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.

% of constituents above their 50-day average — breadth over the last year; 50% is the participation midpoint
New highs & new lows — by horizon
How many of the 124 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 | 48 (39%) | 9 (7%) | +39 |
| 1-Month | 19 (15%) | 2 (2%) | +17 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +1.09% | +0.13% | -0.96pp | 63 / 60 | 44 / 80 | 36 of 124 | ±2.84% |
| 5d | +5.46% | +3.32% | -2.13pp | 100 / 24 | 49 / 75 | 16 of 124 | ±7.09% |

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.
