If Vanguard is the responsible, steady parent of the index fund world — reliable, a little boring, beloved by everyone — then Avantis is the academically brilliant younger sibling who showed up and said, "What if we did all that, but smarter?"
Both companies make exceptional products. Both are firmly in the "low cost, evidence-based investing" camp. But they're doing different things, targeting different investor needs, and understanding the distinction matters if you want to build a portfolio beyond a single VTI position.
This is our deep dive into the ETFs we actually recommend — and why.
Vanguard: The Original Indexing Revolution
Let's give credit where it's due. Jack Bogle founded Vanguard in 1975, launched the first retail index fund, and changed investing forever. The company's mutual ownership structure — where the funds own the company, not outside shareholders — means Vanguard has a structural incentive to keep costs as low as possible. There's no outside profit motive to maximize.
The result: expense ratios that are almost insultingly cheap.
| ETF | Expense Ratio | Holdings | Strategy |
|---|---|---|---|
| VTI | 0.03% | ~3,600+ US stocks | Cap-weighted total market |
| VOO | 0.03% | 500 largest US companies | Cap-weighted large cap blend |
| VBR | 0.07% | ~850 small cap value stocks | CRSP US Small Cap Value Index |
For investors who want the simplest possible exposure to the US market, VTI and VOO are hard to beat. They're not trying to be clever. They're trying to be the market, as cheaply as possible. For the overwhelming majority of investors, that is exactly what they should be.
The Vanguard limitation isn't cost or philosophy — it's factor exposure. VTI and VOO are cap-weighted, which means mega-cap growth companies (Apple, Microsoft, Amazon, Nvidia) constitute a huge share of the fund. You own the market, but you're heavily tilted toward the largest, often most expensive companies by valuation. You're not capturing the small cap value premium, or any other factor premium that historical research has identified.
That's where Avantis enters the conversation.
Avantis: Factor Investing for the Rest of Us
Avantis Investors was founded in 2019 by Eduardo Repetto and a team of former Dimensional Fund Advisors (DFA) researchers. DFA has been the gold standard of academic factor investing for decades, but it was traditionally only accessible through fee-based financial advisors. Avantis democratized the approach: the same research-driven, factor-tilted methodology, available as retail ETFs anyone can buy on any brokerage.
The Avantis philosophy sits in an interesting middle ground. It's not passive indexing in the Vanguard sense — it's not just tracking a pre-defined index blindly. But it's not active management in the traditional sense either. It uses systematic, rules-based methods grounded in academic research to emphasize stocks with characteristics that have historically been associated with higher returns: smaller size, lower valuations (value), and higher profitability.
Here's the Avantis ETF lineup relevant to the VTI & Chill system:
| ETF | Expense Ratio | Focus | 5-Year Return |
|---|---|---|---|
| AVUS | 0.15% | Broad US equity with factor tilts | 15.16% |
| AVLV | 0.15% | US large cap value + profitability | 15.71% (3-yr) |
| AVUV | 0.25% | US small cap value + profitability | 19.27% |
| AVSC | 0.25% | Broad US small cap with factor tilts | — |
| AVDV | 0.36% | Intl developed small cap value | 15.89% |
| AVDS | 0.30% | Broader intl developed small cap | — |
| AVES | 0.36% | Emerging markets value | — |
| AVEE | 0.42% | Emerging markets small cap | — |
The AVUV Difference: Profitability Screening
AVUV doesn't just buy the cheapest small cap stocks — it buys cheap, profitable small cap stocks. This profitability screen is what separates it from Vanguard's VBR. A passive small-cap value index holds every cheap small-cap stock including unprofitable ones heading toward zero. AVUV's methodology, combining value and profitability screens, avoids the "value trap" problem — cheap stocks that are cheap because they're failing businesses. The Fama-French five-factor model identifies this combination as particularly potent, and it's where AVUV's return edge comes from.
The Real Comparison: Philosophy Differences
The core difference between Vanguard and Avantis isn't cost — both are extremely cheap by any reasonable standard. The difference is philosophy.
Vanguard says: "You can't consistently outperform the market. Stop trying. Be the market."
Avantis says: "You can't consistently outperform the market through stock-picking or timing. But there are systematic, well-documented factors that have historically generated premiums. We can tilt toward those factors systematically, at low cost, based on decades of peer-reviewed research."
Both positions are defensible. Neither is wrong. Vanguard's approach is simpler and completely appropriate for most investors. Avantis's approach captures factor premiums but requires trusting the academic research and holding through periods when factors don't deliver.
In practical terms: AVUS versus VTI is a coin-toss for most investors. The factor tilt in AVUS versus VTI is subtle. The expense ratio difference (0.15% vs. 0.03%) is minimal. Either is an excellent core holding.
AVUV versus Vanguard's small cap offerings is where the real differentiation appears. Vanguard's VBR (Small Cap Value ETF) is good, but it uses a less refined methodology. It captures the value factor but doesn't emphasize profitability the way AVUV does. The Avantis approach, by combining value and profitability screens, avoids the "value trap" problem — cheap stocks that are cheap for a very good reason (they're failing businesses).
The honest caveat on factor investing
Factor premiums are real but lumpy. Value underperformed growth dramatically from 2010 to 2020. Any investor who added Avantis factor tilts in 2010 watched their "enhancement" lag VTI for a decade before the cycle turned. Avantis ETFs are not a short-term upgrade over VTI — they're a long-term structural tilt that requires patience measured in years, not quarters. If you can't handle watching your portfolio diverge from a plain S&P 500 return for extended periods, stick with VTI. If you believe in the research, the Avantis suite is the best retail tool for capturing it.
Which Should You Use?
The VTI & Chill framework maps to this choice clearly:
- Good tier (VTI only): Pure Vanguard. Simplest, cheapest, excellent. No factor tilts, no complexity.
- Better tier (VTI + AVUV ± AVLV): Vanguard for the broad market core, Avantis for the factor tilts. The two companies working together.
- Best tier (Merriman-inspired global suite): Avantis throughout — AVUS or VTI as core, AVUV, AVLV, AVDV, AVDS, AVES, AVEE for complete factor and geographic diversification.
You don't have to choose between them. Most portfolios in the Better and Best tiers use both. The practical implementation for a two-fund factor portfolio: 80% VTI + 20% AVUV captures the broad market while adding a meaningful small cap value tilt at minimal complexity.
The Bottom Line
Vanguard built the index fund revolution. VTI and VOO are exceptional products that form the backbone of the Good and Better portfolio tiers. No investor should feel like they're settling by building their portfolio around VTI — the 0.03% expense ratio, 3,600+ holdings, and cap-weighted self-cleansing structure make it genuinely hard to beat in simplicity and cost.
Avantis built on Vanguard's foundation by adding factor tilts backed by decades of academic research. AVUV's 19.27% five-year return, $20B+ in assets, and profitability screening make it the cleanest retail vehicle for capturing the small cap value premium. AVDV does the same for international developed markets, AVES for emerging markets.
Use Vanguard for your simple, broad market core. Consider Avantis when you're ready to add factors. You don't have to choose — most serious portfolios use both, and that's exactly what the Better and Best tiers are designed around.
