Out of every $100 split evenly between them, about $0 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 100 names only in QQQ, 384 only in SMEA.

Whether that duplication is a problem depends on the mix you want; this is a description, not advice.

SMEA is iShares Core MSCI Europe UCITS ETF EUR (Acc) (ISIN IE00B4K48X80), an Irish-domiciled UCITS fund on the MSCI Europe index. Next to QQQ, 0.2% of the money is the same, spread over 1 companies both hold, as of October 16, 2026.

Yes. SMEA also trades as IMAE (Euronext Amsterdam, EUR) and EUNK (Xetra, EUR). Each is the same portfolio in another currency, on another exchange or paying its dividends out, so QQQ vs EUNK also overlaps 0.2%.

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 Invesco 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.
