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 23 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 23 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

|---|---|---|---|---|---|---|---|

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 2026-08-28: over 21 sessions the fund returned +6.01% while its median constituent returned +8.65% — a dispersion of 13.32 pp; 61% of 23 members beat the fund. Broad advance - breadth is rising with price.
How did XLC's members trade in the last session?
As of 2026-08-28: fund +1.42%, median member +1.20%, 18 advancers vs 4 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.
Is this investment advice?
