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.

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

XLC dispersion — data Q&A

Is XLC's move broad or carried by a few names (21 sessions)?

As of 2026-09-04: over 21 sessions the fund returned +0.76% while its median constituent returned +0.86% — a dispersion of 9.29 pp; 52% of 23 members beat the fund. Improving below the surface - the A/D line is rising while price is flat-to-down; more names participating than the headline shows.

How did XLC's members trade in the last session?

As of 2026-09-04: fund -1.19%, median member -1.80%, 3 advancers vs 19 decliners.

What does the dispersion page for XLC 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. 23 constituents covered, re-baked nightly from the Closelook lake.
