questions6 answered

How much do IWM and CNDX overlap?

Which stocks do IWM and CNDX both hold?

None. IWM and CNDX have no holding in common.

Is it redundant to hold both IWM and CNDX?

No. Out of every $100 split evenly between them, none buys the same company. Half in each gives you 2,076 different holdings that behave like 121 equally weighted stocks, against 842 for IWM alone and 31 for CNDX alone. Whether that mix suits you depends on what you want to own; this is a description, not advice.

What is CNDX, next to IWM?

CNDX is iShares Nasdaq 100 UCITS ETF (ISIN IE00B53SZB19), an Irish-domiciled UCITS fund on the Nasdaq-100 index. Next to IWM, it holds no company in common, as of September 24, 2026.

Does the IWM vs CNDX overlap apply to other tickers?

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 IWM and SXRV share no company either.

How is ETF overlap calculated here?

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.
