3-Fund Portfolio

Taylor Larimore / Bogleheads forum, popularized ~2002

The most-cited DIY index portfolio. Three holdings cover the entire investable equity universe plus a broad bond stake, with no sector or factor tilts. Allocation between equity and bonds is set by individual risk tolerance; the version below is the standard age-50 "moderate" mix.

Allocation

  • 48% · US Total Market
  • 12% · International Total
  • 40% · US Aggregate Bond

Weighted expense ratio

0.032%

Weight Role Ticker Score
48% US Total Market VTI 95

40% US Aggregate Bond BND 86
  • VTI · alternates: ITOT · ITOT is a tax-loss-harvesting partner — different index family, near-identical exposure.
  • VXUS · Total ex-US developed + emerging in one fund.
  • BND · alternates: AGG · AGG works equivalently; same Bloomberg-Agg-style benchmark family.

Editorial take

The 3-fund is the default starting point for a reason: it captures essentially every diversification benefit a passive investor can reach without paying for active management, accepts no concentration risk, and rebalances cleanly across just three lots. The most common refinement is to shift the international weight toward market-cap (~40% of equity instead of the 24% below).
