Constituent dispersion · breadth vs the index
JXI — Global Utilities
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
JXI dispersion — data Q&A
Is JXI's move broad or carried by a few names (21 sessions)?
As of 2026-09-17: over 21 sessions the fund returned -3.21% while its median constituent returned -4.40% — a dispersion of 7.21 pp; 35% of 43 members beat the fund. Broad decline - breadth is falling with price.
How did JXI's members trade in the last session?
As of 2026-09-17: fund +1.11%, median member +0.77%, 40 advancers vs 3 decliners.
What does the dispersion page for JXI 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. 43 constituents covered, re-baked nightly from the Closelook lake.
