Divergence over time — price vs breadth, by horizon
The hero read is the 1-month picture; here the same price↔breadth divergence across 1 week / 1 month / 1 quarter, computed over the 126-session history. A/D /name is net advancers-minus-decliners per covered constituent; % beating Δ and median−ETF Δ show how participation shifted. Price rising while those fall = the move is narrowing under the surface.
| Horizon | Price | A/D /name | % beating Δ | Median−ETF Δ | Read |
|---|---|---|---|---|---|
| 1 week | -0.61% | -0.54 | +4pp | +1.41pp | Weakening |
| 1 month | +3.24% | +0.85 | -7pp | +0.23pp | Confirming ↑ |
| 1 quarter | +1.68% | +1.46 | +23pp | +5.12pp | Confirming ↑ |
Over the last 126 sessions: price down -0.27%, breadth down (-2.88/name) · % beating 64→58 · median−ETF +1.12pp→+2.88pp.
Stocks above their moving average — participation breadth
Of the 26 covered constituents, the share trading above each simple moving average — the classic breadth gauge. A firm index price with a low %-above-MA is a narrow, top-heavy tape. As of 2026-08-14.
New highs & new lows — by horizon
How many of the 26 covered constituents closed today at a new high (or low) over each window, and the net. A shrinking net as the index holds up = fewer names leading.
| Horizon | New highs | New lows | Net |
|---|---|---|---|
| 5-Day | 3 (12%) | 11 (42%) | -8 |
| 1-Month | 1 (4%) | 2 (8%) | -1 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +0.44% | -0.12% | -0.56pp | 12 / 14 | 11 / 15 | 10 of 26 | ±1.51% |
| 5d | -0.61% | -0.83% | -0.23pp | 9 / 17 | 12 / 14 | 7 of 26 | ±3.41% |
| 21d | +3.24% | +6.12% | +2.88pp | 17 / 9 | 15 / 11 | 2 of 26 | ±9% |

Median − ETF below zero means the typical name is lagging the cap-weighted index — the move is top-heavy. "Beat" counts constituents outperforming the ETF over the window. Dispersion is the cross-sectional standard deviation of constituent returns — high = a stock-picker's tape, low = pure beta.
