Price vs model alignment

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

SPYNo material change

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. 1WDAY closes the Risk Resilience gap — currently 48 points behind, the largest single contributor to SPY's edge.
  2. 2WDAY generates a confirmed bullish trend signal it does not currently carry, such as MACD Bullish Crossover.
  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 — the composite weights Quality and Value at 30% each, so a rotation toward either would move the result most.

How this comparison is scored

The Algovestiq AIQ Score composites four factors — Quality (30%), Value (30%), Momentum (25%) and Risk (15%). 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.
