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.
3 bullish / 1 bearish, conflicted
- Golden Cross Active — bullish, trend, long horizon (24.03%)
- EMA Ribbon Expansion Bullish — bullish, trend, medium horizon
- Uptrend Structure Active — bullish, trend, long horizon

- Golden Cross Active — bullish, trend, long horizon (3.37%)
- Bollinger Band Squeeze — neutral, volatility, short horizon
- MACD Bullish Crossover — bullish, momentum, short horizon

- 3PTCT's Golden Cross Active breaks down — it is the strongest rule currently supporting the verdict.
- 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.
