The Verdict
This is a cross-asset comparison rather than a like-for-like one. BNDX is a fixed-income fund and VXUS is an equity fund, so they are not competing for the same slot — most portfolios hold some of each. The useful question is not which is better but what mix of the two suits your time horizon and tolerance for drawdowns.
ETFValuer's model scores VXUS at 76.5 (Grade B+) and BNDX at 57.7 (Grade C), but read that gap carefully: the score blends return, risk-adjusted performance, cost and drawdown across a single ranking of all funds, so an asset class with structurally lower expected returns will always score below one with higher returns and higher risk. It is a useful comparison between Global Multi-Region funds and between International Bonds funds — not a verdict that one of these two belongs in your portfolio and the other doesn't. Most investors hold both, in a ratio set by how long they have to recover from a bad year.

Bold marks the better value in each row. "Better" is directional only (e.g. lower cost, higher return) — it isn't a recommendation by itself. See the full methodology.
Cost
On cost, the two are essentially tied — BNDX charges 0.07% a year versus VXUS's 0.05%. A difference this small (about $2.00 a year on a $10,000 position) isn't a reason to choose one fund over the other.
What BNDX's Fees Cost You
BNDX charges an expense ratio of 0.07% a year, deducted automatically from the fund's value. Small percentages compound into real money — adjust the figures below to see the impact on your own numbers.
Assumes a constant gross return and no additional contributions — a simplification, but it isolates exactly what the expense ratio costs. Try the full fee calculator to model contributions and compare any two funds.
Performance & Risk
Over the trailing 3 years, VXUS returned +56.94% versus +12.13% for BNDX — a gap of about 44.8 percentage points. On risk, BNDX has held up better historically, with a shallower max drawdown (-2.93% vs. -13.58%). VXUS currently has the better risk-adjusted return (Sharpe ratio of 0.95 vs. -0.99), meaning it delivered more return per unit of volatility taken on. Comparing these returns directly is misleading, though — a bond fund losing less in a selloff and an equity fund gaining more in a rally are both doing exactly what they were built to do. Judge each against its own role.
How Closely Do They Track Each Other?
Over the last 3.0 years of daily returns (752 shared trading days), BNDX and VXUS show a low correlation of 0.308 — largely independent of each other. These funds move largely on their own schedules. Combining them is a real diversification decision rather than a redundant one, which is the case where owning both can genuinely reduce portfolio volatility.
| Measure | Value | What it means |
|---|---|---|
| Daily return correlation | 0.308 | Low — largely independent of each other |
| R-squared | 9.5% | 9.5% of BNDX's daily moves are explained by VXUS's |
| Tracking error (annualised) | 14.60% | Typical yearly spread between the two funds' returns |
| Annualised return over 3.0y | BNDX +3.86% · VXUS +16.64% | VXUS ahead by 12.77 points a year |
Correlation alone understates how far these can drift. Across every rolling 12-month window in the period, BNDX finished as much as +8.9 points ahead of VXUS at the best extreme and -48.5 points at the worst — a 57.4-point spread between the best and worst year of relative performance. Two funds can correlate tightly day to day and still deliver very different outcomes over any single year you happen to hold them.
Calculated from daily total returns over the trailing 3-year window, recomputed every day this site refreshes. Correlation of 1.00 means the two funds moved in lockstep; 0.00 means their daily moves were unrelated.
Holdings Overlap
BNDX and VXUS hold 1 of the same companies among their top 10 positions. Those shared names make up 1.2% of BNDX and 2.5% of VXUS. That's modest duplication — the funds are mostly distinct at the top, so holding both can still add diversification.
| Shared Holding | BNDX Weight | VXUS Weight |
|---|---|---|
| Vanguard Cmt Funds-Vanguard Market Liquidity Fund | 1.25% | 2.48% |
Compares the top 10 reported holdings from each fund's most recent SEC N-PORT-P filing, so it understates total overlap — funds tracking similar indexes overlap far more deeply than the top 10 alone can show. Search any company across all tracked funds with the Stock Overlap tool.
Which One Should You Pick?
Lean BNDX if…
- Current income matters to you — it yields 4.46% against 2.56%
- It has been the calmer ride (3.5% volatility vs 16.7%) with a shallower worst-case fall (-2.9% vs -13.6%)
Lean VXUS if…
- You want the lower running cost — 0.05% vs 0.07%, about $2 a year less on a $10,000 position
- You care about return per unit of risk — its Sharpe ratio of 0.95 beats -0.99
- You weight recent results heavily — it returned 56.9% over 3 years against 12.1%
- You want the deeper, more liquid market ($650B in assets vs $123B) and the tighter spread (0.204% vs 0.649%)
These two are not really substitutes, so "both, in some proportion" is often the right answer rather than picking one. Model the blend with the Portfolio Blender.
