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 | +4.37% | +1.53 | +6pp | +0.88pp | Confirming ↑ |
| 1 month | +4.32% | +1.36 | -3pp | -0.56pp | Confirming ↑ |
| 1 quarter | +14.26% | +2.41 | -1pp | +0.05pp | Confirming ↑ |
Over the last 126 sessions: price up +6.10%, breadth up (+0.81/name) · % beating 49→53 · median−ETF -0.02pp→+0.14pp.
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 2026-07-28.
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 | 51 (86%) | 0 (0%) | +51 |
| 1-Month | 32 (54%) | 0 (0%) | +32 |
| 3-Month | 26 (44%) | 0 (0%) | +26 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +2.36% | +2.66% | +0.30pp | 58 / 1 | 34 / 25 | 27 of 59 | ±2.36% |
| 5d | +4.37% | +3.85% | -0.52pp | 49 / 10 | 29 / 30 | 6 of 59 | ±5.16% |
| 21d | +4.32% | +4.45% | +0.14pp | 47 / 12 | 31 / 28 | 9 of 59 | ±7.32% |
| YTD | +8.49% | +9.72% | +1.23pp | 38 / 21 | 32 / 27 | 4 of 59 | ±27.76% |
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.
