AIQ Signal Divergence
Only the signals that bear on the head-to-head. A conflicted name is carrying bullish and bearish rules at the same time — the technical evidence is not pointing one way.

- Bollinger Band Squeeze — neutral, volatility, short horizon
- EMA Ribbon Expansion Bullish — bullish, trend, medium horizon

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

Price is up while the AIQ Score moved down 3 points over the same session — price and model disagree (price +0.85%, AIQ -3 points).
What would flip this result
A state, not a forecast. These are the specific, observable changes that would reverse the verdict — not a price prediction.
- 1SPY closes the Value gap — currently 22 points behind, the largest single contributor to IAG's edge.
- 2SPY generates a confirmed bullish trend signal it does not currently carry, such as MACD Bullish Crossover or Uptrend Structure Active.
- 3IAG's conflicting signal state resolves bearish — it currently carries 1 bullish and 2 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.
