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 | +1.15% | +0.65 | +4pp | +1.38pp | Confirming ↑ |
| 1 month | +5.65% | +2.46 | +16pp | +5.23pp | Confirming ↑ |
| 1 quarter | +5.35% | -1.73 | +27pp | +5.87pp | Weakening |
Over the last 126 sessions: price up +15.85%, breadth up (+4.85/name) · % beating 36→58 · median−ETF -2.71pp→+2.17pp.
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 2026-06-18.
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 | 5 (19%) | 10 (38%) | -5 |
| 1-Month | 3 (12%) | 3 (12%) | +0 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -0.40% | -0.05% | +0.35pp | 12 / 13 | 14 / 12 | 8 of 26 | ±2.41% |
| 5d | +1.15% | +2.11% | +0.96pp | 18 / 8 | 15 / 11 | 4 of 26 | ±4.75% |

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.
