Market breadth: S&P 500
How many S&P 500 stocks are taking part in the move: the share of index members trading above their 50-day and 200-day moving averages.
% of S&P 500 stocks above their 50-day average
Short-term participation. As a rule of thumb, readings above about 80% are often seen as stretched and below about 20% as washed out.
% of S&P 500 stocks above their 200-day average
Long-term trend health. Above 50% means most of the index is in a long-term uptrend.

How to read market breadth
An index can rise because a handful of very large companies are rising, even while most of its members fall. Breadth shows whether a move is broad or narrow.
- Index rising and breadth rising: most stocks are joining in, so the move is broad.
- Index rising but breadth falling: fewer stocks are carrying the index. Traders often treat this divergence as a warning sign.
- 50-day vs 200-day: the 50-day line reacts quickly to short swings; the 200-day line moves slowly and describes the longer trend.
Breadth is a context tool, not a timing signal on its own. Readings can stay stretched or washed out for a long time.
