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 | -2.27% | -0.47 | -8pp | -0.84pp | Confirming ↓ |
| 1 month | +4.75% | +0.9 | -4pp | -1.16pp | Confirming ↑ |
| 1 quarter | +6.94% | +0.76 | -12pp | -2.17pp | Confirming ↑ |
Over the last 126 sessions: price up +32.89%, breadth up (+5.28/name) · % beating 46→38 · median−ETF -4.22pp→-2.24pp.
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 2026-10-12.
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 | 14 (19%) | 32 (44%) | -18 |
| 1-Month | 4 (6%) | 6 (8%) | -2 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -1.22% | -1.27% | -0.05pp | 20 / 51 | 35 / 37 | 24 of 72 | ±3.04% |
| 5d | -2.27% | -0.55% | +1.73pp | 33 / 39 | 44 / 28 | 5 of 72 | ±6.33% |
| 21d | +4.75% | +2.09% | -2.66pp | 42 / 30 | 27 / 45 | 5 of 72 | ±12.74% |

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 2026-10-13: over 21 sessions the fund returned +4.75% while its median constituent returned +2.09% — a dispersion of 12.74 pp; 38% of 72 members beat the fund. Broad advance - breadth is rising with price.
How did XLK's members trade in the last session?
As of 2026-10-13: fund -1.22%, median member -1.27%, 20 advancers vs 51 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.
