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.

200-day 84.43% 103/122 above
% 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 | 73 (59%) | 3 (2%) | +70 |
| 1-Month | 8 (6%) | 3 (2%) | +5 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +2.27% | +1.73% | -0.54pp | 92 / 31 | 54 / 70 | 30 of 124 | ±3.87% |
| 5d | +0.09% | -0.52% | -0.61pp | 59 / 64 | 59 / 65 | 22 of 124 | ±6.89% |
| 21d | -11.88% | -12.72% | -0.85pp | 23 / 101 | 57 / 67 | 9 of 124 | ±12.19% |
| YTD | +96.06% | +60.07% | -35.99pp | 114 / 5 | 35 / 84 | 0 of 119 | ±81.59% |
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.
What drove the move — contribution = weight × return
