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 | -0.71% | +0.53 | +24pp | +4.01pp | Improving |
| 1 month | -0.92% | +0.08 | +21pp | +2.82pp | Improving |
| 1 quarter | +12.79% | +2.8 | +27pp | +3.61pp | Confirming ↑ |
Over the last 126 sessions: price up +5.57%, breadth up (+1.07/name) · % beating 54→68 · median−ETF +1.01pp→+2.72pp.
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 2026-08-03.
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 | 16 (27%) | 16 (27%) | +0 |
| 1-Month | 10 (17%) | 2 (3%) | +8 |
| 3-Month | 8 (14%) | 0 (0%) | +8 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -0.19% | +1.00% | +1.19pp | 40 / 19 | 41 / 18 | 20 of 59 | ±2.1% |
| 5d | -0.71% | +2.09% | +2.80pp | 43 / 16 | 47 / 12 | 10 of 59 | ±5.17% |
| 21d | -0.92% | +1.80% | +2.72pp | 37 / 22 | 40 / 19 | 9 of 59 | ±8.56% |
| YTD | +5.24% | +7.46% | +2.22pp | 39 / 20 | 30 / 29 | 1 of 59 | ±26.84% |
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.
