DIA Breadth & Participation
Breadth measures how many constituents actually back the fund's move. When DIA climbs but participation narrows, the rally is fragile. These oscillators are computed across the current DIA cohort — equal-weight reveals broad participation, ETF-weight reveals whether the largest constituents are doing the lifting.
Breadth is calculated over the current DIA membership snapshot. Older readings carry survivorship bias (removed names are excluded) until point-in-time holdings are stored daily.
Distance From Moving Average
Each tile is a holding (size = weight), colored by how far its close sits above/below the SMA 200. 70% of the fund is above it.
