Market breadth
How many stocks are actually going up? Advancers vs decliners each session, the share of stocks above their own moving averages, fresh 52-week highs and lows, and how breadth stacks up across every trailing window — for all 508 US stocks we track. Go deeper with the stock-by-stock breadth heatmap and the daily return distributions.
Advancers vs decliners#
Every session's bar sums to the whole universe — green advancers from the bottom, red decliners on top — so the red/green split of the market is read directly.
Stocks above their moving averages#
Share of stocks trading above their own 20-, 50- and 200-day moving averages. Short windows swing with every pullback; the 200-day line is the slow-moving health check — readings under ~20% have marked washouts, over ~80% broad strength.
New 52-week highs and lows#
Stocks closing at a fresh 52-week high (up) vs a fresh 52-week low (down). Persistent new-low expansion is the classic stress signal; simultaneous highs and lows mark a split market.
Cumulative advance–decline line vs SPY#
The running sum of each day's net advancers, next to SPY over the same window. When SPY climbs but the A/D line stalls, fewer stocks are carrying the advance.
Breadth by trailing window#
Share of stocks with a positive return over each window, as of now (1D uses live prices during market hours). A weak 1M row under a strong 1Y row = recent deterioration.

| Other | 100% | 100% | 0% | 0% | 0% | — | 1 |
Cell = % of the group's stocks with a positive return over the window (green > 50% positive, red < 50%).
Methodology#
Universe: all actively tracked US stocks (currently 508; dual share classes deduplicated) — today's membership walked back through history, so early years cover fewer names and carry survivorship bias. Daily advances/declines use dividend-adjusted closes (an ex-dividend gap is not a decline). Moving averages and 52-week extremes use split-adjusted closes, and each stock only counts toward a measure once it has enough trading history (200 sessions for the 200-day MA, 252 for highs/lows). Historical rows are end-of-day; during market hours the advancer/decliner charts append a provisional "today so far" bar from live intraday prices (refreshed every ~10 minutes), and the trailing-window panel's 1D column reflects the same live prices. Not investment advice.
FAQ
- What is market breadth?
- Market breadth measures how many stocks participate in a move, rather than how far a cap-weighted index travels. An index can rise on a handful of megacaps while most stocks fall — breadth metrics like advancers vs decliners, % of stocks above their moving averages, and new highs vs lows make that visible.
- What is a breadth divergence?
- When the index makes new highs but the cumulative advance–decline line (or % of stocks above their 200-day average) does not, the advance is narrowing — fewer stocks are carrying it. Divergences don't time tops, but historically broad advances have been more durable than narrow ones.
