How to Read the Heat Map

Use the heat map to spot breadth and concentration quickly, then click into the symbols or sectors that stand out instead of treating color intensity as a finished thesis.

Heat-map tiles are prompts to investigate. They compress a lot of information and can hide liquidity or catalyst details that matter more.
