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 | -1.77% | -0.56 | +0pp | -0.12pp | Confirming ↓ |
| 1 month | +4.06% | +1.44 | +8pp | +0.59pp | Confirming ↑ |
| 1 quarter | +9.95% | +1.37 | +5pp | +1.69pp | Confirming ↑ |
Over the last 126 sessions: price up +4.16%, breadth down (-0.22/name) · % beating 49→47 · median−ETF -0.11pp→-0.22pp.
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 2026-07-10.
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 | 11 (19%) | 15 (25%) | -4 |
| 1-Month | 4 (7%) | 0 (0%) | +4 |
| 3-Month | 2 (3%) | 0 (0%) | +2 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -0.82% | -0.06% | +0.76pp | 27 / 30 | 47 / 12 | 28 of 59 | ±1.84% |
| 5d | -1.77% | -1.01% | +0.76pp | 16 / 43 | 38 / 21 | 23 of 59 | ±3.01% |
| 21d | +4.06% | +3.84% | -0.22pp | 47 / 12 | 28 / 31 | 6 of 59 | ±8.56% |
| YTD | +4.33% | +7.07% | +2.74pp | 33 / 26 | 31 / 28 | 0 of 59 | ±30.14% |
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.
