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 | +2.76% | +1.1 | -6pp | -0.30pp | Confirming ↑ |
| 1 month | +4.41% | +0.85 | -20pp | -2.60pp | Confirming ↑ |
| 1 quarter | +8.66% | +1.05 | -15pp | -2.69pp | Confirming ↑ |
Over the last 126 sessions: price up +15.17%, breadth up (+1.53/name) · % beating 59→41 · median−ETF +1.18pp→-1.37pp.
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 2026-10-12.
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 | 39 (66%) | 3 (5%) | +36 |
| 1-Month | 13 (22%) | 3 (5%) | +10 |
| 3-Month | 7 (12%) | 2 (3%) | +5 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +0.69% | +0.87% | +0.18pp | 47 / 12 | 33 / 26 | 32 of 59 | ±1.53% |
| 5d | +2.76% | +2.13% | -0.63pp | 39 / 19 | 26 / 33 | 12 of 59 | ±2.78% |
| 21d | +4.41% | +3.03% | -1.37pp | 47 / 12 | 24 / 35 | 6 of 59 | ±8.62% |
| YTD | +11.56% | +13.25% | +1.69pp | 40 / 18 | 33 / 25 | 4 of 58 | ±26.42% |
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.

FAQ · from the current data
XLV dispersion — data Q&A
Is XLV's move broad or carried by a few names (21 sessions)?
As of 2026-10-13: over 21 sessions the fund returned +4.41% while its median constituent returned +3.03% — a dispersion of 8.62 pp; 41% of 59 members beat the fund. Broad advance - breadth is rising with price.
How did XLV's members trade in the last session?
As of 2026-10-13: fund +0.69%, median member +0.87%, 47 advancers vs 12 decliners.
What does the dispersion page for XLV measure?
It splits the fund into its members: the fund's own return against the median constituent, how many members beat the fund, advancers vs decliners, and a cumulative advance/decline line that tends to lead price. A firm fund price with a weak median and a falling A/D line is a narrow, top-heavy tape; a broad move shows the median keeping up. 59 constituents covered, re-baked nightly from the Closelooknet lake.
Is this investment advice?
No — a data surface in an investment research diary. It describes breadth inside a fund; it makes no recommendation.
