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.
4 bullish / 0 bearish
Only ACGL
- EMA Ribbon Expansion Bullish — bullish, trend, medium horizon
- MACD Bullish Crossover — bullish, momentum, short horizon
2 bullish / 1 bearish, conflicted
Only QQQ
- MACD Bearish Crossover — bearish, momentum, short horizon
Both carry 2 more signals that do not separate them: Golden Cross Active, Uptrend Structure Active.
QQQ is conflicted, so the timing case there is weaker than the score alone suggests.

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.
