Definitions
In plain terms
A 10% target divided by 20% measured volatility gives a raw multiplier of 0.5 before minimum and maximum limits.
Technical
The rule specifies target and measured-volatility units, estimator lag, floor for near-zero volatility, minimum and maximum exposure, rounding, and unavailable-state behavior.
Scope
It is a target exposure input, not a forecast or guaranteed risk outcome.
Formula
m = clamp(target volatility / realized volatility, m_min, m_max)m=clamp(\sigma^*/\hat\sigma,m_{min},m_{max})| Symbol | Meaning | Unit |
|---|---|---|
target volatility | declared volatility target | annualized return volatility |
realized volatility | causal volatility estimate | annualized return volatility |
m_min | minimum allowed exposure | exposure multiple |
m_max | maximum allowed exposure | exposure multiple |
Output unit: exposure multiple
Examples
- A governed methodology records exposure multiplier with its source, cutoff, units, parameters, and effective version.
Common misconceptions
- Exposure Multiplier does not have one universal implementation without the declared methodology, data basis, and constraints.
