Constituent dispersion · breadth vs the index
XSD — SPDR S&P Semiconductor (EW)
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.

Over the last 126 sessions: price up +103.03%, breadth up (+11.26/name) · % beating 51→37 · median−ETF +0.06pp→-4.74pp.
Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +7.26% | +6.95% | -0.31pp | 43 / 0 | 20 / 23 | 10 of 43 | ±3.36% |

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.
