Investment implication
None of the engine's positive-conviction paths (C-quality, D-momentum) triggered — the F-path HOLD reflects balanced signals. Strongest-cleared gate: INSIDER:OK. Top dim: Sentiment at 7.4; weakest: Momentum at 3.6. No conviction either direction.
The strongest dimensions are Sentiment at 7.4, Risk (lower is worse) at 7.2, and Quality at 7.1; the weakest are Momentum at 3.6, Peer rank at 3.7, and Catalyst at 4.1. The V9 engine flagged 2 failed gates with 1 warning, producing an asymmetric reward-to-risk of 0.21 and an engine sizing output of AVOID.
