Constituent dispersion · breadth vs the index
XLV — Health Care 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 | +0.92% | -0.73 | -13pp | -1.91pp | Weakening |
| 1 month | +6.01% | +1.14 | -15pp | -2.45pp | Confirming ↑ |
| 1 quarter | +10.28% | +0.29 | -15pp | -2.20pp | Confirming ↑ |
Over the last 126 sessions: price up +5.05%, breadth up (+0.15/name) · % beating 54→41 · median−ETF +0.42pp→-1.23pp.
Stocks above their moving average — participation breadth
Of the 59 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 59 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 | 20 (34%) | 11 (19%) | +9 |
| 1-Month | 6 (10%) | 6 (10%) | +0 |
| 3-Month | 5 (8%) | 0 (0%) | +5 |
| 6-Month | 3 (5%) | 0 (0%) | +3 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +0.70% | +0.86% | +0.16pp | 38 / 21 | 33 / 26 | 31 of 59 | ±1.91% |
| 5d | +0.92% | -0.29% | -1.21pp | 27 / 32 | 19 / 40 | 15 of 59 | ±3.59% |
| 21d | +6.01% | +4.78% | -1.23pp | 46 / 13 | 24 / 35 | 7 of 59 | ±6.72% |
| YTD | +5.45% | +5.29% | -0.16pp | 35 / 24 | 29 / 30 | 3 of 59 | ±27.83% |
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.
