Breadth heatmap
Every one of our 508 tracked stocks as a row, every trading day as a column, colored by return. Bad market days are vertical red stripes; sector trouble shows as red blocks; a stock in trouble is a horizontal band. Group rows by sector or size, switch rows to market-cap-proportional, or color by trailing 1M/3M returns to see regimes instead of noise. Part of the market breadth overview.
Methodology#
Universe: all actively tracked US stocks, dual share classes deduplicated, ordered by market cap within each group. Daily returns use dividend-adjusted closes; trailing modes compound those dailies over 5/21/63 sessions. Colors clip at ±4% (daily), ±8% (1W), ±15% (1M) and ±30% (3M) so typical moves stay distinguishable. Data is end-of-day. Click any cell to open that stock's quote page. Not investment advice.
FAQ
- How do I read this chart?
- Each row is one stock, each column one trading session, and the cell color is that stock's return — green up, red down, brighter = bigger move. A vertical red stripe means nearly everything fell that day (a market-wide event); a red rectangle confined to one sector band means the trouble was sector-specific; a persistent horizontal red band is a single stock in a downtrend.
- What do the trailing 1W / 1M / 3M modes show?
- Instead of a single day's move, each cell shows the compounded return over the trailing 5, 21 or 63 sessions ending that day. Trailing windows smooth daily noise and reveal regime stretches — a market where most rows glow red in trailing-1M mode has broad, persistent weakness even if individual days look mixed.
