Reference definitions for the terms used across the EquityBias platform. Each term has a short summary followed by an extended definition with context.
A single number from −100 to +100 summarising current market data per US equity.
A composite reading from −100 to +100 produced by EquityBias's proprietary multi-layer scoring engine. Synthesises hundreds of public market data points per stock per session into one comparable number. +100 = signal ensemble points strongly bullish in broad alignment. −100 = strongly bearish. Near 0 = either market neutrality or active disagreement between signal layers (see "divergence" for the latter).
A 0–100 indicator of how much the scoring engine's internal signals disagree.
Separate from the Bias Score, divergence quantifies how aligned the scoring engine's internal signal layers are with each other. Low divergence (e.g. 12) means signals point the same direction — the headline Bias Score is well-supported. High divergence (e.g. 68) means signals contradict each other — treat the headline with extra caution. Available to Premium subscribers.
A measure of how rich the underlying data was when computing the score.
Some stocks have rich, well-distributed data sources to draw from (heavy coverage, deep markets, frequent news). Others — smaller caps, recent IPOs — have sparser data. Confidence reflects how much information went into a given score. A low-confidence reading means there was simply less to work with, not that the score is wrong. Available to Premium subscribers.
The internal components of the scoring engine that combine into the Bias Score.
The Bias Score is produced by an ensemble model with multiple internal signal layers. Each layer processes a different dimension of public market data. We do not publish the layer composition, signal sources, or weighting — these are proprietary to EquityBias. Premium subscribers see a qualitative breakdown of how the layers are aligned for each stock.
Synonym for Bias Score — the unified −100 to +100 reading.
Used interchangeably with "Bias Score" across the platform. Emphasises that the score is composed by combining multiple internal signals rather than relying on a single indicator.
A significant overnight change in Bias Score for a stock.
A reason flag attached to picks where the Bias Score moved meaningfully between yesterday's close and today's open — typically driven by overnight news, analyst revisions, or post-close earnings. Identifies stocks where the data picture has changed quickly.
When the scoring engine's signal layers all point the same direction.
A reason flag for stocks where every internal signal layer points in the same direction (all bullish or all bearish). Coincides with low divergence — the headline Bias Score is well-supported by every underlying signal layer.
A stock moving against its sector's broader trend.
A reason flag for stocks where the Bias Score diverges meaningfully from the sector aggregate — a strong-bullish stock in a falling sector, or vice versa. Highlights potential idiosyncratic stories worth investigating.
A score with both high absolute value and high confidence.
A reason flag combining a strong-direction Bias Score (high absolute value) with high confidence (rich underlying data). The data picture is both clear and well-supported. Note: this does NOT mean "high probability of moving up/down" — it means the current data is unambiguous.
End-of-day. The Bias Score updates after US market close.
End-of-day. EquityBias is an EOD product — data is collected after US market close (~22:00 CET), scores are recalculated overnight, and new readings publish before the next US open. We do not provide intraday updates.
The scoring engine is periodically re-tuned as market regimes shift.
The scoring engine is not static. We re-calibrate the engine on a rolling basis as market regimes change — what was predictive in one regime is not necessarily predictive in another. Re-calibrations are applied methodically and never retroactively to historical scores. Specific timing, methodology, and parameter changes are not disclosed.
