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 / 1 bearish / 1 neutral, conflicted
Only MTSI
- Golden Cross Active — bullish, trend, long horizon (1.05%)
0 bullish / 3 bearish / 1 neutral
Only POWI
- Death Cross Active — bearish, trend, long horizon (12.60%)
- Downtrend Structure Active — bearish, trend, long horizon
Both carry 2 more signals that do not separate them: ATR Expansion - Breakout Mode, MACD Bearish Crossover.
MTSI is conflicted, so the timing case there is weaker than the score alone suggests.
Price vs model alignment

Price is up while the AIQ Score moved down 1 points over the same session — price and model disagree (price +3.85%, AIQ -1 points).
Price and the AIQ Score both moved up over the latest session (price +2.73%, AIQ +1 points).
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.
- 1MTSI closes the Value gap — currently 18 points behind, the largest single contributor to POWI's edge.
- 2MTSI's MACD Bearish Crossover resolves — a bearish momentum rule currently active against it.
- 3POWI starts generating bearish momentum or trend signals.
- 4A regime shift changes factor weighting — Quality and Value carry the heaviest weights in the composite, so a rotation toward either would move the result most.

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.
