Constituent dispersion · breadth vs the index
XLB — Materials Select Sector
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 | +1.44% | +0.08 | -4pp | -1.65pp | Confirming ↑ |

| 1 quarter | -1.86% | -1.62 | +8pp | +2.57pp | Confirming ↓ |
Over the last 126 sessions: price up +6.84%, breadth up (+0.5/name) · % beating 48→54 · median−ETF -0.85pp→+1.20pp.
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 2026-07-24.
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 | 13 (50%) | 3 (12%) | +10 |
| 1-Month | 5 (19%) | 1 (4%) | +4 |
| 3-Month | 5 (19%) | 1 (4%) | +4 |
| 6-Month | 2 (8%) | 1 (4%) | +1 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +1.93% | +1.93% | +0.00pp | 20 / 6 | 13 / 13 | 11 of 26 | ±3.65% |
| 5d | +1.44% | +1.07% | -0.38pp | 16 / 10 | 12 / 14 | 7 of 26 | ±4.31% |
| 21d | +0.20% | +1.40% | +1.20pp | 15 / 11 | 14 / 12 | 3 of 26 | ±8.48% |

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.
