Performance Attribution

Weighted-return contribution ≈ prior-period portfolio weight × holding price return between consecutive snapshots. Cash contribution uses cash weight × 0 equity return (cash drag vs invested sleeve). Exact Brinson allocation/selection requires richer benchmark constituent data.
