Bear Market Breadth: How Many Stocks Are Really in a Bear Market?
The share of each index's members trading more than 20% below their own 252-session high — S&P 500, Nasdaq-100, Dow 30 and a Russell-2000-style cohort, daily since 2011 from our own price history. The index can sit at record highs while half its stocks are in private bear markets; this is the gauge that shows it — with the contrarian base rates behind every reading.
Today's reading
As of the July 6, 2026 close, the share of index members trading more than 20% below their own 252-session highs — S&P 500: 34.1% (84th percentile) · Nasdaq-100: 48.5% (92th percentile) · Dow Jones 30: 16.7% (74th percentile) · Russell 2000-style: 43.3% (59th percentile). Historically these readings were contrarian: the highest quartile of each index's history preceded above-baseline forward returns.
Historically contrarian: days in this index's highest bear-share quartile preceded +6.5% avg SPY returns over the next quarter vs +3.1% baseline. Context, not a forecast.
Share of members in a bear market — S&P 500
What followed each reading — S&P 500
Forward SPY returns from every day since 2011, bucketed by this index's own bear-share quartiles. The pattern is the familiar contrarian U: the highest readings — the scariest charts — preceded above-baseline returns. Deterioration is a caution flag for what you own, not a sell-the-index signal.
| Bear-share bucket | Next 21 sessions | Next 63 sessions | N |
|---|---|---|---|
| Lowest quartile (few stocks in bear) | +0.86% · 69%↑ | +2.12% · 79%↑ | 981 |
| Second quartile | +0.53% · 65%↑ | +1.66% · 68%↑ | 968 |
| Third quartile | +0.67% · 66%↑ | +2.20% · 69%↑ | 974 |
| Highest quartile (most stocks in bear) | +2.15% · 69%↑ | +6.52% · 84%↑ | 975 |
| All days (baseline) | +1.05% · 67%↑ | +3.08% · 75%↑ | 3,898 |
Forward returns on SPY closes; overlapping windows. Current members applied across history — the standard construction for this chart, which slightly flatters past readings (survivorship). Base rates, not signals.
How Bear Market Breadth Works
- 1Each stock vs its own highFor every member of the index, we track its closing price against its own trailing 252-session high. More than 20% below that high is the standard definition of an individual bear market; more than 10% below is a correction. The index can sit near record highs while many of its members are 20, 30, 40% off theirs.
- 2Count the share, dailyThe headline series is the percentage of members in a bear market each day, computed across the actual membership: S&P 500 and Dow 30 from State Street's daily ETF holdings, Nasdaq-100 from Nasdaq's own list, and a Russell-2000-style cohort (stocks ranked 1,001-3,000 by market cap in our universe — iShares walls its holdings file, so we build the honest approximation and label it).
- 3The survivorship caveat, stated plainlyToday's members are applied across history — the standard construction for this chart (including the viral versions), but it means past readings slightly understate historical stress: the weakest stocks of past years were later removed from the indexes. Treat deep history as directionally right, not precise.
- 4Attach the base ratesFor each index we bucket every day since 2011 by the bear share's own quartiles and show what the index ETF did over the following month and quarter. The pattern is contrarian: the highest readings preceded above-baseline returns — washed-out breadth marked exhaustion more often than acceleration.
