The better choice depends on whether you want broad small-company exposure, an index with eligibility screens, a value tilt, active security selection, or a heavily traded vehicle. Six funds have documented characteristics that can be compared: VB, SCHA, AVUV, VIOO, VBR and IWM.
Use the comparison below as a decision guide—not a universal ranking. Expense ratios are dated fund figures and can change, so confirm them with the issuer before investing.

What makes these small-cap ETFs different?
“Small-cap” does not describe one identical investment universe. Each fund may use a different index, eligibility screen, rebalance process or active-management mandate. Those choices affect diversification, sector exposure, factor tilts, turnover and the way the fund may behave relative to other small-cap ETFs.
- Broad index exposure: VB follows the CRSP US Small Cap Index, while SCHA follows the Dow Jones U.S. Small-Cap Total Stock Market Index.
- Eligibility-screened exposure: VIOO follows the S&P SmallCap 600, whose index methodology determines which companies qualify.
- Value-oriented exposure: VBR follows the Morningstar US Small Cap Value Index.
- Active factor strategy: AVUV is actively managed and emphasizes companies the manager considers to have lower valuations and higher profitability.
- Trading-oriented benchmark exposure: IWM follows the Russell 2000 and is widely used by traders, but trading popularity does not make it automatically preferable as a long-term holding.
Six small-cap ETFs to compare in 2025
| ETF | Method | Universe or tilt | Expense ratio and date | Potential use |
|---|---|---|---|---|
| VB | Passive index | CRSP US Small Cap Index; broad U.S. small-company exposure | Not stated in the cited materials | Core small-cap allocation for investors seeking a broad benchmark |
| SCHA | Passive index | Dow Jones U.S. Small-Cap Total Stock Market Index | 0.030% effective June 11, 2026 | Low-cost broad small-cap exposure, subject to confirming the current fee |
| AVUV | Active management | Companies with lower valuations and higher profitability, as assessed by Avantis | 0.25% as of January 1, 2026 | Investors deliberately seeking an active small-cap value/profitability tilt |
| VIOO | Passive index | S&P SmallCap 600 | 0.07% as of December 19, 2025 | Exposure to the S&P small-cap index rather than the broader CRSP or Dow Jones universe |
| VBR | Passive index | Morningstar US Small Cap Value Index | 0.05% as of April 28, 2026 | Rules-based small-cap value exposure |
| IWM | Passive index | Russell 2000 | 0.19%; figure reported by Kiplinger and should be verified with iShares | Highly traded Russell 2000 exposure and a vehicle often used by traders |

How to choose among them
Choose broad exposure when you want a building block
VB and SCHA are the closest matches for an investor who wants a diversified small-cap allocation without explicitly selecting value or profitability factors. They still track different benchmarks, so their holdings and returns will not be identical.
Choose an index screen when eligibility rules matter
VIOO’s S&P SmallCap 600 exposure reflects that index’s inclusion requirements. It is not interchangeable with a total small-cap-market fund simply because both use the small-cap label.
Choose a value tilt only when you accept different behavior
VBR and AVUV are designed for investors who intentionally want value-related exposure. VBR applies a rules-based index approach. AVUV is active and adds the manager’s assessment of valuation and profitability. A factor tilt can lag a broad small-cap benchmark for long periods.
Separate long-term allocation from trading needs
IWM’s trading activity can be useful for investors who need a liquid Russell 2000 vehicle. For a long-term holding, compare its cost, benchmark and tax or portfolio role with lower-cost alternatives rather than treating liquidity or popularity as a quality ranking.

An expense ratio is an annual fund operating expense deducted from assets; it is not a one-time purchase charge. The figures above come with different effective dates, including dates in 2026, and should be rechecked before an order. A lower fee helps only if the fund’s index, factor exposure and portfolio role fit your plan.
A practical selection checklist
- Define the role: total small-cap allocation, small-cap value, active factor exposure or a trading instrument.
- Read the benchmark name and methodology rather than relying on the fund’s “small-cap” label.
- Compare the current issuer-reported expense ratio and its effective date.
- Review diversification, concentration and turnover in the latest fact sheet or prospectus.
- Decide whether you can tolerate periods when small caps or value stocks trail large-cap or growth benchmarks.
- Check bid-ask spreads, trading volume and order type if you expect to trade frequently.
- Rebalance according to your investment plan instead of switching funds solely because one had a better recent return.
Important limitations of a “best ETF” list
The six funds above do not establish a verified seven-fund ranking, and the available evidence does not provide a consistent, dated comparison of holdings breadth, concentration and liquidity for every candidate. Returns also cannot be ranked fairly without a common measurement date and total-return methodology. Treat any list that presents one fund as universally best with caution.

Risks to understand before buying
- Small-company stocks can be more volatile and less financially resilient than large-company stocks.
- Value and profitability tilts can underperform broad small-cap indexes for extended periods.
- Index methodologies can produce materially different sector and company exposures.
- Active management introduces manager decisions, higher costs and the possibility of underperformance.
- ETF liquidity can vary by market conditions; a fund’s trading volume does not remove market risk.
