IWF vs SSAC overlap

39% by weight, as of October 14, 2026: moderate overlap. 215 companies appear in both funds; they make up 98% of IWF and 44% of SSAC.

The largest shared positions are NVDA, AAPL, MSFT, GOOGL and META. 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 $39 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 156 names only in IWF, 1,424 only in SSAC. Half in each behaves like 41 equally weighted stocks, against 20 for IWF 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 IWF, 39% of the money is the same, spread over 215 companies both hold, as of October 14, 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 IWF vs IUSQ also overlaps 39%.

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 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.
