Approximate match

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

Include an issuer page or KID so the identity can be rechecked.

What is IUSN?

IUSN is iShares MSCI World Small Cap UCITS ETF, the European-listed product BestFolio uses when translating TNA. Most targets are UCITS ETFs; some commodity and leveraged targets are UCITS-eligible ETCs or ETPs instead. Product structure and retail eligibility must be checked for the exact ISIN.

No 3x small cap UCITS. Use 1x small cap. The source ticker has 3x exposure and the mapped target 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.
