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.

- EMA Ribbon Expansion Bullish — bullish, trend, medium horizon
- 52-Week High Proximity — bullish, risk, long horizon (0.7%)

- Golden Cross Active — bullish, trend, long horizon (5.86%)
- Bollinger Band Squeeze — neutral, volatility, short horizon

- 4The narrowing continues — the lead has already given back 3 points over 30 sessions, and a further 2-point move would eliminate SPY's advantage entirely.

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.
