VUG vs CNDX overlap

60% by weight, as of August 31, 2026: heavy overlap. 57 companies appear in both funds; they make up 80% of VUG and 76% of CNDX.

The largest shared positions are NVDA, AAPL, MSFT, AMZN 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 $60 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 90 names only in VUG, 44 only in CNDX. Half in each behaves like 24 equally weighted stocks, against 17 for VUG alone and 31 for CNDX alone. Whether that duplication is a problem depends on the mix you want; this is a description, not advice.

Partly: 60% of the money in CNDX and VUG is the same, as of August 31, 2026. CNDX is iShares Nasdaq 100 UCITS ETF (ISIN IE00B53SZB19), an Irish-domiciled UCITS fund on the Nasdaq-100 index. European brokers generally don't sell US-listed ETFs such as VUG to retail clients, because those funds publish no KID (the PRIIPs key information document); UCITS funds do.

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 VUG vs SXRV also overlaps 60%.

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.
