Market breadth measures how many stocks are actually participating in a move — not just where the headline index closed. If an index rises while only a few names advance, breadth is narrow and the move rests on few shoulders.
One straightforward measure is the share of stocks showing positive momentum over a period. Wide participation and narrow participation can look identical at index level, which is exactly what a breadth reading separates.

Breadth is context, not a forecast. A high reading says participation is wide; a low one says a move depends on fewer names. It does not predict direction, and nothing here is investment advice.
