VUG vs SSAC overlap

38% by weight, as of August 31, 2026: moderate overlap. 140 companies appear in both funds; they make up 100% of VUG and 38% of SSAC.

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 $38 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 7 names only in VUG, 1,499 only in SSAC. Half in each behaves like 36 equally weighted stocks, against 17 for VUG alone and 99 for SSAC alone. Whether that duplication is a problem depends on the mix you want; this is a description, not advice.

SSAC is iShares MSCI ACWI UCITS ETF (ISIN IE00B6R52259), an Irish-domiciled UCITS fund on the MSCI All Country World (ACWI) index. Next to VUG, 38% of the money is the same, spread over 140 companies both hold, as of August 31, 2026.

Yes. SSAC also trades as ISAC (London, USD; Borsa Italiana, EUR) and IUSQ (Xetra, EUR). Each is the same portfolio in another currency, on another exchange or paying its dividends out, so VUG vs IUSQ also overlaps 38%.

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 and iShares 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.
