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 | +5.21% | +1.58 | -6pp | -1.22pp | Confirming ↑ |
| 1 month | +11.84% | +3.93 | +8pp | +3.28pp | Confirming ↑ |
| 1 quarter | +14.30% | +3.24 | +18pp | +1.42pp | Confirming ↑ |
Over the last 126 sessions: price up +5.36%, breadth down (-0.1/name) · % beating 42→47 · median−ETF -1.12pp→-0.10pp.
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 2026-07-02.
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 | 44 (75%) | 1 (2%) | +43 |
| 1-Month | 36 (61%) | 0 (0%) | +36 |
| 3-Month | 19 (32%) | 0 (0%) | +19 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +2.63% | +2.94% | +0.30pp | 51 / 8 | 33 / 26 | 24 of 59 | ±2.18% |
| 5d | +5.21% | +4.77% | -0.44pp | 56 / 3 | 25 / 34 | 17 of 59 | ±5.46% |
| 21d | +11.84% | +11.75% | -0.10pp | 54 / 5 | 28 / 31 | 11 of 59 | ±12.13% |
| YTD | +6.21% | +7.35% | +1.14pp | 32 / 27 | 30 / 29 | 1 of 59 | ±33.55% |
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.
