Breadth vs the sector.

Most screens show the sector's price. These show what its members are doing underneath — is the move broad, or carried by a few mega-caps? Median constituent vs the index, advancers vs decliners, how many names beat the index, and a cumulative advance/decline line that tends to turn before price. 40 ETFs & index cuts · closes through 2026-07-24.

What changed below the surface · 21-day

Where the constituents' advance/decline is pulling away from the ETF's price — the early read, before the headline reflects it.

Weakening — breadth falling under firm price
