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 | +1.02% | +0.46 | +2pp | -1.14pp | Confirming ↑ |
| 1 month | +3.44% | +1.07 | +7pp | +1.13pp | Confirming ↑ |
| 1 quarter | +14.14% | +4.46 | +22pp | +5.10pp | Confirming ↑ |
Over the last 126 sessions: price up +8.20%, breadth up (+1.98/name) · % beating 49→58 · median−ETF -0.11pp→+1.22pp.
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 2026-08-14.
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 | 13 (22%) | 16 (27%) | -3 |
| 1-Month | 9 (15%) | 0 (0%) | +9 |
| 3-Month | 6 (10%) | 0 (0%) | +6 |
| 6-Month | 3 (5%) | 0 (0%) | +3 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -0.60% | -0.43% | +0.17pp | 21 / 38 | 36 / 23 | 32 of 59 | ±1.36% |
| 5d | +1.02% | +1.31% | +0.29pp | 38 / 21 | 32 / 27 | 18 of 59 | ±2.74% |
| 21d | +3.44% | +4.67% | +1.22pp | 47 / 12 | 34 / 25 | 7 of 59 | ±8.07% |
| YTD | +8.56% | +11.56% | +2.99pp | 43 / 16 | 35 / 24 | 3 of 59 | ±26.49% |
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.
