CSPX is the closest listed UCITS substitute BestFolio uses for IWB.

What is CSPX?

CSPX is iShares Core S&P 500 UCITS ETF, a UCITS-compliant ETF that BestFolio uses when translating IWB into a European-broker-friendly allocation. UCITS funds are designed for EU and UK retail access and carry the required investor documents that US-listed ETFs usually lack.

Russell 1000 approx. S&P 500 (0.99 correlation). The source ticker has 1x exposure and the UCITS substitute has 1x exposure, so BestFolio can flag leverage differences during allocation translation.

Where IWB is used on BestFolio

IWB is in the UCITS translation table, but no currently published strategy universe lists it directly.

This page still exists because the UCITS table also supports imported portfolios, fallback ticker coverage, and future strategy additions. If IWB appears in an allocation, BestFolio can translate it to CSPX.
