Hats off to a couple of readers, who noted my earlier heat map post and commented on the value of the heat maps and market data found on the FinViz site. Above we see a snapshot of just two sectors from a much larger map. Note how the stocks that are most highly weighted in the sectors have the largest boxes. The boxes are shaded red if the stock is down; green if up; and grey if neutral. The map allows a quick look at the colors of each sector, but also is organized by subsectors. This enables you to see if strength or weakness within the sectors is more general or mixed.
I will have more to say about FinViz in an upcoming post. The value here is in condensing a large amount of information into a clear display that facilitates quick processing and action.
