IVV vs IWDA overlap

71% by weight, as of October 14, 2026: heavy overlap. 442 companies appear in both funds; they make up 99% of IVV and 71% of IWDA.

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 $71 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 62 names only in IVV, 806 only in IWDA. Half in each behaves like 59 equally weighted stocks, against 44 for IVV alone and 83 for IWDA alone. Whether that duplication is a problem depends on the mix you want; this is a description, not advice.

Partly: 71% of the money in IWDA and IVV is the same, as of October 14, 2026. IWDA is iShares Core MSCI World UCITS ETF (ISIN IE00B4L5Y983), an Irish-domiciled UCITS fund on the MSCI World index. European brokers generally don't sell US-listed ETFs such as IVV to retail clients, because those funds publish no KID (the PRIIPs key information document); UCITS funds do.

Yes. IWDA also trades as SWDA (London, GBP; Borsa Italiana, EUR) and EUNL (Xetra, EUR). Each is the same portfolio in another currency, on another exchange or paying its dividends out, so IVV vs EUNL also overlaps 71%.

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.
