Here's a question that sounds academic until a sector rotation rips your face off at 3x leverage. Choosing between volatility targeting and fixed leverage isn't a minor implementation detail — it's a structural decision that shapes your drawdowns, your compounding, and your psychological survival across the inevitable rough patches the ASX dishes out.

The direct answer: volatility targeting generally produces better risk-adjusted returns across regime shifts, particularly when rotating between high-beta sectors like materials and energy versus defensive plays like utilities and consumer staples. Fixed leverage is simpler, but simplicity has a hidden cost when volatility clusters — and on the ASX, it absolutely clusters.

CONCEPTVolatility targeting scales position size dynamically so your portfolio risk stays roughly constant regardless of which sector you're holding.
WARNINGFixed leverage amplifies drawdowns exactly when you can least afford it — during high-volatility sector rotations driven by macro surprises.
KEY IDEAThe real edge in volatility targeting isn't higher raw returns — it's a smoother equity curve that keeps you in the game longer.

Think of fixed leverage like driving at a constant speed regardless of road conditions. Motorway at 3am? Fine. School zone during a sector panic? Catastrophic. Volatility targeting is adaptive cruise control — it reads the road and adjusts. When materials stocks are swinging 4% daily during a China demand scare, the system dials back exposure automatically. When utilities are grinding out 0.8% daily ranges, it steps on the accelerator.

The mechanics matter here. A volatility targeting system typically measures realised volatility over a trailing window — often 20 to 60 days — then scales notional exposure so portfolio volatility hits a fixed target, say 10% annualised. AQR's research on managed futures and risk parity demonstrates that this approach reduces the variance of variance, which is the thing that actually destroys compounding. You can read more about the underpinnings via volatility targeting on Investopedia, the broader concept of risk parity on Wikipedia, and the mechanics of leverage on Investopedia. The practical takeaway for ASX sector rotation systems is to backtest both approaches across a full cycle including the 2020 crash, the 2022 rate shock, and the China-linked commodity swings — your Sharpe ratio comparison will tell the story clearly.

Stop treating leverage as a fixed dial you set once and forget. Build a simple volatility scalar, even just realised vol divided into your target, and watch your drawdown profile transform.
