Headline indices can hide what the broader market is actually doing. Market breadth measures participation — how many stocks are advancing versus declining, how many are making new highs versus new lows, and how widely a move is shared across sectors — so you can spot regime shifts before they show up in the index.
Trendvue tracks the core breadth indicators for the market, updated after every close. Use them to confirm a trend, catch divergences where the index rises while participation narrows, and read whether buying or selling is broad-based or concentrated in a handful of names.
