Volatility & Variance: Reading the Risk Fingerprint
SKYY.US (First Trust Cloud Computing ETF) carries an annualised volatility of 25.3%, categorised as high relative to the long-run US equity benchmark of approximately 15%. CLOU.US (Global X Cloud Computing) registers at 25.5%, a high reading by the same standard.
SKYY.US and CLOU.US 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, SKYY.US's maximum peak-to-trough drawdown of 48.9% represents a catastrophic peak-to-trough collapse over the study period. CLOU.US's worst drawdown of 47.8% was a catastrophic peak-to-trough collapse. CLOU.US 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.
