Risk DNA
30% of VST's variance is systematic (explainable by market, sector, and subsector factors); the rest is stock-specific.
VST carries 69% stock-specific risk against a peer average of 69% — more of what happens here is specific to this name than is typical for its cohort.
Subsector (-0.6%) covaried negatively with VST 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.
