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 26 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 2026-11-03.
New highs & new lows — by horizon
How many of the 26 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
XLB dispersion — data Q&A
Is XLB's move broad or carried by a few names (21 sessions)?
As of 2026-11-04: over 21 sessions the fund returned +6.24% while its median constituent returned +9.77% — a dispersion of 9.59 pp; 65% of 26 members beat the fund. Broad advance - breadth is rising with price.
How did XLB's members trade in the last session?
As of 2026-11-04: fund -2.01%, median member -1.55%, 2 advancers vs 24 decliners.
What does the dispersion page for XLB 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. 26 constituents covered, re-baked nightly from the Closelooknet lake.
