Overview
IJH and IJR are core equity index ETFs from iShares that track different tiers of the U.S. Both launched on the same day and carry minimal fees, but they differ in the size and volatility profile of their holdings and in yield.
How they differ
The fundamental difference is market capitalization exposure: IJH holds mid-cap companies (generally $10B–$50B in market cap), while IJR targets small-caps ($2B–$10B). That size difference drives their second-order distinction — IJR carries a higher beta of 1.07 versus IJH's 1.0, signaling greater price sensitivity to market swings. Expense ratios are nearly identical — 0.05% for IJH and 0.06% for IJR — making fees a negligible factor in the decision.
Who each is best for
IJH: Fits investors seeking broad U.S. equity exposure with moderate growth potential and lower volatility than smaller stocks. Mid-cap balance appeals to those rotating capital into steadier equities while retaining upside participation.
IJR: Fits investors comfortable with higher volatility in exchange for greater long-term capital appreciation potential. Small-cap tilt suits those with extended time horizons and tolerance for wider drawdowns during market corrections.
Key risks to know
- Market-cap reversion risk: Small-caps and mid-caps experience materially different performance cycles. IJR may underperform during periods when large-cap stocks dominate; IJH may lag when investors chase smaller, faster-growing names. No guarantee these funds will deliver similar returns over any given horizon.
- Beta and drawdown volatility: IJR's 1.07 beta implies roughly 7% more price swings than the broad market. Mid-cap's 1.0 beta suggests closer alignment to market moves. During equity selloffs, IJR typically declines more sharply than IJH.
- Liquidity and corporate action exposure: Smaller-cap holdings are more vulnerable to individual company credit events, restructurings, and lower trading volumes. IJH's larger constituents typically have wider analyst coverage and tighter bid-ask spreads.
Bottom line
If you want steady market-aligned exposure with less volatility, IJH's mid-cap tilt offers simplicity and lower price swings. If you're willing to tolerate higher beta and are investing over a long horizon, IJR's small-cap exposure may deliver stronger total returns, though past performance does not predict future results.
