Why this form. A squarified treemap is the one layout that shows the whole index at once with importance built into the geometry — you cannot look at it without seeing that a large company had a loud week. It is also the form every trader already knows, so the learning cost is zero. What it is not is a price screen.

What is missing, and why. This map was designed with three colourings. The other two — how a company performed against the guidance it gave, and how broadcast calls on it turned out — need a judgement we cannot yet make honestly: matching free-text guidance onto reported numbers, and outcomes for televised calls that nothing has tracked since April. We would rather ship the one we can stand behind than colour a map from a source that cannot fill it. What management actually said is quoted, verbatim and unscored, on each stock page.
