VOOG vs VUAA overlap

67% by weight, as of September 30, 2026: heavy overlap. 151 companies appear in both funds; they make up 100% of VOOG and 69% 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 $67 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 1 names only in VOOG, 352 only in VUAA. Half in each behaves like 28 equally weighted stocks, against 19 for VOOG 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: 67% of the money in VUAA and VOOG is the same, as of September 30, 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 VOOG 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 VOOG vs VUAG also overlaps 67%.

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.
