The Vanguard Small-Cap ETF (VB +0.14%) and iShares Core S&P Small-Cap ETF (IJR 0.72%) both offer broad, low-cost small-cap U.S. stock exposure, but differ in sector tilts, number of holdings, and minor differences in cost and recent returns.
Both VB and IJR are designed for investors seeking diversified access to U.S. small-cap equities, tracking slightly different indexes and offering ultra-low fees. This comparison unpacks how these subtle distinctions play out in cost, composition, performance, and risk.
Snapshot (cost & size)
| Metric | VB | IJR |
|---|---|---|
| Issuer | Vanguard | IShares |
| Expense ratio | 0.03% | 0.06% |
| 1-yr return (as of 2026-03-11) | 20.1% | 18.9% |
| Dividend yield | 1.3% | 1.4% |
| Beta | 1.07 | 1.04 |
| AUM | $169.1 billion | $92.2 billion |
Beta measures price volatility relative to the S&P 500; beta is calculated from five-year monthly returns. The 1-yr return represents total return over the trailing 12 months.
VB is slightly more affordable with a 0.03% expense ratio, compared to IJR’s 0.06%. Yield is nearly a wash, but IJR edges ahead by 0.1 percentage points, offering a marginally higher payout.
Performance & risk comparison
| Metric | VB | IJR |
|---|---|---|
| Max drawdown (5 y) | -28.16% | -28.02% |
| Growth of $1,000 over 5 years | $1,204 | $1,083 |
Performance and risk are tightly aligned: both funds experienced similar maximum drawdowns over the past five years, but VB delivered stronger five-year growth of $1,204 on a $1,000 investment, versus $1,083 for IJR. This difference likely reflects index construction nuances and sector tilts, rather than meaningful divergence in strategy or risk profile.

What this means for investors
These two ETFs cover slightly different ground within the small-cap universe. The Vanguard ETF tracks the CRSP US Small Cap Index, which includes around 1,317 small-cap stocks. It basically covers the same ground as the Russell 2000 up to a point, as it leaves off the smallest 700 or so microcap stocks.
The iShares ETF tracks a more selective portion of the small-cap universe, specifically, the S&P SmallCap 600. This index focuses only on small-cap stocks that are profitable, and have met certain screens to ensure that they trade frequently enough.
The Vanguard ETF has consistently been the better performer of the two, with a one-year return of 17%, a three-year average annualized return of 13.1%, and a 10-year average return of 9.4%. The iShares ETF has returned 17%, 9.3%, and 8.6% over the same one-, three-, and 10-year periods. The Vanguard ETF also has a minuscule expense ratio of 0.03%, compared to 0.06% for the iShares ETF.
Based on its greater diversification, its track record, and its lower expense ratio, the Vanguard Small-Cap ETF looks like the better option.
