Price vs model alignment

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

HYGNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +0.2%, AIQ 0 points).

SPYConfirmed strength

Price and the AIQ Score both moved up over the latest session (price +0.53%, AIQ +4 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. 1HYG closes the Momentum gap — currently 29 points behind, the largest single contributor to SPY's edge.
  2. 2HYG's Death Cross Active resolves — a bearish trend rule currently active against it.
  3. 3SPY's conflicting signal state resolves bearish — it currently carries 4 bullish and 1 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.
