How to read a heatmap
Each box is one stock or fund. Bigger boxes are bigger by market value, and colour shows today’s move — the deeper the green, the bigger the gain; the deeper the red, the bigger the fall. Hover or tap a box for details, and use the top bar to switch the data set or sizing.
Heatmaps are a quick way to see whether a rally is broad (most boxes green) or driven by a few heavyweights, and which sectors are leading or lagging.
