Price vs model alignment
Whether the latest session's price move confirms what the model did over the same session, or contradicts it.

- 1PRMB closes the Quality gap — currently 34 points behind, the largest single contributor to LEGN's edge.
- 2PRMB's Bollinger Band Squeeze turns directional — it is neutral today and would confirm a change in trend.
- 3LEGN's conflicting signal state resolves bearish — it currently carries 1 bullish and 3 bearish rules at once.
- 4A regime shift changes factor weighting — Quality and Value carry the heaviest weights in the composite, so a rotation toward either would move the result most.

How this comparison is scored
The Algovestiq AIQ Score composites four factors — Quality, Value, Momentum and Risk, each carrying a fixed weight. Sentiment is reported separately as SentimentPulse and is not folded into the composite. Scores refresh every trading day, and this page regenerates from the latest snapshot rather than being written once.
The verdict names a leader, states how broadly six independent evidence groups agree, and rates how durable that conclusion is given the score gap, its recent trajectory and the current signal state on both names.
