Formula

w₁* = (σ₂² − ρσ₁σ₂) / (σ₁² + σ₂² − 2ρσ₁σ₂)

The minimum-variance weights solve for the lowest-risk combination regardless of returns — useful when you trust your risk estimates more than your return forecasts (which is always). The result often holds more of the low-vol asset than intuition suggests; with low correlation, total risk can dip below either component.
