VTI vs VUAA overlap

Nearly: 88% of the money in VTI and VUAA sits in the same companies at the same weights, as of August 31, 2026. The other 12% is weight differences, plus 3,003 names only in VTI and 3 only in VUAA.

88% by weight, as of August 31, 2026: nearly the same fund. 500 companies appear in both funds; they make up 89% of VTI and 100% of VUAA.

The largest shared positions are NVDA, AAPL, MSFT, AMZN and GOOGL. Ranked by the smaller of the two weights, which is the part you would own twice.

Out of every $100 split evenly between them, about $88 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 3,003 names only in VTI, 3 only in VUAA. Half in each behaves like 50 equally weighted stocks, against 59 for VTI alone and 43 for VUAA alone. Whether that duplication is a problem depends on the mix you want; this is a description, not advice.

Partly: 88% of the money in VUAA and VTI is the same, as of August 31, 2026. VUAA is Vanguard S&P 500 UCITS ETF (USD) Accumulating (ISIN IE00BFMXXD54), an Irish-domiciled UCITS fund on the S&P 500 index. European brokers generally don't sell US-listed ETFs such as VTI to retail clients, because those funds publish no KID (the PRIIPs key information document); UCITS funds do.

Yes. VUAA also trades as VUAG (London, GBP), and VUSA (ISIN IE00B3XXRP09) is its distributing share class. Each is the same portfolio in another currency, on another exchange or paying its dividends out, so VTI vs VUAG also overlaps 88%.

For every company held by both funds we take the smaller of its two weights and add them up. The weights come from the full holdings files Vanguard publish, not a top-10 sample, and companies are matched by their ISIN so share classes stay apart. Sector overlap applies the same rule to the issuers' sector labels; "behaves like N equally weighted stocks" is one over the sum of the squared weights.
