Volatility & Variance: Reading the Risk Fingerprint
EUNL.XETRA (iShares Core MSCI World UCITS ETF USD (Acc) EUR) carries an annualised volatility of 13.2%, categorised as moderate relative to the long-run US equity benchmark of approximately 15%. IS3N.XETRA (iShares Core MSCI Emerging Markets IMI UCITS) registers at 14.3%, a moderate reading by the same standard.
IS3N.XETRA is marginally more volatile than EUNL.XETRA by 1.1% annualised. For most US long-term investors this difference is unlikely to be psychologically meaningful, though it will compound over multi-decade holding periods.
On the downside, EUNL.XETRA's maximum peak-to-trough drawdown of 18.8% represents a notable pullback over the study period. IS3N.XETRA's worst drawdown of 23.0% was a severe bear-market drawdown. EUNL.XETRA demonstrated stronger capital preservation during the period's worst stress events, which is particularly relevant for US investors approaching retirement or drawing down a portfolio.
When evaluating these two funds for a US-domiciled portfolio, it is important to consider that volatility and drawdown metrics are calculated on trailing historical data. Past standard deviations do not guarantee future behaviour, particularly around US Federal Reserve policy shifts, which have historically been the primary driver of cross-asset correlation breakdowns.
