What supports the view
- Medium-term relative returns and peer standing remain constructive.
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 current 13-week parent-relative trend is weakening.
- Stage 4 declining constituents exceed Stage 2 advancing constituents by 20 percentage points.
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.
