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 2026-08-06.

% 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 | 44 (35%) | 15 (12%) | +29 |
| 1-Month | 16 (13%) | 2 (2%) | +14 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -0.96% | +0.60% | +1.56pp | 77 / 45 | 92 / 32 | 31 of 124 | ±3.8% |
| 5d | +9.77% | +5.83% | -3.94pp | 103 / 21 | 38 / 86 | 7 of 124 | ±9.58% |
| 21d | -3.41% | -6.79% | -3.38pp | 40 / 84 | 46 / 78 | 7 of 124 | ±12.65% |
| YTD | +103.10% | +66.09% | -37.01pp | 117 / 2 | 37 / 82 | 0 of 119 | ±86.66% |
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
