Volatility & Variance: Reading the Risk Fingerprint
VUKE.LSE (Vanguard FTSE 100 UCITS ETF) carries an annualised volatility of 11.9%, categorised as moderate relative to the long-run US equity benchmark of approximately 15%. VERX.LSE (Vanguard FTSE Developed Europe ex UK UCITS) registers at 12.9%, a moderate reading by the same standard.
VUKE.LSE and VERX.LSE carry virtually identical annualised volatility — both within a fraction of a percentage point of each other — making the risk profile of either fund essentially interchangeable on this dimension.
On the downside, VUKE.LSE's maximum peak-to-trough drawdown of 24.0% represents a severe bear-market drawdown over the study period. VERX.LSE's worst drawdown of 17.8% was a notable pullback. VERX.LSE demonstrated stronger capital preservation characteristics, absorbing market shocks with less peak-to-trough damage.
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.
