EEM and CSPX: what people ask

questions6 answered

How much do EEM and CSPX overlap?

None by holdings, as of September 24, 2026: no company appears in both funds. By sector, 83% of their money sits in the same sectors, led by Information Technology.

Which stocks do EEM and CSPX both hold?

None. EEM and CSPX have no holding in common.

Is it redundant to hold both EEM and CSPX?

No. Out of every $100 split evenly between them, none buys the same company. Half in each gives you 1,673 different holdings that behave like 68 equally weighted stocks, against 28 for EEM alone and 44 for CSPX alone. Whether that mix suits you depends on what you want to own; this is a description, not advice.

What is CSPX, next to EEM?

CSPX is iShares Core S&P 500 UCITS ETF (ISIN IE00B5BMR087), an Irish-domiciled UCITS fund on the S&P 500 index. Next to EEM, it holds no company in common, as of September 24, 2026.

Does the EEM vs CSPX overlap apply to other tickers?

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 EEM and SXR8 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.
