Reading the VOO Bias Score

The Bias Score for VOO 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.
