not without risk. Potential headwinds include downside surprises to U.S. domestic GDP growth, unexpected Federal Reserve rate hikes, and credit spread widening that could disproportionately impact smaller firms with higher floating-rate debt exposure. However, recent macro data pointing to cooling core inflation and three expected 25-basis-point Fed rate cuts in 2026 should alleviate much of the interest rate pressure that weighed on small caps over the 2022 to 2024 period. Dierking notes that while it is unlikely small caps will trade at parity with large-cap multiples in the near term, even a reversion to the 20-year average 12% discount would drive a ~22% uplift to IJR’s valuation even before accounting for projected earnings growth. “For investors with a 2 to 3 year time horizon, the risk-reward profile for small caps as represented by IJR is far more compelling than large-cap equities at current levels,” he adds, noting that the segment also offers meaningful diversification benefits for portfolios heavily weighted to crowded megacap tech positions. iShares Core S&P Small-Cap ETF (IJR) - Impending Earnings Inflection Signals Multiyear Small-Cap Outperformance PotentialMonitoring commodity prices can provide insight into sector performance.
