Breadth and Dispersion Board

A board-level read of the whole S&P 500 universe in three honest measures: the percent of names trading above their 50-day average, the raw advancer and decliner counts each day, and how far the names are pulling apart (the cross-sectional dispersion of one-month returns). Counts are raw, never indexed; the 90-day data boundary and the 50-day-proxy warmup gap are marked, not hidden. A description of market structure, not a signal and not investment advice.
