VNQ vs CNDX overlap

None by holdings, as of August 31, 2026: no company appears in both funds. They share no sector either.

None. VNQ and CNDX have no holding in common.

No. Out of every $100 split evenly between them, none buys the same company. Half in each gives you 241 different holdings that behave like 50 equally weighted stocks, against 21 for VNQ alone and 31 for CNDX alone. Whether that mix suits you depends on what you want to own; this is a description, not advice.

CNDX is iShares Nasdaq 100 UCITS ETF (ISIN IE00B53SZB19), an Irish-domiciled UCITS fund on the Nasdaq-100 index. Next to VNQ, it holds no company in common, as of August 31, 2026.

Yes. CNDX also trades as CNX1 (London, GBP), SXRV (Xetra, EUR) and CSNDX (Borsa Italiana, EUR). Each is the same portfolio in another currency, on another exchange or paying its dividends out, so VNQ and SXRV share no company either.

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.
