None. VWO and CSPX have no holding in common.

No. Out of every $100 split evenly between them, none buys the same company. Half in each gives you 5,500 different holdings that behave like 80 equally weighted stocks, against 37 for VWO alone and 44 for CSPX alone. Whether that mix suits you depends on what you want to own; this is a description, not advice.

CSPX is iShares Core S&P 500 UCITS ETF (ISIN IE00B5BMR087), an Irish-domiciled UCITS fund on the S&P 500 index. Next to VWO, it holds no company in common, as of August 31, 2026.

Yes. CSPX also trades as CSP1 (London, GBP), SXR8 (Xetra, EUR) and CSSPX (Borsa Italiana, EUR). Each is the same portfolio in another currency, on another exchange or paying its dividends out, so VWO and SXR8 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.
