Approximate match

IUSN gives similar asset-class exposure, but it is not a like-for-like index match.

What is IUSN?

IUSN is iShares MSCI World Small Cap UCITS ETF, a UCITS-compliant ETF that BestFolio uses when translating TNA 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.

No 3x small cap UCITS. Use 1x small cap. The source ticker has 3x exposure and the UCITS substitute has 1x exposure, so BestFolio can flag leverage differences during allocation translation.

Where TNA is used on BestFolio

TNA 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 TNA appears in an allocation, BestFolio can translate it to IUSN.
