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 | +4.49% | +0.39 | -5pp | -2.65pp | Confirming ↑ |
| 1 month | +10.51% | +0.49 | +6pp | -1.01pp | Confirming ↑ |
| 1 quarter | +38.11% | +5.86 | -17pp | -7.37pp | Confirming ↑ |
Over the last 126 sessions: price up +33.60%, breadth up (+6.58/name) · % beating 48→39 · median−ETF -0.15pp→-6.75pp.
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 2026-06-18.
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 | 20 (28%) | 20 (28%) | +0 |
| 1-Month | 11 (15%) | 15 (21%) | -4 |
| 3-Month | 10 (14%) | 7 (10%) | +3 |
| 6-Month | 9 (13%) | 7 (10%) | +2 |
| 52-Week | 8 (11%) | 7 (10%) | +1 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +3.04% | +0.87% | -2.17pp | 47 / 25 | 23 / 49 | 7 of 72 | ±4.79% |
| 5d | +4.49% | -0.31% | -4.80pp | 34 / 38 | 25 / 47 | 5 of 72 | ±9.27% |
| 21d | +10.51% | +3.87% | -6.64pp | 44 / 27 | 28 / 43 | 4 of 71 | ±22.54% |

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.
