Overview
IJR and VB are both broad small-cap equity ETFs tracking slightly different universes of U.S. companies under $10 billion in market value. IJR tracks the S&P SmallCap 600 Index, while VB uses the CRSP US Small Cap Index, which is roughly twice as large and includes more names. Both deliver identical distribution rates and quarterly payouts, but differ in expense ratio, issuer, and underlying index composition—a distinction that matters for overlap and sector weightings.
How they differ
The core difference is index methodology: IJR holds 600 stocks by design, while VB's CRSP index encompasses around 1,400 names, giving VB broader exposure to the micro-cap end of small-cap. VB carries a slightly lower expense ratio at 0.05% versus IJR's 0.06%—a narrow gap that widens only on larger positions. Both distribute 1.15% annually in quarterly chunks, so yield is identical. VB is also slightly smaller by AUM ($82.5B vs. $113B); IJR launched in 2000 while VB arrived in 2004, which may explain some of the asset sizing difference.
Who each is best for
IJR: Fits investors seeking a tighter, more focused small-cap portfolio weighted toward established names within the small-cap tier, with the reassurance of a 23-year track record and the iShares ecosystem.
VB: Designed for investors who want broader exposure across the entire small-cap and micro-cap spectrum, including smaller, less-liquid names that IJR's narrower index excludes.
Key risks to know
- Index overlap and performance divergence. Both funds track different slices of small-cap, so their sector and company overlap may vary. A tilt toward a particular small-cap cohort (e.g., growth vs. value, or highly liquid vs. thinly traded names) could cause meaningful performance gaps over time.
- Small-cap volatility and liquidity. IJR's beta of 1.07 and VB's beta of 1.1 both confirm higher volatility than the broad market. Smaller companies are more sensitive to interest-rate and credit-cycle swings, and during liquidity crunches, the less-liquid names in VB's broader index may face wider bid-ask spreads.
- Concentration within the index. While both funds hold dozens or hundreds of names, small-cap indices are often dominated by a handful of larger small-cap names. A sharp drawdown in that cohort affects both funds, though the distribution of holdings may differ.
- Reinvestment and tax drag. Quarterly distributions mean reinvestment timing risk; if small-cap rallies sharply within weeks of a distribution, reinvested capital may buy into a dip.
Bottom line
Both ETFs offer lean, broad access to U.S. small caps with minimal fees and identical yields. IJR's narrower index and longer track record suit investors drawn to a more concentrated, established approach; VB's wider universe and marginally lower expense ratio appeal to those prioritizing deeper micro-cap representation.
