QTUM — Defiance Quantum
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.

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
QTUM dispersion — data Q&A
Is QTUM's move broad or carried by a few names (21 sessions)?
As of 2026-10-15: over 21 sessions the fund returned -0.63% while its median constituent returned +1.15% — a dispersion of 9.16 pp; 58% of 62 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 QTUM's members trade in the last session?
As of 2026-10-15: fund +0.08%, median member +0.38%, 36 advancers vs 26 decliners.
What does the dispersion page for QTUM 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. 62 constituents covered, re-baked nightly from the Closelooknet lake.
Is this investment advice?
No — a data surface in an investment research diary. It describes breadth inside a fund; it makes no recommendation.
