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.
1 bullish / 2 bearish / 1 neutral, conflicted
- Death Cross Active — bearish, trend, long horizon (11.42%)
- Downtrend Structure Active — bearish, trend, long horizon
- ATR Expansion - Breakout Mode — neutral, volatility, short horizon (5.33%)
4 bullish / 0 bearish
- Golden Cross Active — bullish, trend, long horizon (13.41%)
- EMA Ribbon Expansion Bullish — bullish, trend, medium horizon
- Uptrend Structure Active — bullish, trend, long horizon
RMBS is conflicted, so the timing case there is weaker than the score alone suggests.

How this comparison is scored
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.
