iShares MSCI World Small Cap UCITS ETF

IUSN is almost always paired with broad developed-market core equity ETFs, most commonly SXR8 (S&P 500) at 25-70%, IWDA or VWCE at 20-60%, and emerging market funds like EMIM or IS3N at 10-30%. Precious metals, especially gold via IGLD or GOLD, appear in roughly half the portfolios at 5-25%, while bonds are rare and only appear at 1-5% in a few cases. The typical IUSN allocation is 5-15%, with the highest at 20% in the Golden Butterfly portfolio, and it consistently serves as a diversifier that adds small-cap exposure without dramatically increasing volatility, as seen in portfolios with Sharpe ratios above 1.1 where IUSN sits alongside large-cap and emerging market holdings.

The community uses IUSN as a satellite holding to enhance long-term growth while keeping drawdowns moderate. In the top-performing portfolios, IUSN is blended with gold and EM to create a barbell effect, such as the Basic portfolio with 60% SXR8, 20% IGLD, 10% EMIM, and 10% IUSN, which achieves a 1.29 Sharpe with only 16.8% max drawdown. The Perfecta III portfolio takes a more aggressive stance with 45% XDWD, 30% IS3N, and 15% IUSN, plus 5% gold and 5% Bitcoin, showing that members use IUSN to capture small-cap risk premia while relying on gold or bonds to cushion equity downturns. Notably, IUSN appears in both conservative and aggressive strategies, but never as the largest holding, indicating it is viewed as a complement to core large-cap exposure rather than a standalone driver of returns.
