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 down -10.07%, breadth down (-3.42/name) · % beating 55→42 · median−ETF +0.16pp→-0.12pp.
Stocks above their moving average — participation breadth
Of the 31 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 2026-10-14.
New highs & new lows — by horizon
How many of the 31 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.

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
XLU dispersion — data Q&A
Is XLU's move broad or carried by a few names (21 sessions)?
As of 2026-10-14: over 21 sessions the fund returned +1.71% while its median constituent returned +1.59% — a dispersion of 3.06 pp; 42% of 31 members beat the fund. Broad advance - breadth is rising with price.
How did XLU's members trade in the last session?
As of 2026-10-14: fund -0.36%, median member +0.38%, 21 advancers vs 10 decliners.
What does the dispersion page for XLU 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. 31 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.
