Market Breadth is one of the more traditional ways of measuring broad market participation to help gauge the health of the equity markets. Over the years it has lost some of its following to new and more shiny (complicated) market indicators, but it has never lost its usefulness. In developing the relative strength process, I added breadth measures as a relative strength pillar by comparing the breadth across the sectors and subsectors to measure relative participation levels. This chart and snapshot set is a compilation of the most common breadth indicators I have used and shared over more than a decade to give you a one stop rundown of participation.
