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.

Stocks above their moving average — participation breadth
Of the 124 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 2026-07-28.

% 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 | 4 (3%) | 114 (92%) | -110 |
| 1-Month | 1 (1%) | 99 (80%) | -98 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -6.65% | -6.73% | -0.09pp | 6 / 117 | 62 / 62 | 26 of 124 | ±4.36% |

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
