- The AIQ gap is wide at 14 points. (supports the conclusion holding)
- Only 2 of 4 covered evidence groups agree. (argues the conclusion is provisional)
Stability combines the score gap, how broadly the evidence agrees, how steady the lead has been across daily snapshots, the current signal state on both names, and analyst dispersion on SPY.
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.
- 1BK closes the Quality gap — currently 37 points behind, the largest single contributor to SPY's edge.
- 2BK generates a confirmed bullish trend signal it does not currently carry, such as Golden Cross Active or MACD Bullish Crossover.
- 3SPY starts generating bearish momentum or trend signals.
- 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.
