IEFA vs CNDX overlap

0.3% by weight, as of October 14, 2026: little overlap. 3 companies appear in both funds; they make up 0.3% of IEFA and 0.5% of CNDX.

The largest shared positions are NBIS, FER and CCEP. 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 $0 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 2,616 names only in IEFA, 98 only in CNDX. Half in each behaves like 112 equally weighted stocks, against 261 for IEFA alone and 31 for CNDX alone. Whether that duplication is a problem depends on the mix you want; 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 IEFA, 0.3% of the money is the same, spread over 3 companies both hold, as of October 14, 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 IEFA vs SXRV also overlaps 0.3%.

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.
