The read · October 19, 2026
Breadth is weak: across 14 indicators, all US stocks sit at the 23rd percentile of the past five years on average, little changed from the 21st a week ago.
- Nasdaq-100 members hold up better (40th) than all Nasdaq-listed stocks (21st).
- Weakest: NYSE McClellan Summation Index (4th), Bullish Percent Index (8th), new highs minus new lows, 10-day (10th). Strongest: Nasdaq advancing issues through the session (54th), equal weight vs cap weight, 3 months (39th).

Every indicator on its own range
Each track runs from the indicator’s weakest to its strongest reading in the range (the last five years), with the median at the centre line; the solid marker is October 19, 2026, the dashed one five sessions earlier. Right is always broader. “Since” marks indicators with less history than the range. Context indicators do not measure this universe’s own stocks and are left out of the average; A-D marks indicators built from the same advancing and declining counts.
The Cumulative reading over time
The same average, with each day ranked only against the five years before it, so a past reading shows what was knowable then. Each line is a 10-session average; the answer card shows the latest day. All US stocks are drawn against VTI, the total US market fund; the S&P 500 against SPY; the two Nasdaq universes against QQQ.
All US stocks: 23rd (10-session average)
S&P 500 members*: 27th (10-session average)
Nasdaq-100 members*: 39th (10-session average)
All Nasdaq-listed: 21st (10-session average)
What followed
For all US stocks, the weakest fifth was followed by a median +6.4% over the next quarter against +4.2% for every day: weak breadth during selloffs has tended to come before rebounds. The weaker setup was weak breadth near a record: below 30 with VTI within 2% of its high, the next year returned −6.1% against +12.5% for every near-record day, on 39 completed days that cluster into a few episodes. For all Nasdaq-listed stocks, the weakest fifth was followed by a median +6.4% over the next quarter against +5.5% for every day: weak breadth during selloffs has tended to come before rebounds. The weaker setup was weak breadth near a record: below 30 with QQQ within 2% of its high, the next year returned −10.7% against +21.2% for every near-record day, on 52 completed days that cluster into a few episodes.

Limits
The Cumulative reading is an average, so one extreme indicator can move it; the tracks show which ones do, and indicators built from the same advancing and declining counts are marked A-D because they are related readings. Several indicators start in 2016, when our corrected advance-decline record begins, so their 10-year and full ranges are shorter and say so. The S&P 500 and Nasdaq-100 use today’s members carried back and are never graded. The graded universes are not fully survivorship-free either: their advancing and declining counts keep delisted stocks, but moving-average breadth, the Bullish Percent Index and new highs and lows are built from stocks with a live price file, so read the “what followed” tables as indicative.

How Market Breadth Works
- 1Every indicator on its own rangeEach indicator is ranked against its own history over the last five years, the last ten years or its whole record, and drawn as a track from its weakest to its strongest reading with today marked on it. Right always means broader participation.
- 2Four universesAll US stocks, S&P 500 members, Nasdaq-100 members and every Nasdaq-listed stock, each with its own advancing and declining counts, moving-average shares, new highs and lows and point-and-figure signals.
- 3A Cumulative readingThe average percentile of the indicators that measure the universe’s own stocks. Futures candle direction, and exchange-wide TICK for the S&P 500 and Nasdaq-100, are shown as context and left out of the average.
- 4Replayed and testedThe history ranks each past day only against the five years before it, and for all US stocks and all Nasdaq-listed stocks the page shows what VTI and QQQ did next by Cumulative zone.
