Constituent dispersion · breadth vs the index
XLK — Technology 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 | -6.85% | -0.72 | -5pp | -2.59pp | Confirming ↓ |
| 1 month | -12.15% | -0.81 | +13pp | +4.50pp | Confirming ↓ |
| 1 quarter | -5.06% | +0.18 | +2pp | +1.07pp | Improving |
Over the last 126 sessions: price up +3.93%, breadth up (+1/name) · % beating 33→59 · median−ETF -9.37pp→+3.10pp.
Stocks above their moving average — participation breadth
Of the 72 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 2026-11-03.
New highs & new lows — by horizon
How many of the 72 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 | 7 (10%) | 16 (22%) | -9 |
| 1-Month | 3 (4%) | 8 (11%) | -5 |
| 3-Month | 3 (4%) | 4 (6%) | -1 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +1.31% | +1.48% | +0.16pp | 47 / 25 | 39 / 33 | 21 of 72 | ±3.5% |
| 5d | -6.85% | -4.29% | +2.56pp | 19 / 53 | 40 / 32 | 7 of 72 | ±10.11% |

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
XLK dispersion — data Q&A
Is XLK's move broad or carried by a few names (21 sessions)?
As of 2026-11-04: over 21 sessions the fund returned -12.15% while its median constituent returned -9.33% — a dispersion of 17.75 pp; 58% of 72 members beat the fund. Broad decline - breadth is falling with price.
How did XLK's members trade in the last session?
As of 2026-11-04: fund +1.31%, median member +1.48%, 47 advancers vs 25 decliners.
What does the dispersion page for XLK 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. 72 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.
