Definitions
In plain terms
The optimizer uses a covariance estimate and portfolio rules to seek the lowest modeled volatility, not the lowest possible realized loss.
Technical
The problem specifies covariance vintage, weight bounds, full-investment or cash rule, turnover and group constraints, solver tolerance, feasibility, and rebalance timing.
Scope
Minimum forecast volatility does not guarantee minimum future volatility or positive returns.
Examples
- A governed methodology records minimum-volatility portfolio with its source, cutoff, units, parameters, and effective version.
Common misconceptions
- Minimum-Volatility Portfolio does not have one universal implementation without the declared methodology, data basis, and constraints.
