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.

Stocks above their moving average — participation breadth
Of the 21 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 2026-08-28.
New highs & new lows — by horizon
How many of the 21 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.

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +0.63% | +0.17% | -0.45pp | 14 / 7 | 7 / 14 | 12 of 21 | ±1.28% |

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
XLE dispersion — data Q&A
Is XLE's move broad or carried by a few names (21 sessions)?
As of 2026-08-28: over 21 sessions the fund returned +6.31% while its median constituent returned +6.21% — a dispersion of 6.96 pp; 48% of 21 members beat the fund. Broad advance - breadth is rising with price.
How did XLE's members trade in the last session?
As of 2026-08-28: fund +0.63%, median member +0.17%, 14 advancers vs 7 decliners.
What does the dispersion page for XLE 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. 21 constituents covered, re-baked nightly from the Closelook lake.
