Risk DNA
34% of XYZ's variance is systematic (explainable by market, sector, and subsector factors); the rest is stock-specific.
XYZ carries 66% stock-specific risk against a peer average of 71% — less of what happens here is specific to this name than is typical for its cohort.
Sector (-0.4%) covaried negatively with XYZ over this window, offsetting its variance rather than adding to it. Clamped to 0% for the bar and the remaining layers renormalized, so the percentages above sum to 100.
