VGT vs VUAA overlap

40% by weight, as of August 31, 2026: moderate overlap. 74 companies appear in both funds; they make up 88% of VGT and 40% of VUAA.

The largest shared positions are NVDA, AAPL, MSFT, AVGO and MU. 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 $40 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 244 names only in VGT, 429 only in VUAA. Half in each behaves like 23 equally weighted stocks, against 13 for VGT alone and 43 for VUAA alone. Whether that duplication is a problem depends on the mix you want; this is a description, not advice.

VUAA is Vanguard S&P 500 UCITS ETF (USD) Accumulating (ISIN IE00BFMXXD54), an Irish-domiciled UCITS fund on the S&P 500 index. Next to VGT, 40% of the money is the same, spread over 74 companies both hold, as of August 31, 2026.

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 VGT vs VUAG also overlaps 40%.

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.
