What supports the view

No major confirming factor has secured control.

What restrains conviction

Index trend architecture has not delivered a durable upward expansion.
Breadth remains too narrow or inconsistent for a high-conviction position.
Constituent persistence remains divided or predominantly negative.
The group is not yet delivering dependable relative outperformance.
Positive contribution is concentrated in a small leadership cohort.

Independent sentiment overlay Sentiment held separate

Qualified news coverage is too thin to alter the technical positioning view.

Evidence that would change the view

A completed weekly reclaim of 1,481.43, the higher of Trend Line and Fair Value, would improve the structural case.
Breadth holding above 55% for several completed weeks would show that repair is spreading.
Positive 13 and 26-week relative performance would confirm that capital is rotating into the group.

This is a weekly research classification, not personal investment advice. Sentiment is reported as an independent confirmation layer and does not alter the technical score.
