Risk decomposition

HD

Market → sector → subsector → α-residual · 2026-04-22 → 2026-10-12

HD factor & risk decomposition snapshot
Market
+7.7%
Sector
-16.6%
Subsector
-0.8%
α residual
-3.2%
Stock
-13.0%

Every position carries the market, its sector, and its subsector before any stock-specific move. The waterfall splits HD's realized return into those benchmark layers; the α residual is what the three hedge layers do not explain.
