Comprehensive Analysis of Efficient Advisors, LLC SEC 13F Filing
1. Portfolio Overview

Efficient Advisors, LLC has reported a substantial expansion in assets under management (AUM), with the total portfolio value surging by 378.3% from $358.15 million to $1.71 billion quarter-over-quarter. This dramatic increase indicates a significant inflow of capital, likely driven by new client acquisitions or institutional mandates rather than mere market appreciation. The portfolio compos...

2. Key Holdings

The portfolio is dominated by a collection of "mega-cap" Vanguard and Dimensional ETFs, suggesting a strategy focused on capturing market beta and specific factor premiums at the lowest possible cost.

  • Core Equity Exposure: The top three positions are all broad U.S. equity funds: VTI (Vanguard Total Stock Market ETF) at 7.35%, VBR (Vanguard Small-Cap Value ETF) at 7.02%, and VOO (Vanguard S&P 500 ETF) at 6.56%. This triad forms the core of the U.S. equity allocation, offering a blend of total market, large-cap growth, and small-cap value exposure.
  • Fixed Income Dominance: Fixed income plays a massive role in this portfolio, with BND (Total Bond Market) and BIV (Intermediate-Term Bond) taking the 4th and 7th spots, respectively. Combined with shorter duration bonds like BSV (9th), the allocation to fixed income is substantial, likely serving to dampen portfolio volatility.
  • Factor and International Tilts: The holdings list reveals a distinct tilt toward specific investment factors, particularly "Value" and "Small-Cap." Dimensional ETFs (e.g., DFAC, DUHP) appear frequently throughout the top 20, indicating the firm employs a sophisticated factor-based indexing approach rather than simple market-cap weighting.
3. Sector Allocation

The sector allocation data confirms that Efficient Advisors operates almost exclusively through fund wrappers, with 99.54% of the portfolio classified as ETFs.

  • Asset Class Diversification: While traditional sector breakdowns (Technology, Healthcare, etc.) are not provided, the underlying ETF tickers reveal a multi-asset class construction. The portfolio spans U.S. Equities (VTI, VOO), International Developed Markets (VEA, VGK), Emerging Markets (VWO), and a broad spectrum of Fixed Income (Aggregate Bonds, TIPS, Corporate Bonds).
  • Real Estate: A notable specific allocation is to VNQ (Vanguard Real Estate ETF) at 3.13%, providing exposure to Real Estate Investment Trusts (REITs) as a distinct asset class.
  • Individual Securities: There is negligible exposure to individual stocks, with only JPMorgan Chase & Co. ($713K) appearing as a direct holding, representing a mere 0.04% of the portfolio. This reinforces the view that the firm relies on fund managers for security selection.
