Over the last 30 published readings, the BIIB Bias Score has ranged between +69 and +85, and the reading shown above sits around the middle of that range.
Every one of those readings was above zero, with no crossing in the window.
The score finished the window within 2 points of where it started, and the day-to-day movement has been steady.
The Bias Score for BIIB is produced by EquityBias's proprietary multi-layer scoring engine, which synthesises hundreds of public market data points each session into a single composite reading on a -100 to +100 scale. The engine re-calibrates as market regimes shift.
A score of +100 means our signal ensemble points strongly bullish in broad alignment. -100 means strongly bearish. Readings near 0 indicate either market neutrality or active disagreement between the engine's internal signal layers, measured separately as a divergence score. Which layers are on which side of that disagreement is part of the Premium breakdown.
