Overview of AVUV vs VTSAX: Why Small Cap Value Could Outperform

This episode of the BiggerPocketsMoney podcast (hosts Mindy Jensen and Scott Trench) features Frank Vasquez (Risk Parity Radio). It explains what "small‑cap value" means, why investors in the FIRE community recommend it alongside broad index funds like VTSAX, and how different small‑cap value ETFs (notably AVUV) differ because of the underlying index rules and filters they use. The discussion focuses on diversification benefits, index construction differences (Russell, S&P SmallCap 600, CRSP), and practical ways to evaluate which small‑cap value vehicle might fit in your portfolio.

Key takeaways

  • Small‑cap value is a well‑studied factor (size + value) shown historically to offer different return/volatility behavior than large‑cap growth, producing diversification benefits when paired with broad market funds like VTSAX.
  • “Index fund” is a broad term—many ETFs are algorithmic rules‑based products (not human stock‑picking active funds). AVUV is algorithmic/passive in that sense, not hand‑picked active management.
  • Different small‑cap value ETFs use different indexes/filters. Those choices (size cutoffs, profitability/quality filters, weighting rules) materially affect returns and risk over time.
  • AVUV has outperformed many plain small‑cap value benchmarks historically because it applies additional profitability/quality filters that remove lower‑quality companies; its expense ratio is roughly 0.20–0.25%.
  • During some periods (e.g., last several months/this year at time of recording) small‑cap value has materially outperformed the S&P 500, but periods of long large‑cap growth dominance have also occurred—no one can reliably time which will lead next.

What is "small‑cap value" (plain language)

  • Two factor axes commonly used to segment equities: size (small → large) and style (value ←→ growth). Combined into a 3×3 “style box.”
  • Small‑cap value = smaller market cap companies that score as value (lower price relative to fundamentals like earnings).
  • These companies tend to be in traditional, cyclical, or “old economy” sectors (financials, industrials, consumer staples, utilities, small manufacturers, etc.).
  • Historically small‑cap value often behaved differently than large‑cap growth and sometimes outperformed over long horizons. That differential is what investors seek for diversification and potential long‑term premium.

How small‑cap value ETFs differ (what makes AVUV different)

  • Indexes and filters matter. Common small‑cap value index families:
    • Russell (e.g., Russell 2000 Value): basic size + value segmentation; historically often the weakest performer among the three listed.
    • S&P SmallCap 600 (SmallCap 600 Value): includes a profitability filter—excludes some unprofitable firms—so tends to perform better than the basic Russell construct.
    • CRSP (used by Vanguard): has a different size boundary (bleeds into mid‑cap) and typically also includes profitability filters; yields a different risk/return profile.
  • Avantis/DFA approaches (e.g., AVUV) layer additional profitability/quality filters on top of a small‑cap value index—effectively eliminating lower‑quality companies in the cohort. That filter is the main reason AVUV has shown stronger historical returns vs. simpler small‑cap value indexes.
  • AVUV is not “active” in the human stock‑picker sense; it’s a rules‑based/indexed ETF using a proprietary algorithmic construction.

Practical implications and portfolio guidance

  • Diversification rationale: combine a large‑cap core (VTSAX or S&P 500) with a small‑cap value sleeve to capture different performance cycles—when one lags, the other can lead.
  • For accumulation phase investors: keep it simple—low‑cost broad index funds and steady contributions are key. Tweaks matter more when you approach decumulation/withdrawals.
  • For building a more nuanced allocation: consider mixing large‑cap blend/growth (VTSAX/VOO) with a small‑cap value ETF (choose index/filter based on your preference for quality/profitability screening).
  • International small‑cap value and non‑equity sleeves (gold, bonds) are additional ways to diversify, but they add complexity and unpredictable relative performance.
  • Beware concentration risk in market‑cap weighted funds: cap‑weighted indexes (VTSAX, VOO) naturally concentrate in the largest winners (top handful of names can be a very large share), which increases exposure to sector/tech cycles (e.g., AI investment cycles).

How to evaluate a small‑cap value fund (step‑by‑step)

  • Use Morningstar fund pages to examine:
    • Fund portfolio holdings and sector breakdown
    • Top holdings concentration
    • Size and value exposure (style box)
  • Use Portfolio Visualizer to analyze factor exposures (size, value, momentum, quality), historical returns vs. peers, and correlations.
  • Compare the index rules: does the ETF use Russell, S&P SmallCap 600, CRSP, or a proprietary index? Does it apply a profitability/quality screen?
  • Check expense ratio and tax characteristics (if investing in taxable accounts).
  • Read the prospectus/strategy text for how the index/filtering works (note: some proprietary indexes won’t publish full rules publicly).
  • Consider long run windows (10–30+ years where available) rather than just recent months; small‑cap value performance cycles are lengthy and variable.

Notable quotes from the episode

  • “All index funds are algorithmic funds.” — Frank Vasquez (emphasizing index construction is rules‑based).
  • “It’s the difference between somebody pushing a broom and a Roomba.” — Frank (a metaphor for human active management vs. algorithmic rules).
  • “If you have two things that perform differently at different times, that is the fundamental principle of diversification.” — Frank

Actionable next steps (if you want to apply this)

  1. Decide whether you want a small‑cap value sleeve in your portfolio (especially if you’re moving toward retirement/withdrawals).
  2. Use Morningstar and Portfolio Visualizer to compare the small‑cap value ETFs you’re considering (Russell vs. S&P 600 vs. CRSP vs. Avantis/DFA filters).
  3. Check expense ratios and whether the ETF’s rules (profitability/quality filters) align with your comfort level.
  4. If you’re in accumulation mode: don’t over‑optimize—low‑cost, simple allocations and continued contributions usually beat trying to time factor tilts.
  5. If you’re moving to decumulation or want more robustness vs. tech/large‑cap concentration risk, consider a modest allocation to small‑cap value (and international/value variants) and re‑evaluate periodically.
