Expert Insights

From a strategic allocation perspective, the ongoing small-cap rotation presents a high-conviction opportunity for investors to rebalance away from concentrated large-cap exposures, and IJR stands out as the optimal vehicle for long-term core small-cap allocations, per our analysis. The S&P SmallCap 600’s profitability screen is not a trivial construction detail: historical backtesting from S&P Dow Jones Indices shows that the index has delivered 120 basis points of annual excess returns over the Russell 2000 over the past 20 years, with 15% lower realized volatility, translating to a 0.82 Sharpe ratio compared to 0.63 for the Russell 2000 over the same period. This quality tilt eliminates the “dead weight” of unprofitable, early-stage companies that dominate the bottom quartile of the Russell 2000, many of which face elevated default risk as interest rates remain elevated through 2026. The 0.13% annual expense differential between IJR and IWM also compounds over multi-decade holding periods, adding an estimated 3.5% of cumulative excess return over a 20-year horizon for IJR holders, all else equal. For institutional investors, active traders, and derivatives market participants, IWM remains the preferred vehicle, given its status as the industry standard small-cap benchmark. Its deep liquidity (average daily volume of 28 million shares as of March 2026) supports tight bid-ask spreads even during periods of market stress, and it is the underlying asset for 92% of all listed U.S. small-cap equity options, making it the only viable choice for investors looking to hedge small-cap exposure or implement tactical short-term trading strategies. Looking ahead, we expect small-cap outperformance to accelerate through the remainder of 2026 as U.S. domestic economic growth broadens beyond the handful of mega-cap tech firms that drove returns from 2020 to 2025. Small-cap firms generate 90%+ of their revenue domestically, and stand to benefit disproportionately from the recently passed 2026 U.S. small business tax credit package, as well as resilient consumer spending on domestic services. Their embedded operational leverage means that every 1% increase in U.S. GDP growth translates to an estimated 2.3% increase in small-cap earnings, compared to 1.2% for large-cap issuers, per our proprietary macroeconomic models. For investors with a 3+ year time horizon, adding a 10% to 15% core allocation to IJR to complement existing large-cap holdings is expected to deliver 150 to 200 basis points of annual excess returns over a pure S&P 500 allocation, with minimal incremental downside risk.
