Index volatility targeting with risk-free asset
A systematic indexes approach—Index volatility targeting with risk-free asset—defined by explicit rules, testable on history, and fragile when costs or regimes change.
Overview
A volatility targeting strategy aims to maintain a constant volatility level, which can be achieved by a periodic (weekly, monthly, etc.) rebalancing between a risky asset - in this case an index - and a riskless asset (e.g., U.S. 119 If σ is the volatility of the risky asset 120 and the volatility target is σ∗, then the allocation weight for the risky asset is given by 121 w = σ∗/σ, and the allocation weight for the risk-free asset is 1 −w.
Index volatility targeting with risk-free asset sits in the Indexes chapter of the systematic catalog. On QUSXFI we treat it as a testable hypothesis: specify entries, exits, sizing, and costs—then ask whether edge survives out-of-sample scrutiny.
Discretionary traders often arrive at similar ideas intuitively; the quantitative version forces you to write the rule before you see the next bar. That discipline is what makes results reproducible—or exposes them as luck.
