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 | -4.31% | -0.32 | -3pp | +2.47pp | Confirming ↓ |
| 1 month | -13.98% | -0.64 | +18pp | +8.25pp | Confirming ↓ |
| 1 quarter | -10.56% | -0.67 | -2pp | +2.49pp | Confirming ↓ |
Over the last 126 sessions: price down -4.38%, breadth up (+0.88/name) · % beating 42→56 · median−ETF -3.72pp→+5.57pp.
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 2026-11-10.
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 | 12 (17%) | 10 (14%) | +2 |
| 1-Month | 2 (3%) | 6 (8%) | -4 |
| 3-Month | 2 (3%) | 4 (6%) | -2 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -1.15% | -0.25% | +0.90pp | 29 / 43 | 50 / 22 | 28 of 72 | ±2.4% |
| 5d | -4.31% | -3.40% | +0.90pp | 21 / 51 | 45 / 27 | 13 of 72 | ±10.4% |
| 21d | -13.98% | -8.44% | +5.54pp | 24 / 48 | 40 / 32 | 4 of 72 | ±19.32% |
| YTD | +17.61% | +22.72% | +5.11pp | 47 / 25 | 38 / 34 | 0 of 72 | ±61.09% |
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 2026-11-10: over 21 sessions the fund returned -13.98% while its median constituent returned -8.44% — a dispersion of 19.32 pp; 56% 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 2026-11-10: fund -1.15%, median member -0.25%, 29 advancers vs 43 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.
