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
ARKK dispersion — data Q&A
Is ARKK's move broad or carried by a few names (21 sessions)?
As of 2026-09-04: over 21 sessions the fund returned +13.85% while its median constituent returned +8.44% — a dispersion of 17.62 pp; 31% of 42 members beat the fund. Weakening below the surface - the A/D line is falling while price holds up; leadership is narrowing.
How did ARKK's members trade in the last session?
As of 2026-09-04: fund -1.06%, median member -0.59%, 16 advancers vs 26 decliners.
What does the dispersion page for ARKK 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. 42 constituents covered, re-baked nightly from the Closelook lake.
