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 2026-10-15.
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
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +1.46% | +1.95% | +0.49pp | 16 / 5 | 14 / 9 | 6 of 23 | ±2.45% |
| 5d | +0.33% | +0.30% | -0.03pp | 17 / 6 | 10 / 13 | 9 of 23 | ±3.9% |

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 2026-10-15: over 21 sessions the fund returned -0.17% while its median constituent returned -3.30% — a dispersion of 8.50 pp; 39% of 23 members beat the fund. Weakening below the surface - the A/D line is falling while price holds up; leadership is narrowing.
How did XLC's members trade in the last session?
As of 2026-10-15: fund +1.46%, median member +1.95%, 16 advancers vs 5 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 Closelooknet lake.
