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.

KPTI leads the comparison while carrying a conflicted signal state, which is one reason the stability rating is not higher.

Price vs model alignment

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

IONSNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price -2.59%, AIQ 0 points).

KPTIDivergence

Price is down while the AIQ Score moved up 1 points over the same session — price and model disagree (price -0.62%, AIQ +1 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.

  1. 1IONS closes the Quality gap — currently 70 points behind, the largest single contributor to KPTI's edge.
  2. 2IONS's Death Cross Active resolves — a bearish trend rule currently active against it.
  3. 3KPTI's conflicting signal state resolves bearish — it currently carries 2 bullish and 3 bearish rules at once.
  4. 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.
