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 2026-07-28.
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.

| 1-Month | 5 (22%) | 1 (4%) | +4 |

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.
