"Breadth indicators" refer to measurements or statistics used to gauge the overall health or strength of a market or a particular sector. These indicators provide a broad overview by analyzing the number of companies or stocks that are advancing or declining, the volume of stocks being traded, or the overall level of market participation. They help investors or analysts assess the breadth or extent of market movements, indicating whether the market trends are broad and widespread or if they are concentrated in just a few stocks.
