Overview
IJH and IJR are both iShares core equity ETFs tracking broad US market-cap segments below the large-cap threshold. IJH provides exposure to the S&P MidCap 400 Index (400 mid-sized companies), while IJR tracks the S&P SmallCap 600 Index (600 smaller companies). The funds are nearly identical in structure and cost, but differ in the size of companies they hold and the volatility profile that comes with it.
How they differ
The most obvious difference is the underlying index: IJH holds mid-cap stocks (market cap roughly $2B–$10B range), while IJR holds small-caps ($300M–$2B range). This size difference is the primary driver of IJR's higher beta of 1.08 versus IJH's 1.0, meaning IJR tends to swing more sharply in both directions than the overall market. IJR also offers a slightly higher distribution rate of 1.19% compared to IJH's 1.00%, reflecting small-cap earnings yields; both pay quarterly. The expense ratios are nearly identical—IJH charges 0.05% and IJR 0.06%—so fees are not a meaningful differentiator. IJH holds a larger asset base at $118B versus IJR's $103B.
Who each is best for
IJH: Fits investors seeking mid-cap equity exposure with moderate growth and income characteristics, wanting a middle ground between large-cap stability and small-cap volatility.
IJR: Fits investors comfortable with higher price swings in exchange for small-cap growth potential and a modestly higher yield, typically those with longer time horizons and higher risk tolerance.
Key risks to know
- Small-cap liquidity and trading cost (IJR-specific). Smaller companies in the SmallCap 600 index generally trade with wider bid-ask spreads than mid-caps, potentially increasing execution cost when buying or selling larger positions.
- Higher beta volatility (IJR-specific). IJR's 1.08 beta means it will likely decline more steeply during market downturns and rally more aggressively in upturns. This amplified price swings may create emotional pressure to buy or sell at inopportune times.
- Mid-cap transition risk (IJH-specific). As companies grow and move in or out of the mid-cap range into large-cap indices, IJH experiences periodic rebalancing. Rapid upward migration of large holdings can occasionally create subtle drag.
- Earnings sensitivity. Both funds hold companies with shorter earnings histories and smaller analyst coverage than large-caps. Economic slowdowns or interest rate spikes can disproportionately impact profitability in this size range.
Bottom line
If you want lower volatility and a simpler hold with minimal tracking costs, IJH's mid-cap exposure and 1.0 beta match that goal. If you're willing to tolerate higher swings for small-cap growth potential and a 19 basis-point higher yield, IJR's risk-return profile aligns with that appetite. Both are cheaply run and highly liquid; the choice hinges on how much market volatility you can manage and what company size range fits your growth expectations.
