How To Read It

  • If equal weight rises with the index, participation is broadening across the average stock.
  • If cap weight keeps winning while equal weight stalls, leadership is getting narrower and concentration is doing more of the work.
  • This chart is most useful near highs, when headline strength can hide weak internals.
